Comments: Curlyleaf pondweed was dying off, however, leafy pondweed was not yet showing signs of Sonar damage. Filamentous algae covered 50% of the surface in the southwest beach. After motoring over it, the algae was submerged and occupied less than 10% of the surface. Two FasTEST samples were taken, sample A from the north (outlet), Sample B from the southern end. The aeration system filter and four stones on each of the 3 diffusers were replaced, and the diffusers were repositioned in a straight line along the south rope.
TRUESDALE LAKE SUNFISH RACING SCHEDULE 2009
SUNFISH FLEET #27
OBJECTIVE
The prime objective of our racing series is to have fun and encourage us all to leave our lawn maintenance, desk work and other chores and spend some time out on our beautiful Truesdale Lake.
SCHEDULE
A summer Sunfish series of 20 races will be held, with 2 races each Sunday, the first beginning at 1:30 p.m. Practice & fun races will be held in June. The regular series on the 10 Sundays from June 28- August 30. (“President’s Cup special race on 9/6) Since we only count your best 10 races, you can win the series, and still miss 1/2 the races. If sufficient boats participate- two fleets will compete allowing beginners an easier learning experience otherwise beginners will also be given early starts and minimal rule enforcement.
SPECIAL EVENTS:
Summer Sailstice fun races & warm up Saturday June 20: 1:30pm; non-racers welcome
Sign up at http://www.summersailstice.com for a chance to win prices and/or buy T-shirts etc.
Full Moon regatta Sunday July 5, 8:45pm (all boats welcome – put a lantern on your dock)
TROPHY
The winner keeps the fleet trophy for a year.
SERIES RULES
Two official races will be run each Sunday. A race will be canceled if no boat finishes within one hour of the start. The winner of the series will be determined by adding up the scores for each boat's best 10 races out of a possible 20. Ties will be broken by counting the number of firsts.
SCORING
1 point for starting (register with race committee),

Each spring at the lake edges you will see signs of Sunfish spawning. The sunfish create circular 'nests' by fanning away debris and exposing the rocks or sand below. They aggressively defend these nests from others in the water, including humans. If you have ever been wading in the water of Truesdale Lake and been rammed in the legs by a sunfish when you get too close to their nest you will know what I mean. They look small but you will be in for a surprise when they swim into your legs.
Another spring and early summer sight is dead sunfish along the bank. Based on information from the Connecticut DEP, we can say that this is a natural part of the sunfish life cycle, affecting the weaker fish during and after spawning.
from the story here:
Quote:
The state Department of Environmental Protection and the city said the problem appears to strictly involve sunfish, noting there are other fish, birds and turtles at the pond showing no ill effects. The DEP said that happens every year in New Britain and other parts of the state, to varying degrees, because it's the spawning season for the species.
"The sunfish have a virus or bacteria when they spawn," Parks and Recreation Commission Director Bill DeMaio said. "I'm told that they don't eat properly and they become less healthy, just like human beings would be if you didn't eat, and they pass the bacteria to each other."
Fish deaths can also be caused in a number of other ways. Smaller fish can be chased into shallow water by larger predators and get stuck in weeds and unable to get free. Also, in warmer months, the oxygen levels of the lake go down as the water heats up. This causes the weaker fish to die off.
Truesdale Lake has tens of thousands of fish all different sizes. Our lake manager, Allied Biological, has said that dead fish are nothing to get alarmed about in small quantities (10+ on a typical waterfront) and are normal for lakes. However, if you notice dead fish in larger quantities (over 100) then there may be something else going on and please let us or Allied know.
The Lewisboro Lakes Report is available for download at this website by clicking on the Lewisboro Lakes link on the left hand side of this web page.
The materials available are the original report (from February 6, 2009) in its entirety as well as fact sheets for each of the seven lakes broken out. There is also the MS Access file available to download if you want to delve into the data.
The May 2009 presentation of the report to the Town Board and public is also available at the same link.
The Allied Biological boat will be out Monday, May 18th (weather permitting) for the first Truesdale Lake treatment of 2009.

From LoHud.com / The Journal News:
Quote:
The Westchester County Board of Legislators last night unanimously approved a ban on phosphorus and added restrictions on lawn fertilizers as a way of improving the region's water supply. The law basically regulates the use and sale of fertilizers...
...The aim is to reduce runoff of nitrogen and phosphorus into water bodies, such as the Hudson River and Long Island Sound, where they feed algae, which then blocks sunlight and consumes oxygen from the water that aquatic life needs to survive.
If you live in the lake watershed you should already be using phosphorus free fertilizer. Using phosphorus-based fertilizer contributes to weed and algae growth in our lake and also downstream. The soil in this region already has plenty of phosphorus.
There are other more environmentally sensitive fertilizers available at many local nurseries including Gossett Brothers on Route 35.
On May 7th at 7:30pm the firm EcoLogic, LLC of Cazenovia, NY will present the townwide lake study to the Town Board. The Town Board meeting for that evening is scheduled for 7:30PM at the Increase Miller School in Goldens Bridge. See the Town of Lewisboro website for more details and agenda.
History:
In August 2007, EcoLogic, LLC entered into an agreement with the Town of Lewisboro via the Lewisboro Lakes Committee to develop a planning document outlining management of the lakes and watershed areas within the Town.
The report will be available here when it is presented and accepted by the committee and the town (around 10Mb pdf file).
The zip file containing the MS Access database used for producing the charts, graphs, and analysis will also be available here. (2.5Mb est zipped size)[/url]
Four specific objectives were cited:
• Create a central repository of natural resource data, statistics, and testing data for each of the lakes in the Town;
• Summarize each lake’s water quality and environmental concerns;
• Recommend the most logical, environmentally sound, and cost-effective sequence of projects to improve and maintain water quality throughout the Town;
• Synthesize and collate all the studies on each of the lakes.
Additional data gathering and evaluation tasks were included to meet the overall objectives. This document – Town-Wide Comprehensive Lakes Management Plan - summarizes the water quality and aquatic habitat conditions of seven lakes in the Town of Lewisboro, and recommends measures for their protection and restoration.
Report Organization
The Town-wide Lakes Management Plan is organized in three sections. The first is composed of this introduction, a summary of the environmental settings of the lakes, followed by “Fact Sheets” for each lake. These fact sheets may be used as reference material for the lake associations. The second section discusses the water quality issues on a Town wide basis, identifies the pollutant(s) of concern and their source(s), and identifies reductions needed to meet restoration goals. The third and final section is a synthesis of management options and sets forth recommendations and priority actions for the Town of Lewisboro.

Each workshop will cover Canada Geese behavior, effective geese management techniques, case studies from other communities, federal and state regulations, and where to find additional resources. Speakers include:
David Feld, GeesePeace, Inc.
Bryan Swift, Game Bird Unit NYSDEC Bureau of Wildlife
Stacy Pecor Preusser, USDA Wildlife Services
This workshop is for property, school grounds, recreational facility and park managers, golf courses, college and corporate campuses, lake associations, homeowner associations, cemeteries, public health managers, and the interested public.
The workshops will provide valuable information that will prepare participants for action this upcoming spring.
The workshops are identical, so those interested need only register for one. The workshops are free but registration is required. See links above. Please register by March 16.
Because geese do not recognize property boundaries and so will nest on one property and cause a nuisance on another, it is important for neighboring properties to be aware of management techniques. We encourage you to invite your neighboring property owners to this event. Please forward this announcement.
