LAKE MANAGEMENT

The Copake Lake Conservation Society seeks to maintain the water quality and ecological balance of the lake and its surrounding area, as well as to provide educational programs that promote safety and conservation.

In keeping with our mission, the Lake Management Committee serves to plan and carry out the interventions required to maintain the vitality of the water, shoreline, and watershed in and around Copake Lake. The CLCS has established standards for critical factors such as lake clarity, lake chemistry, swimming safety, and invasive weed control. The LMC is responsible for the collection and analysis of relevant data,so that current conditions can be assessed against these standards. An annual lake management plan is then developed, which is directed toward maintaining long term water quality and ecological balance.

At our Annual Meeting on July 11, 2015, limnologist George Knoecklein gave a very informative presentation on the current condition of Copake Lake.

• Lake Level -- In order to protect the structures close to the shoreline from ice erosion and damage, we must draw down the lake level every winter. Because there is no way to refill the lake other than rain and snowfall, we are totally dependent upon the amount of precipitation in any given year to maintain the lake level. Keith Schaefer has written an informative presentation on the how and why of maintaining our lake level.

• Swimming Safety – Samples are taken from 15 sampling locations around the lake and tested for coliform bacteria levels. If readings exceed state limits the testing is repeated, and if necessary, the Health Department is contacted.

• Invasive Weed Control – The CLCS seeks to reduce the number of non-native weeds in high use areas, and sustain native weeds to promote recreational fishing and a healthy lake. Weed surveys are conducted before and during the peak season, and a treatment is applied in May if necessary.

• Lake Clarity – Lake clarity is tested throughout the summer season. If lake clarity standards are not met, a copper sulfate treatment may be applied in late June and/or early August. The goal is to maintain or exceed water clarity of five feet. Measurements are taken frequently and will be posted on the CLCS bulletin board at the Rt 7 corner of the lake during the summer months.

• Lake Chemistry – Phosphorus levels are monitored to assure that nutrients are not encouraging weed growth. High phosphorus levels can be reduced by encouraging people within the watershed to keep nutrients, especially lawn fertilizers with phosphorus, from flowing into the lake.
