Hauser Reservoir
Special Notices & Closures
Fishing Report for the week of 04/20/2026
A few rainbow trout, walleye, and perch are being caught in Lake Helena, from the Causeway Bridge and inside the Causeway Arm when the wind conditions have allowed anglers to get out on the water. Trolling bottom bouncers and spinner rigs, Crankbaits, or cowbells has been working well, and shore anglers are having luck with nightcrawlers on a floating jig, Power Bait, Various spinners, or flies.

| Status of the Fishery: | Hauser Reservoir, including Lake Helena, is home to some unique fishing opportunities in the Helena Area. Annually, yellow perch, walleye, and rainbow trout, all spring spawners, draw anglers to the river below Canyon Ferry Dam and Lake Helena. In the river below Canyon Ferry Dam, shoreline anglers do well on the east shore near Riverside Campground (Bureau of Reclamation) and on the west shore, via Eagle Bay Drive, for both rainbow trout and walleye from approximately late March through June. Boat anglers have access below Canyon Ferry Dam via the boat ramp at Riverside Campground and have excellent opportunities for rainbow trout and walleye in the spring from the dam to Spokane Creek Bay. In Lake Helena, its shallow, turbid water allow it to warm quickly in the spring, which draws yellow perch and walleye up from the Causeway Arm of Hauser Reservoir to spawn. Peak spring angling opportunities occur from late March through late May or until increased vegetation growth prevents angling success. Shoreline anglers have success in the spring on Lake Helena at the Causeway Fishing Access Site (FAS) and boat access is limited to the Lake Helena FAS (FAS) boat ramp. Be aware that Lake Helena is very shallow (less than 10 feet deep) and a no-wake restriction is in place most of the year to protect waterfowl production. |
