Holter Reservoir
Special Notices & Closures
Fishing Report for the week of 06/22/2026
Good numbers of rainbow trout are still being caught while using small nymphs near the Gates of the Mountains. Boat anglers searching for trout have been doing best while trolling flashers and spinner combos from Log Gulch to Split Rock. Some nice walleye and a few perch are being caught in some of the small weedy bays inside the Canyon, near Cottonwood Creek, and around the Clay Banks while pitching jigs and crawlers, trolling bottom bouncers and worm harnesses, or using slip bobbers and leeches. A few perch are being caught throughout the reservoir while searching for walleye. A few kokanee salmon are being found while trolling various flashers with wedding rings or Hoochies between the Dam and Juniper Bay. Most kokanee are being found around 50 feet deep. A few large northern pike are being caught while casting spinners or spoons around weed beds.
