​As a reference point, the lake is deemed full any time there is water flowing out of the lake through the spillway. In the early 1900s, the lake was able to remain full most days of nearly every summer. It now is not always full every day of every summer. The main reason for all this is that the watershed, our primary source of water, has gone from nearly all fields to nearly all forest. Anywhere from 40% to 60% of rain falling on fields runs off into the lake. Only about 20% runs off our now forested watershed. We simply don’t get as much water as we used to. This change has happened during the lifetime of many of our current residents. There is realistically no way to change this. We simply have to adapt to the current conditions.
