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
Snake Below American Falls Reservoir: Flows out of the dam are 13,000 and the reservoir is at 68%. The reservoir is dropping at about 1% a day and the out flow has been consist for the last week and will likely stay that way for a while. Water temps are rising and the bass have moved towards the edges. Still throwing the same sink tip set ups with krinklezon clousers and other flashy bugs. Deep ntmph rigs with balanced leeches and rubber legs have also been producing bass and some trout. With the water temps up the top water bite has been getting good so don’t hesitate to throw some big hoppers and mice.
South Fork Snake River : Fork Flows are at 12,591 CFS with the reservoir at 96% full. Water clarity and flow is perfect right now! Anglers are working riffles with nymphs (e.g., zebras and prince nymphs) and bullwhip worms with really good success. larger white Streamers have also been moving fish. Salmon flies have made their way to the upper and the big bug action is awesome. Look for drakes, PMDs, yellow sallies, and few goldens as well.
Henry’s Fork: PMDs and flavs have been the bug of choice for the dry fly action the last couple weeks. Rubber legs, frenchies, and your favorite caddis nymph have been the ticket for the subsurface bite. Henry’s lake is still fishing really well with brown leeches. Smaller streamers should be seeing some great hopper fishing in the next couple weeks as well.
Still Water/Lakes: The damsels have popped and the fishing is starting to slow with the higher temps and weed growth. Chesterfield is still full and fishing the deep water with leeches and midges has been productive for bigger fish. Fishing will become tougher as the summer goes on but this fall is going to be GOOD!
Portneuf: The upper river is in great shape and the fish are happy. Tons of PMD action in the evenings. Sow bugs and scuds with pink or orange in them have been solid dropper and nymph rig options and smaller brown and olive streamers have been getting some eats. Wont be long and the hopper fishing will be off the charts.
Blackfoot river: Smaller dries have been the name of the game over the last week. PMDs, caddis, and small sallies have been getting munched. Don’t hesitate to have some big yellow foam bugs as. Just like the portneuf we should be seeing the bigger hoppers any week now. Fish the deeper holes with mid ranges streamers and soft hackles for the best results.
