The primary mission of the Candlewood<br />

Lake Authority <strong>Marine</strong> <strong>Patrol</strong> (<strong>CLA</strong>MP)<br />

is to promote public safety to the<br />

various user groups of Candlewood Lake<br />

and Squantz Pond. The <strong>Patrol</strong> provides a<br />

wide variety of services to the five towns<br />

and the boating public such as: information<br />

dissemination, boater education programs,<br />

emergency response to boating accidents,<br />

support to local law enforcement involving<br />

water related incidents, enforcement of CT<br />

Boating laws, Boating Safety Regulations<br />

and pollution laws.<br />

In addition to providing the services described<br />

above, the patrol deploys several types of<br />

specialty patrols. These special patrol details<br />

include Safety Inspections, the annual Firework<br />

Display, Sound Meter Inspections, Head<br />

Inspections, EMPD’s (Early Morning <strong>Patrol</strong><br />

Details), and the JSTF (Jet Ski Task Force)<br />

SAFETY PATROLS: With public safety<br />

being the main initiative for the <strong>CLA</strong>MP,<br />

we continued to conduct random Safe<br />

Boating Inspections throughout the season.<br />

During these inspections, our Lake <strong>Patrol</strong><br />

Officers interact with the majority of the<br />

boating public recreating on the lake<br />

during this scheduled detail. Our Officers<br />

carefully inspect the required safety<br />

equipment on board the vessel as well<br />

as the required vessel and operator<br />

documents/documentation.<br />

FIREWORK DISPLAY: The Danbury<br />

Volunteer Fire Department Council once<br />

again sponsored the annual fireworks<br />

display. The <strong>Patrol</strong> supplied 7 Vessels and<br />

17 Officers to help maintain public safety<br />

during this holiday display. <strong>Patrol</strong>s began<br />

as early as 10:00 am and ended the detail<br />

early the next morning.<br />

SOUND METER INSPECTIONS: We continued<br />

to experience success in enforcing the<br />

decibel limit (sound) law on the lake. This<br />

year, as in past, we received reports and/or<br />

complaints of loud boats, which contribute<br />

to the environmental pollutants on the lake.<br />

This year 6 vessels were inspected for sound.<br />

TOP 10 BOATING VIOLATIONS<br />

1. Light Violations<br />

2. Registration Violations<br />

3. Personal Floatation Device<br />

4. Operation a vessel within 100' of a<br />

shore / dock / swim area / launch<br />

5. Failure to display the Registration Decal<br />

6. Creating a wake within 200’ of the<br />

shoreline with a PWC<br />

7. Failure to Carry Certificate of PWC<br />

Operation or a Safe Boating Certificate<br />

8. Operation without a Safe Boating<br />

Certificate or a Certificate of PWC Operation<br />

9. Bow Riding<br />

10. Fire Extinguisher, Failure to have<br />

HEAD INSPECTIONS: We allocated manpower<br />

this year to performing dye tests in randomly<br />

selected <strong>Marine</strong> Sanitary Devices (MSD’s).<br />

Our goal during this detail is to remove<br />

malfunctioning MSD’s from the water. To<br />

date we have not found any MSD’s to be<br />

defective or have their switching/locking<br />

mechanisms tampered.<br />

CANDLEWOOD LAKE NEWS<br />

<strong>CLA</strong> <strong>Marine</strong> <strong>Patrol</strong> — Serving the Public since 1972<br />

Annual Report of Candlewood Lake Authority<br />

EMPD’s (Early Morning <strong>Patrol</strong> Details):<br />

We continue to deploy patrols during the<br />

early morning hours in an effort to have law<br />

enforcement presence on the lake during<br />

these busy times. This year we estimate<br />

that we invested approximately 75 manhours<br />

patrolling the waters during the early<br />

morning hours.<br />

JSTF (Jet Ski Task Force): The JSTF was<br />

new for us this year. Conceptually, Chief<br />

Yedowitz envisioned introducing a new tool<br />

to the patrol which would enable LPO’s to<br />

experience a higher level of contacts with the<br />

boating public, which inevitably would lead<br />

to more opportunities to promote boating<br />

<strong>CLA</strong>’s Year in Review—One for the ages!<br />

Certainly, the year’s biggest story was<br />

the development of the Shoreline<br />

Management Plan. Nothing in recent<br />

memory has gained the attention of the lake<br />

community like the SMP, and nothing in<br />

recent memory has evoked the level of<br />

involvement of the <strong>CLA</strong> board like the SMP.<br />

In addition to countless hours researching and<br />

studying a vast array of SMP-related<br />

information, including case studies of other<br />

FERC projects, the <strong>CLA</strong> participated in<br />

numerous stakeholder meetings and<br />

workshops through out the year. Northeast<br />

Generation Company, the owner of the lake at<br />

that time, held several<br />

public forums during the<br />

year, all of which the<br />

<strong>CLA</strong> participated in. The<br />

<strong>CLA</strong> tirelessly reviewed<br />

hundreds of pages of<br />

draft plans and<br />

correspondences to and<br />

from FERC, constantly<br />

apprising the Mayors<br />

and First Selectmen of<br />

the Candlewood towns<br />

on our findings from<br />

those reviews and from<br />

the research conducted.<br />

We also authored many<br />

letters expressing our<br />

concerns and views on how the plan could be<br />

improved. All of those documents are<br />

available online at<br />

www.candlewoodlakeauthority.org. In<br />

September of 2006, NGC submitted their plan<br />

to the Federal Energy Regulatory Commission.<br />

You can read the Shoreline Management Plan<br />

submitted to FERC at<br />

www.essexpartnership.com/<br />

documents.asp.<br />

Shortly after the submittal we learned of the<br />

year’s next biggest story – the sale of<br />

Candlewood Lake and the other reservoirs<br />

associated with the Housatonic Hydroelectric<br />

facilities. After six years under NGC’s<br />

ownership and many, many years under<br />

CL&P’s, the parent company of both<br />

subsidiaries – Northeast Utilities – decided to<br />

sell these generating assets. In early<br />

November, Energy Capital Partners acquired<br />

Candlewood and the rest of Housatonic<br />

Hydro. ECP created a holding company that<br />

is now known as FirstLight Power Resources,<br />

Inc. Now FirstLight and the entire lake<br />

community anxiously await FERC’s decision<br />

on the SMP. In the mean time, the <strong>CLA</strong> and<br />

many elected leaders of our communities had<br />

an opportunity to meet with the new FirstLight<br />

CEO, Curtis Morgan. While there are still a<br />

number of issues where a community-wide<br />

consensus has not been reached, most that<br />

have met Mr. Morgan were encouraged by his<br />

directness, his expressed<br />

willingness to work with<br />

the community, and his<br />

message that FirstLight<br />

is going improve its level<br />

of protecting the Lake.<br />

The top environmental<br />

story was the Eurasian<br />

watermilfoil and more<br />

precisely, the<br />

ineffectiveness of two<br />

consecutive deep winter<br />

drawdowns in killing<br />

back the exotic, invasive<br />

species. For years and<br />

years the deep<br />

drawdown, normally conducted every other<br />

year, sufficiently kept the weeds from reaching<br />

epidemic proportions. But in recent years,<br />

dense beds of the plant have choked areas<br />

around the edges of the lake despite the deep<br />

drawdowns conducted consecutively in the<br />

winters of 2004-2005 and 2005-2006.<br />

Another deep drawdown was performed this<br />

past winter (2006-2007) following an early<br />

October meeting of the Technical Committee,<br />

which the <strong>CLA</strong> and the CT DEP sit on to<br />

advise the power company on weed-related<br />

issues. Obvious questions still in need of<br />

answers are 1) why haven’t the drawdowns<br />

worked in recent years, and 2) if they continue<br />

to be ineffective, then what? On page 6 look<br />

for more information on what the <strong>CLA</strong> and<br />

others are doing to better understand the<br />

weed issues.


Boat Count Account—Resident Numbers Stable<br />

Each year the <strong>CLA</strong> spends time determining the numbers of seasonally moored or docked vessels. These do not include vessels that use the<br />

vast number of public or private ramps where boats are launched, used for recreation and pulled out in the course of a day or two.<br />

Currently, there is no accurate way of measuring use on Candlewood by day-boaters.<br />

The <strong>CLA</strong> has collected this data for many years and by looking at the long term data in the figure below one sees rapid growth in numbers<br />

of non-cabined boats up through the mid to late 1980s. Growth in the other categories is not quite as pronounced and very gradual at best.<br />

Total vessel numbers for 2004, 2005, and 2006 is 5962, 5796, and 5945, respectively, indicating stability in resident numbers.<br />

Methods of collecting data are evolving to better understand the recreational boating picture on the Lake. The figure to the right provides a<br />

first approximation of the distribution of registered boats (vessels with engines, PWCs, larger sail boats) permanently on the lake. The chart<br />

was developed using the last two years of boat count data. There were some inconsistencies between years, particularly with the<br />

community marina boats because of difficulties in identifying small community marinas.<br />

At the request of local government leaders, the <strong>CLA</strong> is developing a Boat Sticker Program, which will be brought back to government<br />

leaders for their consideration. One of the benefits of the program will be the ability to collect better information on the recreational boating<br />

use of Candlewood.<br />

JMM Lake Clean Up<br />

The Eighth Annual John Marsicano Memorial Candlewood Lake<br />

Clean Up took place on May 13th. Nearly 250 community<br />

volunteers participated including members from twelve<br />

community service groups, who removed enough garbage from the<br />

undeveloped shores of the lake to fill two large dumpsters. The<br />

amount was estimated to be between 8 and 10 tons. Forty local<br />

business sponsors and fourteen lunch sponsors also helped make<br />

the event the success that it was. As has been the tradition, New<br />

Fairfield Park & Rec office provided the site for the lunch and<br />

assistance from their Public Works Department.<br />

Last year, a group of volunteers emerged to help organize and plan<br />

the event. Led by Bob Groeschner and Vin Iovino of the Candlewood Lake Club Community, these lake loyalists also created a report<br />

documenting each of the steps that go into the planning of the event. This report will become very important in the future as others plan<br />

the event. If you are interested in helping in the planning in coming years, contact our office.<br />

Water Quality 2006: Report Available Online<br />

The <strong>CLA</strong> monitors the water quality of the Lake each season and has done so since<br />

1983. Secchi disk transparency, chlorophyll levels, and nutrient (total phosphorus and<br />

total nitrogen) concentrations are water quality characteristics used to classify the<br />

trophic level of a lake. The trophic level refers to amount of productivity, usually algae<br />

growth, which a lake can support. Nitrogen and phosphorus are often referred to as limiting<br />

nutrients, in that they are the least available and therefore can regulate how much algae or<br />

plant growth will be supported.<br />

Chlorophyll concentrations provide insights into the growth of the phytoplankton, or algae<br />

that live in a floating state in the water. Both the nutrients and chlorophyll are determined<br />

from samples collected in the field and analyzed in the laboratory. Secchi disk<br />

transparency, on the other hand, is measured in the field by lowering a 20 cm, black and<br />

white Secchi disk into the water and finding the exact depth at which visual contact is<br />

lost. These parameters are related in that the nutrients can regulate the algae growth,<br />

which in turn can influence how far down into the water column someone can see.<br />

By regressing average chlorophyll against average Secchi transparency year to year and<br />

plotting those points, we can see how closely related those two characteristics are to each<br />

other and we can also compare water quality year to year. Most of the points along the<br />

regression line fall somewhere in the middle and represent typical years. Points at the<br />

extremes of the line represent years that may be atypical. This past year was one of those<br />

atypical years with low chlorophyll concentrations and high Secchi transparency.<br />

Curiously, total phosphorus levels where, on average, high – this contradicts what is<br />

being inferred from chlorophyll and Secchi transparency data.<br />

The reason for the contradiction is not readily understood at this time. It may be related<br />

to the lush growth of the aquatic weeds this year. The weeds can act as both a nutrient<br />

sink and source, sometimes absorbing nutrients from the water, sometimes releasing<br />

them. We will continue to closely monitor the water quality and analyze the results.<br />

There are also future efforts to measure the level of weeds year to year. This will aid in a<br />

better understanding of the water quality – aquatic weed relationship in the future.<br />

Results from the monitoring efforts over the last four years are available at the <strong>CLA</strong><br />

website in pdf format.<br />

Administrative &<br />

Operational Information<br />

The Board of the <strong>CLA</strong> is comprised of<br />

Delegates who voluntarily serve terms<br />

of three years. Three Delegates are<br />

appointed by each of the Chief Elected<br />

Officials from Brookfield, Danbury, New<br />

Fairfield, New Milford and Sherman. Each<br />

Delegate attends meetings and works in<br />

committees to advance the mission of the<br />

<strong>CLA</strong>. Standing Committees include<br />

Executive, Finance, Equipment/Facilities,<br />

Public Safety, Public Awareness and<br />

Watershed. There are several<br />

subcommittees and ad hoc committees.<br />

The budget of the <strong>CLA</strong> is the responsibility<br />

of the five member municipalities. It is<br />

determined though the financial processes<br />

of each of the five municipalities. The three<br />

budgets approved by the municipalities that<br />

are closest to the proposed budget are<br />

averaged. That average is the appropriation<br />

for each municipality. The power generating<br />

company, now FirstLight Power Resources,<br />

has also contributed on a voluntary basis a<br />

sum equal to that appropriated by each<br />

municipality.<br />

The business office of the <strong>CLA</strong> is located at<br />

20 Sawmill Road in Sherman, CT in the<br />

Sherman Town Beach area. The office itself<br />

is a converted cabin that was formerly part<br />

of the Allen’s Camp and is owned by the<br />

Town of Sherman who leases it to the <strong>CLA</strong><br />

at no cost through an agreement made over<br />

25 years ago. Since it is a stand alone office<br />

and since the <strong>CLA</strong> does not operate under<br />

any one local jurisdiction, but rather five,<br />

staff does not benefit from common<br />

programs (e.g., health benefits) or office<br />

resources (e.g., IT assistance, cost-sharing<br />

of office supplies, maintenance, etc.), that<br />

might be shared by various departments in a<br />

town or city hall.<br />

The <strong>CLA</strong> also maintains docks in front of the<br />

office where their fleet of five boats often<br />

reside during the recreational boating<br />

season (typically April through October).<br />

Two of the vessels are used exclusively for<br />

lake patrol work. One is used by<br />

administrative, operational, and by lake<br />

patrol staff as needed. Another is a work<br />

vessel used for deployment, maintenance,<br />

and removal of buoys and also acts as an<br />

onboard classroom for educational<br />

programs the <strong>CLA</strong> provides. This vessel was<br />

not purchased but rather built by Danbury<br />

Delegate Ed Siergiej in 2002.


Partnerships: Building a Better Lake Community<br />

The <strong>CLA</strong> is fortunate to have a number of<br />

contributors to its efforts to protect the<br />

Lake. We continue to benefit from longstanding<br />

relationships with agencies like the<br />

Connecticut Department of Environmental<br />

Protection, the Housatonic Valley Council of<br />

Elected Officials and the Housatonic Valley<br />

Association, all of which work in the interests<br />

of much larger areas than just the lake or its<br />

watershed. In recent years we have benefited<br />

from developing deeper relationships with the<br />

following:<br />

Education Connection – While the <strong>CLA</strong> still<br />

plays a key role in Project CLEAR, EC has<br />

become the primary organizational and<br />

administrative component of CLEAR. It is<br />

EC that writes the grants that provide the<br />

funding that allows the program to be as<br />

successful as it is. CLEAR’s Project<br />

Manager is Tom Adams of EC who has done<br />

a tremendous job orchestrating the various<br />

components of CLEAR and has brought a<br />

new technology component to CLEAR<br />

making it even more so a real training<br />

ground for college level education. See<br />

www.educationconnection.org to learn<br />

more about EC.<br />

Northwest Conservation District – The NCD<br />

has a long history of helping communities<br />

better protect important natural resources.<br />

The <strong>CLA</strong> has greatly benefited from its<br />

relationship with them. They have been<br />

involved in land use and storm water man-<br />

<strong>CLA</strong> <strong>Marine</strong> <strong>Patrol</strong> (continued from page 1)<br />

safety. In addition, this new tool would enable the <strong>CLA</strong>MP to launch<br />

more patrols on Squantz Pond.<br />

The JSTF was immediately a success. Our LPO’s worked in tandem,<br />

patrolling shorelines, boat launches, marina’s and many of the tight,<br />

secluded areas on the lake that may not be accessible to our<br />

standard patrol boats. The JSTF was actually an addition to our<br />

regularly scheduled patrols, so in essence it added two (2) additional<br />

LPO’s on the water during the busy weekend days.<br />

Our contacts with the public were high due to our ability to navigate<br />

more effectively and swiftly in shallower waters and in tighter areas.<br />

We were easily able to approach groups of “rafting” boats, often<br />

from two opposing ends, which enabled us to make contact with a<br />

greater number of operators in a shorter amount of time.<br />

The patrol looks forward to a safe 2007 boating season!<br />

agement issues around the lake. They have<br />

also greatly assisted the <strong>CLA</strong> with the<br />

development of its GIS capabilities<br />

(see page 7). For more information on their<br />

programs, see www.conservect.org/<br />

northwest.<br />

Connecticut Agricultural Experiment Station<br />

Like the NCD, the CAES is a publicly funded<br />

organization. CAES is involved in a wide<br />

variety of environmental research including<br />

studies on invasive aquatic plants like<br />

milfoil. In addition to participating in the<br />

Project CLEAR program, they have<br />

conducted research on Candlewood over<br />

the last several years. See page 7 to learn<br />

about those efforts and for a link to their<br />

website.<br />

Western Connecticut State University<br />

The <strong>CLA</strong>’s relationship with WCSU is<br />

certainly not new… the water quality<br />

monitoring program was started by faculty<br />

researchers at the University back in the<br />

early 1980s! But in recent years, our<br />

relationship has blossomed again. For<br />

example, WCSU provides classroom and<br />

computer lab space for the Project CLEAR<br />

students through out the year. Several of<br />

the current faculty members are meeting<br />

with the <strong>CLA</strong> to develop research initiatives.<br />

The <strong>CLA</strong>’s current intern came by way of<br />

one of the faculty we collaborate with. We<br />

are fortunate to have a nearby University so<br />

interested in the environmental, political and<br />

social issues surrounding the lake.<br />

Greater Danbury Chamber of Commerce<br />

One of the difficulties the <strong>CLA</strong> has always<br />

had in obtaining grants and foundation<br />

money was that it was not a 501(c)3<br />

nonprofit organization, even though<br />

contributions to the <strong>CLA</strong> are tax deductible.<br />

The GDCC has graciously remedied that<br />

problem by voting to bring us under the<br />

umbrella of their Western Connecticut<br />

Business and Industry Community<br />

Foundation. This will expand our base of<br />

potential grant and foundation money<br />

opportunities. For more on the GDCC, go to<br />

www.danburychamber.com. We look<br />

forward to building on our relationship with<br />

the Chamber and with all our partners.<br />

Bacteria Monitoring Program<br />

NFSEC Gets “Techno-savy”<br />

For their second straight year, the New Fairfield Seniors<br />

Environmental Corps conducted the <strong>CLA</strong>’s Bacteria Monitoring<br />

Program. Each week from June through August, members from<br />

the New Fairfield Senior Center drove the entire perimeter of the<br />

lake collecting water samples at selected locations and delivered<br />

them to Hydro-Technologies, a state certified environmental lab,<br />

for bacteria analysis. The vast majority of the samples collected<br />

revealed safe conditions at those sites. When bacteria levels<br />

exceeded State standards, towns and/or communities where the<br />

sample was collected were notified and advised to retest.<br />

This past season the NFSEC used global positioning systems or GPS<br />

to determine the exact coordinates or location where samples were<br />

being collected. GPS coordinates were uploaded into a Geographical<br />

Information System (GIS) system so they could be precisely<br />

represented on a map. Results from bacteria monitoring program<br />

can be found in the 2006 Monitoring report at the <strong>CLA</strong> website.<br />

Invasive Milfoil: Can it be Controlled? Past and Future Efforts<br />

Many had characterized the last several seasons as having some<br />

of the worst weed conditions ever. And if that’s not bad<br />

enough, then consider that those seasons followed deep<br />

winter drawdowns that normally would kill back excessive growth<br />

the following season. Since the early 80s, the power company<br />

operating Rocky River has lowered the level of the lake by<br />

approximately 10 feet every other winter to manage the growth of<br />

Eurasian watermilfoil. The every-other-year approach was<br />

determined by a Technical Committee, comprised of environmental<br />

scientists concerned about both the weeds and also the negative<br />

impacts of deep drawdowns on the rest of the lake’s fauna and flora.<br />

By and large, the method was considered effective. Then several<br />

years ago the lake began to experience severe infestations regardless<br />

of the type of drawdown the winter before. Had the weeds become<br />

more resistant to the cold? Were winter conditions different than in<br />

the past? We could only theorize due to the lack of data being<br />

collected.<br />

One of the lesser known management plans required in the FERC<br />

license is the Nuisance Plant Monitoring Plan. Conditions in this<br />

plan, conditionally approved by FERC in February of 2006, are that<br />

the weeds in Candlewood, Lillinonah, and Zoar will be mapped<br />

annually by FirstLight Power Resources, Inc. By doing so and by<br />

collecting other associated data, like winter weather conditions,<br />

water quality, and lake level, scientists should be able to begin<br />

piecing together a more in-depth understanding of why deep<br />

drawdowns work some years and don’t work in others.<br />

Over the last several years, the <strong>CLA</strong> has been collaborating with<br />

the Connecticut Agricultural Experiment Station on this issue. Led<br />

by Greg Bugbee and his team of researchers, the CAES has mapped<br />

invasive aquatic plants in lakes throughout Connecticut and has<br />

emerged as one of the leading groups in the State working on this<br />

environmental issue. To learn more about aquatic invasive weeds in<br />

the State and the efforts of CAES, go to www.caes.state.ct.us/<br />

AquaticPlants/index.htm. CAES has accurately mapped the weeds<br />

in Candlewood over the last two seasons. The results of their<br />

mapping efforts on Candlewood are also available on the web at our<br />

website in a downloadable report produced by the <strong>CLA</strong> on<br />

alternative methods to managing nuisance aquatic weeds. The title<br />

Enchanted Evening on the Lake – Fundraiser a Huge Success<br />

On Friday, April 27th the <strong>CLA</strong> held its<br />

first Enchanted Evening on the Lake<br />

dinner / auction fundraising event at<br />

the Candlewood Inn in Brookfield. By all<br />

accounts, the evening was an overwhelming<br />

success with many of the attendees<br />

suggesting that this should become an<br />

annual event.<br />

The fundraiser was held to raise money for<br />

the proposed Candlewood Lake Education<br />

and Resource Center (CLERC). Several<br />

years ago the City of Danbury designated<br />

portions of a bond initiative to create the<br />

CLERC. The <strong>CLA</strong> committed to raising the<br />

funds to furnish the inside with office<br />

furniture, audio-visual equipment,<br />

Fundraiser Committee Chairman Glenn Hofsess holding<br />

one of the live auction items – a Les Paul Gibson guitar<br />

signed by the legendary Les Paul, himself.<br />

information technology, educational<br />

materials, and other items to help make the<br />

new facility a place the community would<br />

visit to learn about the lake.<br />

Management Considerations<br />

and Possible Alternatives to the<br />

Deep Drawdown.<br />

In March of 2007, a Technical<br />

Committee met with FirstLight<br />

to discuss the results of some<br />

mapping efforts by a consulting<br />

firm they hired. Members of<br />

the Committee attending<br />

included the CT DEP, and the<br />

Lake Authorities from<br />

Candlewood, Lillinonah and<br />

Zoar. The consultant used a<br />

predictive modeling approach<br />

to map the weeds which did not meet the approval of members of<br />

the Committee. The CAES also attended the meeting and shared<br />

the results of their actual mapping, as well as their thoughts on<br />

using remote sensing in the future to map the weeds. The <strong>CLA</strong><br />

and CAES had been discussing this technique prior to the meeting<br />

and believe it should be explored. FirstLight has agreed to<br />

purchase aerial flyover data this summer to see if it will provide a<br />

cost-effective and accurate means of mapping the weeds annually<br />

in all three lakes. The <strong>CLA</strong> asked FirstLight that the CAES be<br />

allowed to lead the efforts to map the weeds on Candlewood and<br />

the other impoundments. FirstLight has contracted with the CAES<br />

for weed mapping this upcoming season.<br />

The <strong>CLA</strong> is also exploring a biological control of milfoil with the<br />

CAES. Dr. Michelle Marko from CAES is an expert on the milfoil<br />

weevil, which is an insect that lives in lakes and if at high enough<br />

population densities can also control the spread of milfoil. The<br />

small aquatic insects feed specifically on the aquatic plant.<br />

Preliminary studies on Candlewood have verified the presence of<br />

the weevil but not nearly at the levels needed to control the milfoil.<br />

Dr. Marko, Dr. Mitch Wagener from WCSU, and the <strong>CLA</strong> will be<br />

meeting in the near future to plan out research to investigate the<br />

feasibility of increasing the populations of the weevils in<br />

Candlewood. One of the challenges will be finding funding to<br />

jumpstart the project. Private sponsorship is being sought for this<br />

purpose – interested individuals should contact the <strong>CLA</strong> office.<br />

The Candlewood Inn provided exquisitely<br />

prepared food and beverages and the Bock<br />

and Blue Jazz Trio provided music. Most of<br />

the activities, however, were centered around<br />

the over 150 silent and live auction items on<br />

display. There were a wide variety of auction<br />

items including art, jewelry, sports<br />

memorabilia, experiences and services.<br />

Bidding on the items was lively and often<br />

entertaining.<br />

The <strong>CLA</strong> wishes to express its sincerest<br />

appreciation to all that made the event the<br />

success it was including sponsors, auction<br />

item donors, those attending the event, and<br />

the Event Committee and staff of the <strong>CLA</strong><br />

who organized the gala.


Shoreline Management: New Tools for an Old Job<br />

Part of a successful lake management<br />

program is helping the community<br />

protect the environmental values of the<br />

shoreline and near lake areas. For years we<br />

have provided eyes and ears on the lake to<br />

assist land use agencies with regulations<br />

pertaining to uses of those lands. In more<br />

recent years we have been asked to provide<br />

written observations and recommendations<br />

at sites found to be exceeding local<br />

standards. The figure to the right shows the<br />

location of the sites we assisted on during<br />

this and the past year.<br />

The <strong>CLA</strong> is also developing technology to<br />

manage information about the shoreline.<br />

GIS – or geographic information systems –<br />

is a recent advancement in the management<br />

of spatial and temporal data using a<br />

graphical interface. So on the <strong>CLA</strong> GIS for<br />

instance you can retrieve aerial flyover<br />

photos of a section of the lake, overlie the<br />

parcel boundaries, pull up owner<br />

identification information, and an image of<br />

shoreline conditions as of 2006. Future<br />

plans include providing tools for local land<br />

use enforcement officers to access the data<br />

as well. GIS will also become an important<br />

component of understanding the<br />

distribution and success or lack of success<br />

of weed management. Look for more on<br />

this new tool in the future newsletters.<br />

Short Notes<br />

Grant Proposal to create<br />

Buffer Assistance Program<br />

As part of the settlement agreement for<br />

damages to the Housatonic River from<br />

PCB pollution, General Electric created<br />

an environmental restoration fund in CT,<br />

which is worth about $9 million. To<br />

administer these funds, a Natural Resource<br />

Trustee SubCouncil for CT was formed, and<br />

is comprised of representatives from the CT<br />

DEP, the US Fish and Wildlife Service and<br />

from the National Oceanic and Atmospheric<br />

Administration. The SubCouncil created a<br />

process by which organizations could apply<br />

for portions of those funds to mitigate<br />

environmental and recreational damages<br />

caused by the PCB contamination. The <strong>CLA</strong><br />

submitted one of 92 pre-proposals received<br />

by the SubCouncil. The <strong>CLA</strong>’s proposal was<br />

for funding to create a matching grant<br />

program to aid property owners abutting<br />

Candlewood, Lillinonah or Zoar who want to<br />

install a riparian buffer along the shores of<br />

the lakes to protect water quality and<br />

provide habitat.<br />

The SubCouncil’s grant process has two<br />

parts: first is an eligibility screening; second<br />

is a project evaluation. The <strong>CLA</strong>’s proposal<br />

passed the eligibility screening with<br />

conditions. Supplemental information will<br />

be requested and submitted in the near<br />

future. The <strong>CLA</strong>’s pre-proposal can be read<br />

on their website as well as<br />

www.housatonicrestoration.org where<br />

more information on the Housatonic<br />

restoration program can be found.<br />

CLEAR Continues to Exceed<br />

Expectations<br />

High School Students to pass<br />

message to middle schools<br />

The Project CLEAR program continues to<br />

be popular among the high school<br />

students around the lake. Last year<br />

another group of 100+ students participated<br />

in several days of classroom activities, the<br />

Candlewood Clean Up, and a week of<br />

freshwater environmental “research camp”<br />

where they divided into several teams and<br />

studied various aspects of the ecology of the<br />

lake. Teams studied water quality, milfoil and<br />

a native insect that eats it, fish communities,<br />

and conditions of the watershed, shoreline,<br />

streams draining to the lake, and forest<br />

community on the islands and Vaughn’s<br />

Neck. Another group of 125 students are<br />

involved in the program this year as well.<br />

In addition, a number of the last year’s<br />

graduating CLEAR participants have<br />

received educational and leadership training<br />

from environmental educators at the CT<br />

DEP. They will be using those skills by<br />

providing activities and programs for middle<br />

school students in their own school<br />

districts. Their efforts will help the Project<br />

CLEAR program make its goal of integrating<br />

the program into those grade levels.<br />
