Hauser Lake is a 3,200-acre reservoir created by Hauser Dam on the Missouri River near Helena, Montana. The lake reaches depths of up to 70 feet and offers diverse paddling opportunities. Several campgrounds and recreation areas provide access, including White Sandy Campground, Devil's Elbow Recreation Site, and Black Sandy State Park. These sites offer boat launches, courtesy docks, and amenities like picnic tables and fire rings.

Paddlers can explore the lake's 28 miles of shoreline, taking in views of the Big Belt Mountains and Eldorado Bar. The Missouri River Walk, a 1.5-mile trail near the lake, provides opportunities for wildlife viewing. The lake supports populations of rainbow trout, brown trout, walleye, and perch, making it popular among anglers.

While open year-round, the best time to paddle Hauser Lake is late May to early June when temperatures are warm but crowds are smaller than peak summer months. Summers can get busy with motorized boats, water skiers, and jet skiers, so paddlers should exercise caution. The Lakeside Bar, Restaurant, and Marina offers a swimming area and small beach, though there is no lifeguard on duty.

Rental options for kayaks, canoes, and paddleboards are available through local outfitters. Rentals typically include life jackets and basic safety equipment. When planning a trip, be aware that use of watercraft is not permitted after dusk. Children 12 and under are required to wear life jackets at all times on the water.

Hauser Lake's proximity to Helena (about 7 miles or a 24-minute drive) makes it easily accessible for day trips while still offering a less crowded alternative to some of Montana's more well-known lakes.
