Lake Helena is a 2,072-acre reservoir located approximately 7 miles north of Helena, Montana in the Central Fishing District. Connected to Hauser Reservoir, this shallow, turbid waterbody is known for its excellent spring and fall walleye and perch fishing opportunities. The lake's shallow nature allows it to warm quickly in spring, drawing various fish species up from the Causeway Arm of Hauser Reservoir to spawn. Lake Helena offers diverse fishing experiences throughout the year, particularly for those targeting walleye, perch, and trout, making it a popular destination for both local and visiting anglers.

Montana Stream Access Laws

Under the Montana Stream Access Law, the public may use rivers and streams for recreational purposes up to the ordinary high water marks. Although the law gives recreationists the right to use rivers and streams for water-related recreation, it does not give them the right to enter private lands bordering those streams or to cross private lands to gain access to streams without landowner permission. Montana's stream access law ensures public access to surface waters by public bridge or county road right-of-way. The width of a public bridge or public road right-of-way easement is the same as the public highway to which it is attached.
