Eastern Idaho Fly Fishing Report – December 2018

South Fork of the Snake River Flows: ~ 900 CFS at Irwin,  ~1300 CFS at Heise Winter has settled in, but with the current Winter flows on the South Fork of the Snake River it has opened up the river to really accessible wading opportunities. Remember to look for your Winter holding spots for trout and not the places you would fish in the summer. Long flats after large bends are some of the best winter fishing spots to key in on.  Nymphing has been the most productive application. You will see midges coming off during the temperature variances of the day, especially if its overcast/cloudy.  Nymphing small rubber legs, zebra midges, small tactical nymphs, and egg patterns will be the most productive patterns.  Remember that getting down to where the fish are holding is paramount so you may need to use a more substantial point fly or split shot in combination with your small nymphs.  If you enjoy streamer fishing, make sure to use a slow retrieve in Winter instead of a more active strip that you would use during spring, summer, and fall.   Henry’s Fork of the Snake River  Upper River:  Box Canyon ~ 480 CFS Box has been fishing well, and access will continue

Introducing the South Fork Initiative

Many of us, on our adventures in Henry’s Fork country, have also traveled south to explore the South Fork of the Snake River (SFSR). However, during your travels you might not have realized how interconnected flows and management of the Henry’s Fork was to SFSR The SFSR from Palisades Dam to the Henry’s Fork confluence is roughly 60 miles long, supports robust populations of Yellowstone Cutthroat Trout, Rainbow Trout, and Brown Trout, and flows through cottonwood stands, canyons, and a braided flood plain. Management of the SFSR system, especially in regards to water management, can directly affect streamflow in the Henry’s Fork. So, when a group of SFSR outfitters and concerned citizens approached HFF and asked us to expand our brand of research and collaboration to the SFSR, we took note. They expressed concerns about how fluctuations in SFSR flows might be affecting macroinvertebrates and fish populations, about summer water temperatures and fish habitat, and if restoration projects could boost trout populations and the fishing experience, while still meeting irrigation demand. If we look back five, ten, or twenty years, these same questions were being asked about the Henry’s Fork. In fact, understanding the answers to these questions were a

Eastern Idaho Fly Fishing Report – October 2018

Late fall is in full swing here in Eastern Idaho.  The weather has changed & the Indian summers have given way for October fishing. The key to having a great day is to dress in layers and bring your baetis box. We’re targeting little fall bugs on the  Henry’s Fork,  South Fork of the Snake, and  Teton River. Baetis & October caddis are both being targeted on all three rivers.  If you’re fishing the South Fork of the Snake River we’re also using the occasional grasshopper using the hopper/dropper technique. Subsurface is also highly productive using Zebra Midges #14-18 (black, red, & chocolate), and little pheasant tails (#18-20) for nymphing.  We’ve been having the most success with black & olive colored streamers. Have fun & fish on!

The great spring 2018 sediment flush continues to impact water quality and the fishing experience

Main message: The great spring sediment flush we observed earlier this year not only impacted fishing during Memorial Day weekend—by contributing to high flows and turbidity—but has continued to impact the fishing experience from Box Canyon through Riverside this season in two plainly obvious ways: depressed hatches and higher than average amounts of uprooted floating plant material. In addition, the rainy and cloudy weather that contributed to the spring flush may also have contributed to later hatch timing of some species earlier this summer. Recall my blog from June 8 where we quantified the amount of sediment that was flushed out of each reach of the Henry’s Fork, from Island Park Dam to Ashton Dam, during the major runoff events we experienced during April and May. These spring rains brought the highest spring runoff flows in 7 years to the upper Henry’s Fork watershed! Our network of water quality monitors showed that these flows were strong enough to provide a major springtime sediment flush—a natural rhythm of our local hydrology that provides significant benefit to trout and aquatic insect habitat. We’ve seen much higher summertime flows than these in the last 7 years, but what was significant about this spring’s

Blog in response to Island Park flow transfer on July 15, 2018

Prepared by Melissa Muradian and Jack McLaren What happened? Due to warm water temperatures and low dissolved oxygen in the water at the intake to the Island Park hydroelectric plant, the plant’s aerators have been unable to maintain dissolved oxygen in power plant outflow above the level required by their operating license. Thus, the plant shut down yesterday morning (July 15), and all outflow from Island Park Reservoir was shifted to the bottom-withdrawal gates on the west side of the dam.   How does this affect the river’s water quality? Temperature: Water delivered through the dam gates is from the bottom of the reservoir and as long as thermal stratification remains in the reservoir, the gates will deliver cooler water than the power plant. However, the response we saw in temperature was about 1 ˚C (approx. 2 ˚F) at our IP East sonde. We saw no discernable difference in water temperature by the time that water made it to Pinehaven. Thus the cooler water temps that result from total flow coming out of the gates only last until some point upstream of Pinehaven, and most likely only last until part-way through Box Canyon. Dissolved Oxygen (DO): DO was hovering at
