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 />
of the report is Eurasian Watermilfoil on Candlewood Lake:<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 />
