Deer Lake Fly-Over
On June 24th, 2006, Al Cibizar from A. W. Research Labratories presented the results of the "Fly-Over" conducted last Fall. It was a fascinating program and of great interest to the health of the lake. The focus of the study was to identify potential sources of pollution around the lake, most notably coming from septic systems, but also from other sources. General details of the health of Deer Lake will be posted here soon. In addition, each property owner will receive a confidential report on their own situation, with recommendations for correction if necessary. One bit of advise can apply to everyone: the single most effective and easiest thing we can all do is to retain a shoreland buffer between our yards and the lake. This is as simple as a no-mow zone at least for the first 10 feet back (with a path access to dock and beach). This will prevent the rain runoff from going directly into the lake, filtering debris and nutrients, and keeping the lake clean.
Here is a picture of the well attended June 24 meeting:
The purpose of this report is to update you on the progress of the photographic survey of the lakeshore analysis begun last fall by the
Many have said that what they appreciate most about
Of course each of us are primary stewards of the lake will want to be aware of this and do all we can to preserve and improve its water quality. There are also some things we can do best together. With this in mind the DLA has adopted the ambitious goal of improving the lake's clarity by 3 feet in the next 20 years (per the Secchi disc reading). It is difficult but doable according to the three limnologists (specialists in lake quality) lake resident who advice the board. This 3 in 20 program will require cooperation and participation of all of us.
High phosphorus, septic seepage and sediment levels are the three major factors contributing to the decline in lake water quality. Accordingly, the DLA Board commissioned the lakeshore analysis to determine the levels and areas affected and to create a historical data base for comparison in monitoring future lake conditions. It will provide information about how each of us effects the environment as well as what we can volunteer to do as property owners to help preserve the quality of our lake.
It’s Hi-Tech! Two photographic flyovers were done this fall using visual and infrared ektachrome 35 mm films and hyper spectral video consisting of chlorophyll A, water penetrating near IR and thermal imaging techniques. During the winter this will be analyzed for the extent of eutrophication (process by which a lake receives excess nutrients that stimulate excessive plant growth-algae bloom, etc.) with respect to aquatic vegetation and several categories of possible nutrient or toxic sources such as septic leakage, fertilizer runoff, and certain land use practices.
The results of the survey will be presented early this summer in the following manner;
1. An oral and video presentation giving the overall status of the lake, open to all lake residents.
2. Data on each property will be given separately and confidentially to each owner free of charge with suggestions for necessary improvements, where needed. Any action resulting from the survey will be individual and voluntary.
We believe this survey will enhance our understanding of the importance of preserving our lake's quality and guide our efforts toward perpetuating our enjoyment of it in the future.
The cost of this analysis, while substantial, is a fraction of what individual property inspections would cost. Financial support was provided from the DLA Endowment and Preservation Fund which supports projects that benefit the lake's water quality. It is separate from the DLA general fund which is supported by annual dues.
