Fishing and Boating

A 7.5 mile trail circles the St. Mary's Lake, allowing the area to be fished from shore or by boat (electric motor only). ​Fishing is prohibited on or behind the dam. Several species of fish are common to the lake including largemouth bass, chain pickerel, crappie, bluegill and sunfish. A valid freshwater fishing license is required for those 16 years of age and older.​ The lake has been designated a trophy bass lake and as such, special fishing regulations are​ in effect. Fishermen should check bulletin boards or contact park personnel for details. Electric motors only are allowed on the lake. A boat ramp is located on the lake.
