South Fork of the Snake River Fishing Report

Given the time of year, the fishing on the upper section of the South Fork of the Snake River is solid right now. Gone are the 50+ fish days of summer in which it seems that every fish is dying to eat a stonefly or PMD. Alternatively, water temperatures are down and trout are moving into their winter holding water. Long deep runs, deep soft seems, and deeper tailouts are the best places to find fish, although deep banks with structure are holding the occasional trout as well. Fast and shallow riffles are pretty much void of fish, so don’t waste your time. Although you can still cover more water by floating, the wade access is plentiful right now and will be throughout the winter. The flows at Irwin and Heise are at 910 and 1400 cfs, respectively.

Some browns are still spawning and there are a lot of clearly exposed redds out there. Instead of targeting the vulnerable fish that are in the act of spawning, target deep runs that are nearby as there’s a good chance there are a couple of trout holding there. Although it should go without saying, be sure not to walk on the redds. 

The match the midge-hatch dry fly fishing can be good to great right now. Although there are quite a few white fish rising from late morning through the middle of the day, there are also a lot of pods of rising trout eating midge adults and midge pupa. It seems like the rising trout tend to be in a little deeper water. The fish rising in 8 – 18 inches of water are usually (but not always) whities. To hook up with these trout, throw a sz 20 – 24 Griffith’s Gnat with a midge larva or pupa pattern off the back. That should do it… Given the low and clear water, the trout can spook a bit right now, especially from the wake of a boat and/or oar. 

The nymphing has been okay. Medium to smaller-sized Pat’s Rubber Legs have been producing a few trout each day, especially during the middle of the day. Egg patterns and midge larvae will also produce some hookups, although many of these hook-ups will be with white fish. 

Finally, the streamer fishing has been hit or miss. On the “hit” days, it’s been quite good in deep pools and runs. Don’t be afraid to fish the middle of the river sometimes. Unlike the days when the river is at 10,000+ cfs, at low flows some nice trout can be in this water.
