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 5/27/20

Snake Below American Falls Reservoir:

The flows coming out are sitting at 13200 CFS and the reservoir is at 100% full. Water clarity is still a touch off but not bad. The bass bite has been picking up everyday and the warm weather will help. Still finding a few trout in the deep slots as well. Fishing streamers on sink tips have been the most effective.

South Fork Snake River :

The flows are around 11894 CFS with the reservoir at 73% full. The water looks amazing and the fishing is even better. The overcast days have made for great BWO action. Nymphing rubblerlegs and your favorite mayfly patterns have been getting good as well. Gold and white streamers in various sizes have been producing some nice fish.

Henry's Fork: 

The Salmon Fly hatch is still rolling up on the hank and should see it throw the week. BWO and caddis have been solid on top as well. Rubber legs and smaller mayfly nymphs will get the job done under a bobber.


The lakes are still fishing really well. The water temps are still cold and the fish are happy. Tons of great midge and scud action to be had on all the southern reservoirs. Damsels should be right around the corner as well.


The upper portions are still running a touch high and water is off color. Flashy streamers have been an effective method for picking up a few. Once the water clears the PMDs should be rockin.
