Lakeside homeowners, dock and marina users, and anyone within the watershed (the area from which water flows into the lake) all impact the quality of Copake Lake.
YOU can help to protect Copake Lake by preserving or mimicking natural processes in the watershed, so that water flowing into the lake stays as clean as possible.
ARE YOU LOOKING FOR LAKE MAPS? WANT TO LEARN MORE ABOUT WILDLIFE AROUND THE LAKE? INTERESTED IN LONG-TERM TRENDS LIKE WATER CLARITY? Then this section is for you. We have compiled many resources for our members.
Due to current budgetary constraints the Copake Lake Conservation Society Grants Program will be suspended until further notice.
The temperature in the lake is in the 60s in early spring, typically warms up to early 70s by Memorial Day, and peak lake surface water temperature is typically reached in early August. Peak summer temperature measured in the center (the shallows will be warmer) is commonly about 82 degrees Fahrenheit. The actual water temperature varies naturally with depth and season. It is the major factor controlling when the ice forms and breaks up during any winter season.
The filamentous algae in your area is a naturally occurring result of clear water and abundant sunlight. The algae grows on the bottom and as it produces oxygen can rise to the surface and form mats. It is a green algae and is not hazardous to health. Our recommendation to shoreline owners is to take action on their own and rake or skim the algae from their areas and dispose of on land. It is harmless, it just looks icky.
