The Androscoggin flows into Merrymeeting Bay in the Kennebec River estuary.

The north end of the lake overflows into the Little Androscoggin River through the village of Oxford.

The lake forms the boundary between Otisfield to the west and Oxford and Poland to the northeast and southeast, respectively.

Greeley Brook is the largest tributary to the lake, and flows 7 miles (11 km) from Sand Pond in Norway.

[2] The lake is good habitat for smallmouth and largemouth bass and has been stocked with trout.
