Grave Lake is a 157 acre lake located about 8 miles east of Brainerd in Crow Wing County. There is no public access on the lake. The lake is heavily developed with 65 homes/cabins along 2 miles of shoreline. The maximum depth is 13'. Shallow water substrates are primarily sand and gravel. The aquatic plant community is somewhat diverse with 20 species present. Emergent plants such as bulrush and water lilies are important for shoreline protection, maintaining water quality and provide essential spawning habitat for bass and panfish species. Submerged plants provide food and cover needed by fish and other aquatic species.
