Executive Summary 

In the fall of 2008 and in the spring of 2009, Cambria Gordon (CGL), Metlakatla Fisheries and 

Esther Guimond began collecting baseline data in the tailpond at the BC Hydro’s Falls River facility, 

in order to monitor outcomes of recommended operational changes as part of BC Hydro’s Water 

Licence requirements. This report summarizes the baseline data gathered for Year 1 of a proposed 

3-year study, and is a component of a larger 5-year Water Use Plan (WUP) monitoring program. 

Field work for Year 2 of the study is planned for September of 2009. 

Main Objectives 

The following report outlines our initial efforts to assist BC Hydro to answer the key management 

question identified in the Falls River WUP: 

Do the minimum flows (6.5 cms from August 1 st to October 15 th during the salmon spawning period 

and 2.6 cms 1 for all other periods – i.e., incubation period for Chinook and coho) under the WUP 

operations produce adequate habitat conditions for egg-to-fry survival? 

The primary objective of the monitoring program is to reduce uncertainty related to the benefits of 

the minimum flows to the incubation of Chinook salmon eggs in Falls River. The ultimate objective of 

this study over the long term is to assess the outcomes of recommended operation changes (changes 

in flow regimes) to provide information on which to base future operation decisions, as outlined in 

the Falls River Project WUP Monitoring Program Terms of Reference (ToR) (BC Hydro 2006a). This 

study represents one of several monitoring programs recommended by the Consultative Committee 

(BC Hydro 2003), which are conducted according the Falls River Order under the Water Act (April 

2006). 

Critical Methods 

Egg incubation habitat information and physicochemical parameters (relating to both physical and 

chemical) were gathered on three survey dates between September 23 rd , 2008 and May 15 th , 2009. 

Survey dates were parallel with Chinook egg/fry development: eyed stage (September/October), 

hatch stage (November/December) and emergence stage (April/May). Timing of Chinook egg/fry 

development stages was predicted with estimated spawning timing and water temperature data 

(calculated Accumulated Thermal Units – ATUs). Sample sites (n=9) were chosen within two 

incubation areas and one control area. Physicochemical data, including dissolved oxygen (DO - 

mg/L), water temperature ( 0 C), conductivity (mS/cm), pH and salinity (ppt) were gathered at each 

sample site over the survey period. In addition to physicochemical parameters, modified Wolman 

pebble counts were conducted at each sample site to determine substrate composition and to 

monitor any temporal changes. In order to monitor water levels in the tailpond and develop a 

stage/discharge relationship through the Falls River facility (turbine and spillway discharge), a 

pressure transducer and water temperature probe, connected to a datalogger were installed along 

the right bank adjacent to the incubation areas. Two Tid-bit TM (redundancy in case one failed) 

temperature loggers were also installed as back-up to the Unidata temperature probe. 

1 If the reservoir elevation drops below 88.4 m, turbine discharge will be reduced to 1.3 cms to conserve water and ensure 

that some flows to the river can be maintained (BC Hydro 2006a)

Key Results 

The intragravel physicochemical parameters monitored during the sampling periods were all within a 

suitable range to support incubating salmon eggs. Dissolved oxygen ranged from a low of 9.6 mg/L 

to a high of 12.3 mg/L over 8 sample sites (control area had DO of 8.3 mg/L) (the BC guideline for 

intragravel oxygen include an instantaneous minimum of 6 mg/L and a 30-day mean not lower than 

8 mg/L; RIC 1998). The intragravel pH levels ranged from 7.4 to 7.9 (aquatic life generally 

supported in the range 6.5-9.0; RIC 1998). Water temperatures ranged from an average daily low 

of 0.2 0 C to an average daily high of 10.7 0 C over the baseline sampling period. Intragravel water 

temperatures and water column water temperatures were very similar for all sample sites. Salinity 

levels were not significant (0.05) between sites. A 

wide range of particle sizes were observed for incubation areas 1 and 2 (4 mm – 64 mm), with area 

2 showing a slightly larger cumulative distribution for large particle sizes. Overall, the incubation 

areas selected have adequate substrate for Chinook spawning. 

Contextualization 

Seasonal minimum flows recommended by the Consultative Committee (CC) for the Falls River WUP 

are based, in part, on estimated spawning timing for adult salmon and steelhead in the Falls River. 

The influence of these WUP flows on spawning and egg incubation; however, are highly uncertain as 

they were estimated from models with uncertain parameter estimates (Appendix G of BC Hydro 

2003). The current (2008/2009) study, and future monitoring for Falls River Fish Spawning Habitat 

in the Falls River tailpond, is directed at reducing this uncertainty, in order to guide future operating 

decisions.

1 INTRODUCTION 

Seasonal minimum flows recommended by the Consultative Committee (CC) for the Falls River 

Water Use Plan (WUP) are based, in part, on estimated spawning timing for adult salmon and 

steelhead in the Falls River. The influence of these WUP flows on spawning and egg incubation; 

however, are highly uncertain as they were estimated from models with uncertain parameter 

estimates (Appendix G of BC Hydro 2003). The current (2008/2009) study, and future monitoring 

for Falls River Fish Spawning Habitat in the Falls River tailpond, is directed at reducing this 

uncertainty, in order to guide future operating decisions. 

Cambria Gordon Ltd. (CGL) and Metlakatla Fisheries were retained by BC Hydro to conduct fish 

spawning habitat monitoring at BC Hydro’s Falls River hydroelectric project, in order to fulfill a 

component of BC Hydro’s Water License requirements for 2008. This report summarizes Year 1 of 

a proposed 3 year study, and is a component of a larger 5 year Water Use Plan (WUP) monitoring 

program. Field work for Year 2 of the study is planned for September of 2009. 

The following report outlines our initial efforts to assist BC Hydro to answer the key management 

question identified in the Falls River WUP: 

Do the minimum flows for salmon spawning and egg incubation provided under the WUP 

operations produce adequate habitat conditions for egg-to-fry survival? Relating flow 

(from this point on referred to as discharge) to water depth and velocity; for the 

recommended minimum flows, is a minimum water depth of 0.05 m and minimum 

velocity of 0.02 m/s maintained over Chinook redds during the incubation period? 

The ultimate objective of this study over the long-term is to assess the outcomes of recommended 

operation changes (changes in discharge regimes) to provide information on which to base future 

operation decisions, as outlined in the Falls River Project WUP Monitoring Program Terms of 

Reference (ToR) (BC Hydro 2006a). 

1.1 Study Area 

BC Hydro’s Falls River facility is located approximately 50 km southeast of Prince Rupert on the Falls 

River, which is a right bank tributary to the Ecstall River (Figure 1). The project has a single 

reservoir, located above a large, natural rock waterfall. Two penstocks carry water to turbines 

located in the powerhouse at the base of the falls. Water is discharged from the turbines into the 

tailpond, which extends from the base of the falls to the top of a tidal rapid approximately 175 m 

downstream. The tailpond is approximately 100 m wide by 200 m long (1.5 ha) and is the focus 

area for the study (Figures 2 and 3). Baseline incubation sample locations were selected along the 

right bank (river right – north side) of the tailpond. Site access is by boat, float plane or helicopter 

only. Float plane access is restricted at tide heights below 1.5 m during low flow periods on the 

Ecstall and Falls Rivers.

1.2 Periodicity Review and Incubation Assessment 

1.2.1 Periodicity Review 

A periodicity review was conducted in 2007; a component of a report written for BC Hydro as part 

of a 5 year Water Use Plan (WUP) monitoring program (CGL and Metlakatla Fisheries, 2007), 

focusing on historic and anecdotal fish presence, migration and spawning timing information for 

steelhead, Chinook, chum, coho and pink salmon for the Ecstall and Falls rivers. 

Results of the review that focused on Chinook salmon are summarized below. 

Migration into the Ecstall River occurs in late July and August. Spawning occurs in early September 

(FISS). Migration into the Falls River system occurs in late August; spawning begins late in August 

and peaks in early September and may continue through October (FISS). Chinook spawners and 

redds have been noted in the Falls River tailpond in late August and early September by a variety of 

sources (Redenbach 1981; Hickey 1981; Bullock, R. pers. comm.; William Beynon, pers. comm.). 

Chinook presence and spawning has been recorded in the Falls River tailpond at the base of the falls, 

below the powerhouse and in gravel areas downstream between 1955 and 2003. Observations 

typically occur between August 12 th and September 22 nd ; however dates are not provided for some 

years (DFO, BC 16’s Summary Sheet). 

BC Hydro staff indicated that a detailed fisheries assessment, focused on potential habitat 

rehabilitation at the Falls River facility, was completed in 1980 (B. Mossop, pers. comm. - 2007 re: 

Redenbach 1981). During the Redenbach (1981) study, bright Chinook were angled and observed 

in the Falls River between August 20 th and 30 th , 1980. In the following year, from August 7 th to 

September 23, 1981, a total of 15 possible salmon redds were noted in the tailpond, including 2 

confirmed Chinook spawning pairs (Hickey 1981). 

Between April and October, 2007 and during the same period in 2008, a total of 14 snorkel and 

angling surveys were conducted for BC Hydro as part of a 5 year Water Use Plan (WUP) monitoring 

program (CGL and Metlakatla Fisheries 2007; CGL and Metlakatla Fisheries 2008). No adult 

steelhead or salmon were viewed in the tailpond during these surveys. 

For the purposes of this study, we used an estimated spawning timing for Chinook salmon from mid 

August until late September to help plan timing of field work. 

1.2.2 Incubation Assessment 

In 2003/2004 Fisheries and Oceans Canada (DFO) and Northcoast Environment conducted a 

Chinook incubation study in the Falls River tailpond, in follow-up to a feasibility study conducted in 

2002 (Miller et al., 2002). During this study, one pair of Chinook spawners and 7 redds (assumed 

to be from Chinook and pink salmon) were observed in the Falls River tailpond in early September, 

2003 (Figure 4). The study team noted that redds located in the tailpond were flattened by spilling 

outflows, and were no longer visible the next day. For the incubation component of the study, 22 

Jordan Scotty cassettes with 200 Chinook (fertilized on site) eggs per cassette were buried at 4 sites 

(Figure 4) on September 9th, 2003. Table 1 displays the percent survival rate to eyed, and hatch 

stages found on survey dates conducted on January 13th and March 3 rd of 2004.

To reduce uncertainty in terms of egg to fry survival, a portion of the eggs from the Chinook doe 

(1900) and milt from two Chinook males, used for the egg-take at Falls River, were flown to Deep 

Creek Hatchery near Terrace, fertilized and placed in heath trays to act as a control. Egg to fry 

survival at the hatchery for the control group, was noted to be good (Miller and Northcoast 

Environmental, 2004, unpublished data). Table 2 shows the water column physicochemical 

parameters gathered during the study. Note: intragravel physicochemical data was not gathered 

during this study. Table 3 shows the average water velocity and average water depth data gathered 

at select sites (see Figure 4 for sites and locations).

Overall Site 1 had the highest survival rate to March 3, 2004, which may be a result of potentially 

higher dissolved oxygen in relation to the site’s proximity to outflow from the turbines, and the 

higher potential for sediment flushing at this site. This is purely speculation as the baseline data 

collected is limited to a few points.

2 METHODS 

2.1 Survey Design 

The primary measures of interest for the 3-year Habitat Monitoring Survey will be to investigate: 

1) Relative egg-to-fry survival across sample sites over time; 

2) The relationship between egg-to-fry survival at sample sites and water flow/discharge; and 

3) The relationship between physicochemical parameters at sample sites and water 

flow/discharge. 

Year 1 will assess only the physicochemical parameters and years 2/3 will assess both 

physicochemical parameters and Chinook egg-to-fry survival. 

In the present study (Year 1), priorities for survey design include: 

1) The selection of study sites; and 

2) The measurement of characteristics of incubation habitat (substrate composition and 

physicochemical parameters). 

Incubation areas that were selected represent a range of physical habitat typical to Chinook spawning 

habitat in Falls River. Baseline spawning habitat information (water depth/temperature, 

physicochemical parameters, substrate size and composition, discharge) was collected in the tailpond 

at the Falls River facility to assess the overall quality of salmon egg/fry incubation habitat and 

measure factors that are known to affect egg/fry incubation. 

Data collection in the study area was timed to coincide with low tide in order to access the sites 

without the use of SCUBA gear. 

2.1.1 Incubation area/Site Selection 

The selected incubation area locations were based on two site visits conducted prior to the initial 

baseline site visit. At the first site meeting, in June of 2008, which included Karla Robison and Brent 

Mossep from BC Hydro, Lana Miller from the Department of Fisheries and Oceans, and Esther 

Guimond, a consultant on the project, overall site logistics in terms of accessing areas efficiently and 

safely were discussed as well as reviewing Lana Miller’s 2003 incubation study. From this meeting it 

was decided that three incubation areas would be selected on the right bank, eliminating the need to 

ferry equipment across to the left bank, and thus maximizing time spent during the available low tide 

window. A second site visit conducted in September of 2008, during which site conditions allowed 

for survey work on substrate depth along the right, bank, narrowed the selection to two incubation 

areas, both in close proximity to a incubation area used in the 2003/2004 incubation study (Site 

#2, see Figure 4). Overall incubation area selection was based on: 



� Gravel depth and quality; and 

� Access to the shore, which would allow for efficient and safe monitoring during the low tide 

window (approximately 2 hours). 

Gravel depths were measured during a September 23 rd site visit, where piezometer installation was 

tested at several locations on the right bank near the bedrock outcrop. The installation of the 

piezometers indirectly resulted in a survey of gravel depth as; during installation, bedrock was 

reached at several locations when attempting to install the piezometers. In addition to substrate 

depth, a coarse visual estimate of the size range of gravels encountered was conducted in 

accordance to the substrate requirements for Chinook spawning (i.e. gravel sizes in the range 25 – 

305 mm - Hanrahan et al., 2004). 

2.1.2 Survey Timing 

Based on a periodicity review conducted in 2007 (CGL and Metlakatla Fisheries 2007), expected 

peak Chinook salmon spawning occurs in late August and early September. Data were collected 

during three survey periods between September 23 rd , 2008 and May 15 th , 2009). Survey dates were 

parallel with important stages of Chinook egg/fry development: eyed stage (September/October), 

hatch stage (November/December) and emergence stage (April/May). Timing of Chinook egg/fry 

development stages (eyed, hatch, and fry emergence) was predicted (Figure 9) with estimated 

spawning timing of Chinook salmon and water temperature data (calculated Accumulated Thermal 

Units – ATUs) collected from temperature loggers (described in section 2.2.5). 

To predict the timing of Chinook egg hatch and fry emergence for year 2 of the current study, water 

temperature data (available from September 23, 2008 to May 15, 2009), were converted into 

accumulated thermal units (ATUs), where one degree Celsius in one day is equal to one ATU. The 

15 minute interval temperature dataset was averaged over one day, and ATUs were calculated. 

2.2 Intragravel/Physicochemical Parameters 

Based on the initial survey design, Piezometers were installed at depths of 25 cm – 40 cm in the 

stream substratum (which is analogous to depths of incubation cassettes (Chinook redd) to be 

installed in year 2). The procedure for piezometer installation was based on that described by Baxter 

et al. (2003) and is further described in Appendix IV. After initial installation of the piezometers on 

September 23 rd , 2008 and on October 27 th , 2008, obtaining samples from the piezometers was not 

possible due to a slow re-charge rate. Furthermore, during the February 19 th , 2009 survey date, it 

was discovered that two of the installed piezometers in incubation area 2 (H) and at the control area 

had been dislodged from the substrate (due to high flow conditions and/or ice movement). Three of 

the four remaining piezometers at incubation area 2 had been bent from high flow conditions, and 

were no longer functional in terms of intragravel sampling (see Figure 5). 



Figure 5: Photos displaying piezometers bent by high flow (Incubation area 2) 

In the current study, a metal sampling syringe was used to extract intragravel water samples from the 

hyporheic zone to measure dissolved oxygen (DO), conductivity, temperature (C) and pH (see Figure 

6). The metal sampling syringe was used in place of sampling from the piezometers and was utilized 

throughout the sampling period at all the sample site locations to maintain consistency amongst 

sampling locations. Piezometers were left in place at sample sites and will be utilized as indicators of 

sample sites (i.e., place-markers). 

The metal sampling syringe has three major components: (1) a perforated probe end, (2) a water 

collection chamber, and (3) a plunger (Figure 6). The probe end of the syringe was pushed as deep 

as possible (20 – 28 cm) into the substrate to extract hyporheic water (Figure 7b and 7c). Water was 

extracted by pulling on the plunger and was then placed into a 250 ml graduated cylinder to obtain 

physicochemical measurements. The syringe was also used to sample water column samples at the 

time of installation to look at any equipment bias between non-syringe water column samples. This 

syringe method did not allow for estimates of vertical hydraulic gradient (VHG) and hydraulic 

conductivity (K). 

In order to maintain consistency and allow for comparison between study years, the metal sampling 

syringe will be used in years 2 and 3. 

Figure 6: Metal sampling syringe used to extract intragravel samples. 



The following physicochemical parameters were measured during each visit: 

2.2.1 Dissolved Oxygen 

Water column and intragravel dissolved oxygen was measured (in mg/L) at each sample site using a 

YSI Pro Plus multi-meter. Note triplicate measurements were not always possible at all sites, due to 

tidal backflow, which limited the amount of sampling time in the tailpond. 

2.2.2 Conductivity 

Conductivity (ms/cm) was measured on intragravel and water column samples collected at each 

sample site using a YSI Pro Plus multi-meter. 

2.2.3 pH 

Water pH was measured on intragravel and water column samples collected at each sample site 

using an Oakton waterproof pHTestr. 

2.2.4 Salinity 

Salinity was tested in the water column at the time of installation of the piezometers using a YSI Pro 

Plus multi-meter. Salinity was not collected at all sample dates, as an initial reading (ppt) of 0.0 

(rising tide). Further salinity sampling will be conducted in year 2 to confirm the absence of a salt 

wedge, as noted by Miller and Northcoast Environment (2003) and Hickey (1981). 

2.2.5 Water Temperature 

To determine water temperatures in the Falls River tailpond, a Unidata 15k ohm water temperature 

probe was installed. The temperature probe senses every 1 minute, logs every 15 minutes and is 

time stamped in PST (GMT-8). The memory capacity at this interval is estimated at 424 days (see 

Figure 7 for site photos of the installation and Appendix III for a detailed description of the probe 

installation). In addition, two Tid-bit TM temperature loggers (redundancy in case one failed) were 

installed to measure intragravel temperature and served as back-up to the Unidata temperature 

probe. The water temperature probe is housed in a 5’ aluminum pipe. This pipe is rock bolted to a 

large rock on the right bank. The cables are protected in flexible aluminum conduit and terminate 

inside an aluminum shelter which houses the data storage unit (Figures 7 and 10). 

Data from the temperature probe were downloaded from the data storage unit onto a laptop 

(Starlogger V.3 software) during two subsequent visits following initial installation. Temperature data 

was used to calculate the accumulated thermal units (ATU - daily mean temperature multiplied by 

the number of days of incubation) which are used to predict hatch and emergence timing of Chinook 

eggs. 

2.3 Water Depth and Discharge 

Adequate water levels are essential throughout salmon egg/fry incubation to ensure redds are wetted 

(to avoid desiccation) and to prevent freezing of eggs. To determine water depth at incubation areas 

1 and 2 in the Falls River tailpond, a Keller 2.5 v 5.0 m pressure transducer (a continuous recording 



device) was installed on September 23 rd , 2008 on river right (Figures 7 and 10). Due to concerns of 

high flow conditions and the possibility of snagging of the conduit tubing from debris and/or ice, 

installation of the pressure transducer at either of the 2 incubation areas selected was not practical. 

The water temperature probe is housed in a 5’ aluminum pipe. This pipe is rock bolted to a large 

rock on the right bank. The cables are protected in flexible aluminum conduit and terminate inside 

an aluminum shelter which houses the data storage unit (Figure 7). 

Three benchmark elevations were established to instill confidence in the accuracy of water depth 

readings. Permanent rock bolts were installed in the vicinity of the pressure transducer and known 

elevations (from tailpond substrate level) were determined with a survey rod and level (1.451 m, 

1.798 m, 1.117m). Benchmarks were adjusted to the pressure transducer zero at 0.000 m on 

September 23, 2008. At the time of installation, the depth was 0.826 m. Accuracy of water depth 

readings from the pressure transducer were confirmed by cross-referencing with actual water depth 

readings taken with a rod and level at the three known benchmark elevations and water surface 

elevation. 

Water depths were recorded every 15 minutes at the pressure transducer location. The transducer 

was installed at a substrate depth that is lower than the stream substrates at incubation areas 1 and 

2. Actual water depth was measured at each sample site using the graduations on the wading rod. 

(see Figure 8a). Average hourly water depths at each incubation area can be estimated with the 

following equations: 

Incubation area 1: Avg water depth = Actual water depth (transducer) – 19 cm 

Incubation area 2: Avg water depth = Actual water depth (transducer) – 42 cm 

Water depth in the Falls River tailpond is also influenced by a semidiurnal tidal cycle. Hourly tidal 

heights at Prince Rupert were obtained from Fisheries and Oceans Canada (http://www.lau.chsshc.gc.ca/english/Canada.shtml) 

to examine the tidal influence on water depth measurements in the 

study area and are included in Appendix II. 

2.3.1 Water Velocity and Discharge levels 

Water velocity was measured at each sample site (n=9) using a propeller-type flow-meter (Swoffer 

Model 3000) mounted to a 2.0 m wading rod. Readings were taken at 0.6 of the depth with the 

Swoffer meter set to display a 40-second average. 

BC Hydro provided average hourly discharge levels (cms) which included the power generating 

outflow through the turbines and the non-power generating flow over the spillway.

2.3.2 Data Analysis 

To analyze the effect of total discharge rate on water levels, tidal influence was detached from the 

water depth data in the study area. Hourly tide chart readings (Appendix II) were cross referenced 

with actual water levels (hourly data obtained from the pressure transducer) and tidal peaks 

(considered ‘noise’) were manually identified. Data points which were exaggerated by tidal influence 

were excluded from the data-set to reduce noise and augment the underlying data analysis. 

Pearson’s product-moment correlation analyses were then applied to the discharge/water level data 

to determine if a linear relation exists between total discharge levels and water depth in the tailpond. 

2.4 Substrate Composition (Wolman Pebble Counts) 

The particle size characteristics and potential temporal changes of particle size at each sample site 

were assessed using modified Wolman pebble counts (Wolman 1954). The Wolman pebble count 

involves a surveyor following a transect across a river stream width with heel/toe steps, picking up 

the first particle touched by a pointed index finger at the tip of the boot. This is performed until 100 

particles are measured. Since our study areas and sample sites were relatively small, we used a grab 

technique where the observer sampled as much substrate at each sample site (n=9), that could be 

held in both hands. The sample was then taken to the shoreline, where the intermediate diameter of 

each selected particle was measured with a gravelometer (a piece of aluminum metal with 14 square 

holes of common sieve sizes (1/2-phi unit classes) ranging from 2 mm to 180 mm). This was 

performed until 100 particles were measured. The Wolman pebble counts were conducted 3 times 

during the study: at the eyed stage (September 23 rd –October 27 th , 2008), February 19 th , 2009, 

and at the emergence stage (early May 12 th , 15 th , 2009).The crew member completing this task 

differed between the three sampling periods; however, on a survey date the same observer was used 

at all 9 sites to sample the substrate. See Figure 8 (e and f) for photos of substrate sampling, as well 

as an overhead view of the surface substrate at incubation area 2 (photo d). 

Data from the Wolman pebble count were arranged and analyzed according to size (13 size classes, 

ranging from 2.8 to 180 mm). The percent frequency and cumulative percent finer for each size 

class were then calculated and plotted (cumulative frequency curve and particle size histogram).

In order to predict Chinook hatch and emergence timing during year 2 of the study, water 

temperature data (available from September 23, 2008 to May 15, 2009), were converted into 

accumulated thermal units (ATUs), where one degree Celsius in one day is equal to one ATU. The 

15 minute interval temperature dataset was averaged over one day, and ATUs were calculated. 

Based on a periodicity review conducted in 2007 (CGL and Metlakatla Fisheries 2007), where peak 

Chinook salmon spawning was estimated to occur in late August and early September. Figure 9 

shows the calculated ATUs and dates expected for hatch and emergence stages for incubating 

Chinook eggs (will be installed at the eyed stage of development – see section 4.0) over a three 

week period initiating on September 23 rd . A three week window was used in order to buffer for a 

range of spawning timing as well as expected changes in water temperature for 2009/2010 in 

relation to 2008/2009 temperatures. All estimated eyed, hatch and emergence stage timing is based 

on ATU data for Chinook salmon from DFO (DFO 2003).

spawning as determined in a periodicity review conducted in 2007 (CGL and Metlakatla Fisheries 2007).

3.2 Intragravel Physicochemical Parameters 

Groundwater/stream-water exchanges in gravel and cobble beds have been found to relate to the 

selection of fish spawning habitat (Geist and Dauble 1998; Baxter and McPhail 1999; Baxter and 

Hauer 2000; Geist 2000; Geist et al. 2002; Baxter et al. 2002; and Douglas, 2006). The zone of 

interaction between to the two water sources forms a volume of saturated sediment called the 

hyporheic zone (Edwards 1998), which varies between systems dependent upon the extent of 

groundwater and surface water in the system. 

In this study, water from the hyporheic zone was sampled from 9 sample sites (marked with installed 

piezometers) located within two potential incubation areas and one control area. Figure 10 displays 

the incubation areas and location of the sample sites/piezometer markers. A metal sampling syringe 

was used in place of sampling from the piezometers (as discussed in methods) and was utilized 

throughout the sampling period at all sample sites. 

Water depth, average velocity, tidal information, and sample time (gathered during the sampling 

period September 23 rd , 2008 to May 15 th , 2009) are presented in table 5. Physicochemical 

parameters (dissolved oxygen, temperature, pH, conductivity) measured at all sample site locations 

are presented in Table 6. Due to the proximity of site H to site G, physicochemical data sampled 

from G were used for H.

Salinity 

(ppt)


Two physicochemical parameters critical for salmon egg to fry survival are dissolved oxygen (mg/L) 

and water temperature ( 0 C). In addition, water velocity (m/s), and water depth (m) are also critical for 

egg to fry survival (Bradford and Taylor 1995; Baxter and McPhail 1999; Geist et al. 2002; Soulsby 

et al. 2002; Hanrahan et al. 2005). 

The intragravel physicochemical parameters monitored during the sampling periods were all within a 

suitable range to support incubating salmon eggs. Dissolved oxygen ranged from a low of 9.6 mg/L 

to a high of 12.3 mg/L over 8 sample site locations (control site had DO of 8.3 mg/L) (the BC 

guideline for intragravel oxygen include an instantaneous minimum of 6 mg/L and a 30-day mean 

not lower than 8 mg/L; RIC 1998). The intragravel pH levels ranged from 7.4 to 7.9 (aquatic life 

generally supported in the range 6.5-9.0; RIC 1998). Water temperatures ranged from an average 

daily low of 0.2 0 C to an average daily high of 10.7 0 C over the baseline sampling period, which is a 

suitable water temperature range for Chinook egg to fry development (RIC 1998). All water 

velocities exceeded the recommended minimum of 0.02 m/s. Intragravel water temperatures and 

water column water temperatures were very similar for all sites. 

3.3 Water Depth and Discharge 

Discharge data from the project site was obtained from BC Hydro and includes discharge through 

the generation facility and spills over the weir. Discharges over the study period ranged from a low 

of 2.24 cms for a short period on January 10 th to an hourly high of 264.56 cms (October 22 nd , 

2008 – storm event). Figure 11 shows the average daily discharge over the study period. Note: 

discharge data is not available from Dec 28th, 2008 – Jan 6th, 2009. 

Water depth data were collected from the pressure transducer gauge. Data points which were 

exaggerated by tidal influence were excluded from the data-set to reduce noise and augment the 

underlying data analysis. (as previously described in Methods 2.3.2).

2008 to May 21, 2009. Red line displays the WUP recommended minimums discharge during the salmon 

spawning period (6.5 cms – August 1 st to October 15 th ) and year round minimum discharge (2.6 cms). If the 

reservoir elevation drops below 88.4 m, turbine discharge will be reduced to 1.3 cms to conserve water and 

ensure that some flows to the river can be maintained (BC Hydro 2006a). Data is not available from Dec 28 th , 

2008 – Jan 6 th , 2009. 

3.3.1 Stage/Discharge Relationship 

We used the dataset of hourly depth and associated hourly discharge to attempt to develop a stage 

discharge curve at the site. This analysis provided strong correlations for some months, but weak 

correlations for others. 

The nine graphs in Figure 12 show the relationship between total discharge into the tailpond and 

water depth for the nine sample months. From September to December, 2008 there are strong 

positive correlations (R 2 0.936 to 0.977) between adjusted depth data (tidal back flow depths 

removed from the dataset) and total discharge. Weak correlations exist between total discharge and 

water depth from January to May, 2009 (R 2 = 0.074 to 0.5372). This could be a result of algae 

growth and/or debris build-up on the screen of the pipe that houses the transducer and/or ice buildup 

on the shoreline affecting representative water depths and/or affecting how discharge is 

distributed into the tailpond. Discharge data from the turbines and spillway will also be verified with 

BC Hydro to ensure that flow monitoring was accurate during this period.

3.3.2 Water Depth in the Study Area 

Water depth in the study area was recorded every 15 minutes at the datalogger location. The 

transducer of the logger was installed at an elevation lower than the stream substrates at incubation 

area 1 (transducer is 19cm lower) and incubation area 2 (42cm lower). Table 7 shows the 

relationship between water depths at the pressure transducer and incubation areas 1 and 2, as 

measured during the three field visits.

The highest depth recorded (except during tidal inundation) was 3.02 m (a storm event on October 

22nd, 2008), which corresponded to the highest hourly discharge of 264.56 cms. 

The lowest hourly water depth data during the study period was at incubation area 2 from Jan 4th to 

6th 2009. The data indicate that area 2 emerged from the water surface by 14 cm between periods 

of tidal inundation. During this period, area 1 remained covered by at least 9 cm of water. Average 

hourly discharges during this period are not available. 

Observers were not at site during this time, and the relationship between total discharge and water 

depth is not positively correlated from January to May of 2009, as ice build-up on the shoreline may 

be affecting representative water depths and/or affecting how discharge is distributed in the tailpond; 

therefore when considering the low depth reading in January, the relationship between the depth 

gauge and sample locations should take into consideration ice-build-up as a possible explanation. 

Follow-up data from year 2 gathered from the installation of pressure transducer/dataloggers at the 

incubation areas is proposed to reduce the uncertainty in this relationship. 

See Appendix 1 for average hourly: water depth and discharge (total) data. 



3.4 Substrate Composition (Wolman Pebble Counts) 

Substrate size has been used to link salmon redd site selection and incubation success in numerous 

studies (Lostpeich and Everest. 1981; Tappel and Bjornn 1983; Bradford and Taylor 1995; Geist 

and Dauble 1998; Kondolf 2000; McBain and Trush 2001; Merz et al. 2004: Hall and Wissmar 

2004; Hanrahan et al. 2005; and Zimmerman and Lapointe 2005). We sampled substrate at each 

sample site location in areas 1 and 2 at the initial (September 23 – eyed stage), post-hatch (February 

19th, 2009), and emergence (May12th-15th, 2009) stages of the incubation monitoring period. 

Sampling at each sample site location over different periods allowed for analysis of temporal changes 

in substrate composition and distribution of particle sizes at each site. 

Statistical analysis (Pearson’s chi-square test using contingency tables) of particle sizes at each 

sample site over time showed that there was no significant difference between sites (p value >0.05). 

Therefore, particle size distribution counts for each site were averaged for the three time periods. 

The distribution of particle sizes and changes in cumulative size distribution of particles at each 

study site (size classes (x-axis) are log 2 transformation of ½ phi steps) from the pebble counts are 

shown for each site and sample date in Figure 13. 

A wide range of particle sizes were observed for incubation areas 1 and 2 (4 mm – 64 mm), with 

area 2 showing a slightly larger cumulative distribution for large particle sizes. Overall, the 

incubation areas selected have adequate substrate for Chinook spawning.

4 RECOMMENDATIONS FOR YEAR 2 

Due to depth/discharge discrepancies encountered in 2009, additional winter site visits are 

recommended in January and February of 2010 to monitor ice conditions on site and how this may 

relate to discharge and depth. Winter surveys would also provide the opportunity to monitor the 

relationship between the pressure transducer depth and manual depth measurements from the 

sample site locations. In year 1, there were concerns of damage to and/or loss of water level 

recorders installed at the incubation locations as seen with some of the piezometers which were bent 

during the study period in year 1. The installation of relatively inexpensive non-vented pressure 

transducer/data-loggers at incubation areas 1 and 2 alleviating the equipment loss versus expense 

risk is proposed for year 2. In conjunction with the water level recorder currently installed on the 

right bank, the proposed pressure transducer/data-loggers installed at the incubation areas would 

allow for monitoring of both recording methods; reducing overall uncertainty with regards to water 

level. 

In order to maintain consistency and allow for comparison between study years, the metal sampling 

syringe will be used to extract intragravel samples in years 2 and 3. The piezometers currently 

installed at area 1 (which were not bent based on last survey May 12 th , 2009) could be used to 

calculate hydraulic head and permeability. 

The Falls River Project Water Use Plan Monitoring Terms of Reference (BC Hydro 2006a) for the 

Spawning Habitat Monitoring study recommends commencing the egg incubation phase (Year 2 and 

3) of the study using green eggs. Chinook salmon gametes (eggs and milt) would be obtained from a 

nearby hatchery facility (e.g. Kitimat Hatchery) and transported to Falls River, fertilized on site and 

buried at the selected incubation sites. However, the use of green eggs as a starting point for the 

incubation study increases the risk of confounding survival results from egg mortality due to embryo 

quality, egg collection and fertilization procedures. The remoteness of the Falls River site and 

proximity of hatchery facilities that could supply Chinook eggs, the logistics of arranging travel into 

the site, and the need to complete the work during a narrow window of conditions (discharge, tides, 

weather) create several challenges that could affect the study if green eggs are used. Viability of 

Chinook gametes may be negatively influenced with increasing storage times. Therefore, we are 

proposing to use eyed eggs for the study since there is a greater degree of flexibility in the availability 

of the eggs and they are much easier to transport at this stage. 

Incubators will be buried at two incubation areas, rather than three as described in the TOR. This 

decision was made following various site visits to the Falls River between August 2008 and April 

2009 during which time spawning habitat and site conditions in the river could be more carefully 

evaluated. The key issues considered were site access and crew safety, equipment installation and 

the ability to complete environmental monitoring tasks during low tides. The two incubation areas 

selected are located on the right side of the river and were utilized in a previous incubation study in 

2003 by DFO (L. Miller and Northcoast Environmental - unpublished data – see Section 1.2.2 and 

Site #2 in Figure 4). Area 1 is located in an area between the right bank and a bedrock outcropping 

while Area 2 is located just downstream of the outcrop (Figure 10). 

Eyed Chinook eggs will be transported from the selected Hatchery facility to the Falls River site on 

the day of installation. Once at the site, eggs will be loaded into Jordan-Scotty incubation cassettes 

with 100 eyed eggs filling cells in the bottom-half of each cassette. Although the cassettes are 



designed to hold 200 eggs, there is concern that the availability of Chinook eggs from local 

Hatchery facilities may be limited, based on discussions with Hatchery Managers. The statistical 

analyses of the study results will be more powerful if more incubators with fewer eggs (i.e. 8 

incubators with 100 eggs) as opposed to fewer incubators with more eggs (i.e. 4 incubators with 

200 eggs) are used, to deal with the variability in survival and differential survival rates between sites. 

Eight incubation cassettes will be buried at each incubation site for a total of 16 cassettes (1600 

eggs) for the study group. The cassettes will be buried in an artificial redd excavated in the substrate, 

in groups of two placed 30-40 cm apart, to a depth of ~25 cm, such that the top of each cassette 

will be approximately 10-15 cm below the surface of the gravel (Figure 14). Each cassette will be 

secured by a 50 cm length of ¼ inch polypropylene rope to a 30 cm length of rebar, driven into the 

substrate upstream of the cassettes. Cassettes will be flagged with an ID number so they can be 

easily located. 

A control group of eyed eggs from the same donating adults will remain separate at the Hatchery 

facility. The primary purpose of this group will be to demonstrate that there were no fertilization or 

survival issues with the batch of eggs used in the study when incubated in an ideal environment. The 

treatment of this group of “control” eggs in the same manner as the study group will require that 

eyed eggs be placed in Jordan-Scotty incubation cassettes and incubated to the fry/emergence stage 

in upwelling incubators (Atkins cells) or other upwelling bulk-type incubator at the designated 

facility. If this can not be accommodated due to restricted facility operations, space or availability of 

eggs, then the “control group” should be handled using standard hatchery practices of the facility 

such that the eyed eggs from which the study group was taken can be maintained separate from 

other groups at the hatchery, and survival tracked to the hatch and fry/emergence stages. 

Assessment of incubation success will be checked during two stages: at the hatching stage (~520 

ATUs), and at the fry/emergence stage (~920 ATUs). Based on water temperatures and ATUs from 

2008/2009 this would equate to survey times in early November (hatch) and early May 

(emergence). The incubators to be used in this study (Jordan-Scotty incubators) have blocked escape 

holes which permits more accurate assessment to the fry stage with no loss of embryos. The 

developmental stage of the incubating eggs will be monitored using temperature data collected from 

a buried Tidbit temperature logger at the Falls River site to calculate ATUs and schedule the egg 

assessment date at the hatch and fry stages. Hatch and emergence site visits will be adjusted from 

the 2008/2009 temperature dataset if required (i.e., if water temperatures are warmer or colder at 

the time of incubations cassette installation in September). 

For each developmental stage inspection, four cassettes from each site will be removed and 

assessed. The contents of the incubators will be emptied into a shallow basin and the number of 

dead and live eggs/alevins and fry enumerated. The embryos (live and dead) will be handled as per 

conditions in the Transplant Permit. Cassettes removed at the hatch stage will not be replaced in the 

gravel after assessment due to the amount of disturbance that would be required to excavate and 

replant the incubators. This disturbance could adversely affect the embryos in the cassette, as well as 

alter the intragravel conditions of flow, permeability and dissolved oxygen delivery within the ‘egg 

pocket’ or the surrounding environment of other nearby cassettes, thereby skewing results for the 

final stage of development.

Appendix IV 

Piezometer Installation Procedure 



The procedure for piezometer installation was based on that described by Baxter et al. (2003) (as 

shown in Figure 1) as follows: 

1. The driver mechanism (the casing with the driver rod inserted) was placed on the stream 

bottom and driven to the desired depth into the streambed by repeated blows with a 

sledgehammer; 

2. The steel driving rod was removed while the imbedded casing was held in place; 

3. the PVC piezometer was inserted into the casing; and 

4. While the piezometer was held in place the steel casing was removed, leaving only the 

piezometer inserted in the streambed. 

5. 

Figure 1: Diagram depicting piezometer installation method (from Baxter et al. 2003). 



The casing was 1.50 m in length and constructed from 33 mm steel pipe (inside diameter was 25 

mm) with a steel collar ring welded at the top. The pipe was painted white with Rustoleum and 

marked at 10 cm intervals from the bottom- up to assist in piezometer placement (Figure 2a). The 

driver rod was made of solid steel that fit snugly inside the casing and had a machined point on one 

end. A steel collar ring was welded approximately 15 cm from the top of the rod to prevent the 

driving rod from sliding all the way through the casing. 

The piezometers consisted of a 21 mm diameter polyvinyl chloride (PVC) pipe (inner diameter 15 

mm). Each pipe was 60 cm long and plugged with a 4 cm wooden dowel, which was inserted into 

the pipe and secured with a wood screw to prevent gravel from entering the piezometer (from the 

base) (Figure 2b). This dowel also allowed for the addition of a hollow wall anchor through the 

center of the dowel to prevent the piezometer from being removed due to high water, flows, ice, 

etc. The use of hollow wall anchors allowed for the anchor device to slide down the large steel 

casing and open to approximately 4 cm x 1 cm in the substrate. Anchors extended approximately 4 

cm below the piezometer. The lower 10 cm of the piezometer above the wooded dowel was 

perforated with 8- 9 mm holes (4 on either side) 

Figure 2: a) Driver mechanism consisted of a casing (white) and a driving rod. b) Piezometer constructed from 

21 mm diameter PVC pipe. c) Dynaline 17 oz. suction gun and tubing. 



Piezometers were installed to depths of 25 cm – 40 cm in the stream substratum, comparable 

depths for incubation cassette (Chinook redd) installation in year 2. Figure 3 (photos a-e) show 

piezometers being installed as well as three installed piezometers (photo f- Site 1). Water was 

extracted from the piezometers using a short length of plastic tubing attached to a Dynaline 17 oz. 

suction gun (Figure 2c). Water was extracted from the piezometer and placed in a 250 ml graduated 

cylinder to obtain physicochemical measurements. The suction gun enabled water to be extracted 

smoothly using a steady pressure to limit the introduction of atmospheric oxygen caused by water 

mixing and excess pumping. Table 1 displays the UTM location and depth of installation for each 

piezometer.
