Overview
Cass Lake is a natural lake in MN. It is managed by Minnesota DNR / Chippewa National Forest.
The basin is characterized by about 15,960 acres of surface area, a maximum depth near 120 feet. Shoreline and bottom character vary from protected coves and flats to deeper water, supporting a mix of open-water and nearshore habitats.
Cass Lake supports recreational boating and fishing. Public access is through area ramps, parks, and shoreline facilities where provided by the operator. Fishing and boating regulations are set by the relevant state wildlife agency.
Cass Lake is not operated to a classic reservoir full-pool curve. Where a gauge exists, water-surface elevation is the reference. Conditions still matter for boating, fishing access, and shoreline use.
