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 4/16/19

Snake Below American Falls Reservoir: Flows out of the dam are on the rise. The CFS at this point is 17,200 and the reservoir is at 95%. Even with the flows coming up the water clarity is great and the fishing is still great. The temps have been a little warmer  and we are some some serious midge activity. The balanced leeches, worms, and smaller nymphs are also still producing well. Still plenty of time great fishing opportunities to be had. Wade access is becoming more difficult with the flow coming up, but the edges at most all of the access points have great fishing opportunities.We are also starting to see some small mouth activity, and with the weather getting warmer everyday its just going to get better.


Still Water/Lakes:  American Falls reservoir, Edson Fitcher, the wellness center, Hawkins, and most of our southern lakes are all ice free and fishing really well. The other lakes are still pretty well iced over, but would expect them to be fishing by the end of April into May. Midges and leeches are the name of the game. Full sink lines stripped slow along with indicator setups set just off the bottom.


Portneuf: The upper sections should have some great midge action going on. size 14-18 red zebras are a favorite of ours this time of year. Find the springs and you should find the fish, or any of the deeper slow moving holes. The lower sections through inkom should have the same results with more brown trout action. Starting to see some effects from run off, expect to see muddy high water through most of the lower river.


Snake By Tilden: Fishing has slowed in the upper sections above the reservoir. Still some great opportunities where the warmer springs are popping up. swing streamers in whites and blacks through the main section along with smaller midges, scuds, and frenchies under and indicator. Expect this to start fishing well by mid to late summer into the fall months.


South Fork: Flows are at 16,820 CFS with the reservoir at 66% full. Focus on fishing foam lines and fish in pools. Midges and smaller nymphs for your indicator rigs. Flows are pretty low for this time of year so use caution while on the water. Smaller streamers on floating lines in tan, white, and olive should produce some nice fish. Water clarity is still great, but would expect to start seeing high off colored water soon.

Henry’s Fork: Fishing is great on the lower sections of the hank right now. CFS out of IP reservoir is at 672. Water clarity is great and the fish are happy. Starting to see some great dry fly action the last week. BWO’s and some soft hackle swinging should treat ya well. If all else fails strap a rubber leg on there.
