​​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 through rain and snowfall, we are totally dependent upon the amount of precipitation in any given year to maintain the lake level.

 

In the fall and winter, the lake drain valve is opened in order to lower the lake level, thus minimizing shoreline erosion due to ice movement during the spring thaw. Depending on weather conditions, the drain valve is closed in the late winter or early spring to refill the lake. If the lake and/or the ground are not frozen, and/or there is no snow on the ground, typically the drain valve is closed in January. If there's a foot or so of snow on the ground and the lake is frozen, closing the valve can wait until mid- to late-February, or even later. It has been closed as early as January and as late as April. In both of those extreme cases, the lake has been full again before the start of summer. The Lake Management Committee, based on prior experience and careful monitoring of weather conditions, makes decisions regarding when to open and close the valve.
