Hauser Reservoir
Special Notices & Closures
Fishing Report for the week of 09/28/2026
Good numbers of rainbows have been cruising the shorelines near the Causeway, and some nice fish are being caught from shore with a bobber and a crawler or leech pattern flies. Boat anglers are doing well fly fishing near Spokane Creek with streamers or leech flies. Walleye action has been good recently inside the Causeway Arm, near Dana Point, and across from Black Sandy. Most walleye anglers are doing best while using perch-colored jigs tipped crawlers or slip bobbers and leeches.

| 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. |
