Holter Reservoir
Special Notices & Closures
Fishing Report for the week of 10/13/2026
Most boat anglers stayed off the water this weekend due to the cold weather. Trout fishing has been great from shore at the Gates of the Mountains, the BLM campground near the Dam, and Departure Point while using nightcrawlers and a marshmallow, powerbait, or leech pattern flies. Look for a good walleye and perch bite to continue inside the Canyon, Cottonwood Creek, and near the Clay Banks while jigging in 25 to 40 feet of water.
