The Lake has a total area of 2,260 acres (910 ha) and a maximum depth of 118 feet (36 m).

The lake is closed to most recreational activity, including ice fishing and swimming.

[3] In 2013, the Lake experienced several small algal blooms, though the fishing conditions and local water supply were not extensively harmed by the change in conditions.

Some of Maine's most sought after fish species are found in the lake, including Salmon, Lake Trout, and Brook Trout.

In recent years, Lake Auburn has also seen rising populations of warm water fish species such as Largemouth Bass and Chain Pickerel, which are now thriving in soft, shallow areas of the lake.
