Blue Lake is 16 hectares (40 acres) in area and 28 metres (92 ft) deep.
 Its surface is entirely open water, with boulders reaching the shore in the east and north east, and the other shores being pebbly.
It lies about 28 kilometres (17 mi) west of Jindabyne and 3.5 kilometres (2.2 mi) north of Charlotte Pass at an altitude of 1,890 metres (6,200 ft) above mean sea level, in a glacial landscape.

The lake was formed when glaciers flowing from the Great Dividing Range converged and carved out a basin in the granite bedrock.
It receives water from Blue Lake Creek, originating from Mount Twynam and from snowmelt.
The surface of the lake is frozen for about four months of the year; it overflows in spring with the melting of the snow while, during the rest of the year, the water level remains stable.
