Hydrology
The lake is the end of the western branch of the Brightsand River arriving from the direction of Seseganaga Lake and immediately from Sunray Lake; the inflow is at the southwest. The outlet channel at the north combines with the eastern branch of the Brightsand River arriving as the outlet from McEwan Lake to form the river Allan Water. The Allan Water flows via the Ogoki River and Albany River to James Bay.
There is one named island in the lake, Star Island. The line of an esker runs intermittently north-south through the east side of the lake, the continuation of an esker on land to the north of the lake.
