Each year dedicated members of the Truesdale Lake community (Gary Struve and Debbie Fink) take water samples and record observations on Lake Truesdale. Quote:

Released August 2005, the latest CSLAP (Citizen's Statewide Lake Assesment Program) Report for Truesdale Lake for calendar year 2004. Run in conjunction with NYSFOLA and New York State DEC. Water sampling performed locally by volunteers Debbie Fink and Gary Struve.

BACKGROUND AND ACKNOWLEDGMENT

The Citizens Statewide Lake Assessment Program (CSLAP) is a volunteer lake monitoring program conducted by the NYS Department of Environmental Conservation (NYSDEC) and the NYS Federation of Lake Associations (FOLA). Founded in 1986 with 25 pilot lakes, the program has involved more than 200 lakes, ponds, and reservoirs and 1000 volunteers from eastern Long Island to the Northern Adirondacks to the western-most lake in New York, and from 10 acre ponds to several Finger Lakes, Lake Ontario, Lake George, and lakes within state parks. In this program, lay volunteers trained by the NYSDEC and FOLA collect water samples, observations, and perception data every other week in a fifteen-week interval between May and October. Water samples are analyzed by certified laboratories. Analytical results are interpreted by the NYSDEC and FOLA, and utilized for a variety of purposes by the State of New York, local governments, researchers, and, most importantly, participating lake associations. This report summarizes the 2005 sampling results for Lake Truesdale.

Lake Truesdale is an 83 acre, class B lake found in the Town of Lewisboro in Westchester County, in the Lower Hudson River basin of New York State. Lake Truesdale was first sampled as part of CSLAP in 1999. The following volunteers have participated in CSLAP, and deserve most of the credit for the success of this program at Lake Truesdale: Debbie Fink, Ray Morse, David Robinov,
Tricie Singer, and Gary Struve.

The Citizens Statewide Lake Assessment Program (CSLAP) is a volunteer lake monitoring
program conducted by the NYS Department of Environmental Conservation (NYSDEC) and the NYS
Federation of Lake Associations (FOLA). Founded in 1986 with 25 pilot lakes, the program has
involved more than 200 lakes, ponds, and reservoirs and 1000 volunteers from eastern Long Island to
the northern Adirondacks to the western-most lake in New York, and from 10-acre ponds to several
Finger Lakes, Lake Ontario, Lake George, and lakes within state parks. In this program, la y volunteers
trained by the NYSDEC and FOLA collect water samples, observations, and perception data every other
week in a 15 week interval between May and October. Water samples are analyzed by certified
laboratories. Analytical results are interpreted by the NYSDEC and FOLA and utilized for a variety of
purposes by the State of New York, local governments, researchers, and, most importantly, participating
lake associations. This report summarizes the 2006 sampling results for Lake Truesdale.
Lake Truesdale is an 83 acre, class B lake found in the Town of Lewisboro in Westchester
County, in the Lower Hudson River basin of New York State. Lake Truesdale was first sampled as part
of CSLAP in 1999. The following volunteers have participated in CSLAP, and deserve most of the

In addition, the authors wish to acknowledge the following individuals, without whom this
project and report would never have been completed:
From the Department of Environmental Conservation, N.G. Kaul, Sal Pagano, Dan Barolo, Italo
Carcich, Phil DeGaetano, Dick Draper, and Jeff Myers for supporting CSLAP for the past 20 years; Jay
Bloomfield and James Sutherland, for their work in developing and implementing the program, and the
technical staff from the Lake Services Section, for continued technical review of program design.
From the Federation of Lake Associations, Anne Saltman, Dr. John Colgan, Don Keppel, Bob
Rosati, Don Cook, Nancy Mueller and the Board of Directors, for their continued strong support of
CSLAP.
The New York State Department of Health (prior to 2002), particularly Jean White and Upstate
Freshwater Institute (since 2002), particularly Steve Effler and Jennifer Aicher, provided laboratory
materials and all analytical services, reviewed the raw data, and implemented the quality
assurance/quality control program.
Finally, but most importantly, the authors would like to thank the more than 1,000 volunteers
who have made CSLAP a model for lay monitoring programs throughout the country and the recipient
of a national environmental achievement award. Their time and effort have served to greatly expand the
efforts of the state and the public to protect and enhance the magnificent water resources of New York
State.

Engineering Plans for Truesdale Lake Dam Repair. Completed February 10, 2004 by HTE Northeast.

Initial Study performed by Land-Tech Consultants (www.landtechconsult.com) in 2001. Contains information about the six "hotspots" where sedimentation and runoff are of the greatest concern.

Lakes Management Plan
In August 2007, EcoLogic entered into an agreement with the Town of Lewisboro to develop a planning document outlining management of the lakes and watershed areas within the Town.

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.
