Bone Lake

At 221 acres in size, Bone Lake is the third largest lake in the District and is considered an "active recreation lake." An area of 5,586 acres (including Moody Lake and Third Lake) drains to Bone Lake which then outlets to an unnamed stream that flows northwest to Birch, School, and Little Comfort Lakes. Although considered a deep lake, Bone exhibits some shallow lake characteristics because 58% of its area is in the littoral zone where rooted plants can grow. Bone Lake has a public boat landing and is used recreationally for swimming, fishing, and motorized and non-motorized boating. In 2004, it was placed on the State's Impaired Waters List due to high nutrients. It generally receives a lake grade of "C" with monitoring data from the 1980s through 2011 suggesting that the water quality of the lake has been fairly consistent.
