[3] It is named for a small piece of land, Fisherman Island, located some 900 feet (270 m) from the mainland.

For most of the period from 1998 to 2016, historically low lake levels resulted in the island becoming attached to the mainland via a tombolo.

[4] The park's interior terrain consists largely of rolling dunes covered with maple, birch and aspen broken up by bogs of cedar and black spruce.

The park offers picnicking, swimming beaches, over three miles of hiking trails, hunting, and snowmobiling.
