The drainage area of the lake is 81,056 acres including three major tributaries: East Branch of Sebasticook River, Mulligan Stream, and Stetson Stream. The total drainage area encompasses portions of Penobscot County, and to a much lesser extent, Somerset County.

The lake provides for many recreational activities: swimming, boating, fishing, and snowmobiling, for tourism and for residential development. Both the lake and its shores provide habitats for several wildlife species, such as sea run elwives, smelts, smallmouth bass, white perch, black crappie, and many bird species. Sebasticook Lake is easily accessible to many Mainers. Within a ten mile radius of the lake resides approximately 17,730 people.
