Ice Fishing

Ririe Reservoir
In January Ririe Reservoir typically freezes and provides opportunity for hard water anglers. For those willing to drive a bit farther Mackay Reservoir, Paul Reservoir, Island Park Reservoir, Palisades Reservoir and Ashton Dam all have quality fisheries that provide lots of winter fun!

It's important to remember to check ice conditions prior to venturing out. Ice can change from day to day as reservoir levels fluctuate. Don't take safety lightly when fishing through the ice!

South Fork/Henrys Fork Snake Rivers
The South Fork and the Henry's Fork from Ashton Dam downstream are open through the winter months. Anglers will want to keep an eye on the weather report and try their luck on warmer days during the warmest hours. On the South Fork, try rubber legs and bead-head nymphs and concentrate on the deep pools. The same strategy applies to the Henrys Fork but you might also add dry flies and midges to the mix.
