Southeast Idaho Fishing Report

In-Depth Fishing Report for The Snake River, Henry's Fork, South Fork of the Snake, Portneuf River as well as surrounding lakes and still waters of Southeast Idaho

Date 10/10/2020

Snake Below American Falls Reservoir:

The flows coming out are sitting at 2750 CFS and the reservoir is at 23% full. Water clarity is a touch off but getting better every day.The cooler over night temps have jumped started some fish to start putting on the feed bag. Sink tip lines and streamers in olive,white, and black have been productive for trout and bass. Deep nymph rigs with balanced leeches and caddis have been good as well. 

South Fork Snake River :

The flows are around 6699 CFS with the reservoir at 56% full.  The water is in great shape. Anglers have been having success on hoppers and other terrestrials throughout the day along with nymph rigs set up with small bead heads. 

Henry's Fork:  

Island park reservoir turned over a few days ago and the water on the upper stretches is off color. The lower river through Ashton is your best bet for water clarity and finding the best bite.  Hoppers and small attractor dries have been working well along with frenchies,caddis, and rainbow warriors in 14 & 16s. 

Lakes/Stillwaters: With the temps dropping we should see the weeds dying off over the next couple weeks. Most all of our reservoirs will start to fish really well in the coming weeks. Make sure your box is full of zebra midges, scuds, and your favorite leech patterns. 

Portneuf: Fishing has been pretty good above lava. Still some fish willing to look up at some hopper patterns along with tricos. Scuds and mayfly nymphs for your droppers have been best. Rusty brown and olive buggers have been sticking a few as well.
