School Lake

School Lake is a deep lake with a surface area of 49 acres and a total watershed area of 8,272 acres that includes 10 lakes. The main tributaries to School Lake are drainage from Birch Lake and the local northern portion of the watershed entering at the east side of School Lake. School Lake has no public boat access and is used for passive recreation like non-motorized boating, fishing, and wildlife viewing. It has poor water quality and it included on the State's Impaired Waters List for high nutrients. A 2008 survey identified a diverse plant population in the lake although curly leaf pondweed was present throughout the lake with the highest density along the northern shoreline.
