Isabella Lake has a year-round open season but a large population of northern pikeminnow and overwintering cormorants have led to the cessation of rainbow trout stocking. However, a native wild cutthroat population provides some trout fishing opportunity. Largemouth bass, yellow perch and brown bullhead catfish are also present.
A state access with two toilets is available. The boat launch is suitable for smaller boats and canoes.
