The flush is on with flows out of Palisades Dam up to 18000 cfs. Flow at Heise is about the same. So it may be best to try elsewhere this weekend! As the flows lower to around 12000-14-000 cfs, likely next week, the South Fork will be back to what we all like this time of year.
Flows have been increased to 14500crfs. I talked to the Bureau of Reclamation today and they have decided to do the flush this weekend while they are making room in Palisades Reservoir for flood control. It is expected that flows will drop to normal summer time irrigation flows by Wed. next week. Although this is the plan things can change depending on weather and precipitation. We will keep you updated as things change with the flow situation.
We also have an update on the boat ramps for the South Fork. The BLM will be closing Conant and Byington Boat Ramps for the week of May 24-28. No vehicles will be allowed to enter the parking area and ramps will be closed. If you have questions on the boat ramp closures please contact Monica Zimmerman 208-524-7543
I just got the water report form the Bureau of Reclamation today and it has some information that needs to be passed to you our customers in regards to flows on the South Fork
Here are the key points from the Letter.
So if you are planning on fishing tomorrow the river is going to be blown out! If you are planning on fishing this weekend you will have plenty of water to fish and all of the boat ramps will be accessible except Cottonwood because the road is closed. If the flows do not increase after tonight the fishing should be back to normal in a few days. Nymphing rubberlegs and bead head nymphs will be your best bet. Streamers should fish fairly good on the lower river where the water is warmer.
Stay tuned to the fishing report and we will keep you updated on the flows of the river. We are expecting the flush next weekend but we don’t know for sure. It very well might happen on Memorial Day weekend like it has in the past. For any up to the minute advice, suggestions call the shop or email us.
By the way we got about 140% above average precipitation in April this year which has been really good to make up for the lack of snowfall this past winter. And the cold weather has held run off water int he mountains and slowed irrigation demands. What does this mean to us as fisherman? In August we should have cold water and more water in the system,which translates to healthier fish and more insect hatches! So the next time you wake up in the morning cursing the crappy cold weather, just remind yourself it’s helping the PMD hatches in the heat of August!
Flows on the South Fork have continued to increase due to irrigation demand from Farmers. This hasn’t been effecting the fishing to much because we haven’t seen major run off water yet and the weather has been cold. So the increases have been small and it hasn’t blown out the river. Currently the river is flowing at 4700cfs, it was raised yesterday morning.
We have some updated news on the Freshet Flush that we typically see every spring when we have the water. They are going to do the flush the 3rd week in May, it will be a flush that will have increasing flows for the entire week. We have been told that if the weather stays cool the flush will be in the upper teens. I would expect around 18,000cfs at the peak. If the weather warms up and the run off come quickly expect the flows on the flush to increase over 20,000cfs. After the flush the flows will drop down to normal irrigation flows which is about 12,000 to 14,000cfs. This flush is really important for the Cutthroats because it triggers them to head up to the tributaries to spawn, also it is good for the Cottonwood trees. All of the water that is flushed will be caught in American Falls Reservoir and none of it will go to waste.
People have been finding success fishing nymphs under an indicator. No word of Caddis on the surface but I have heard of some Skwalla’s flying around the river this last week. Streamers have also been fishing well on the lower river. We just got refilled on Rubberlegs and we got a bunch of new bead head nymphs. The rubberlegs are out and ready to purchase and we should have the beadhead nymphs ready by tomorrow at the latest.
Flows on the South Fork have been raised to 3500cfs. The water is off color but don’t let that keep you from fishing. The nymphing on the river is really good, and those rainbows are stacking up on the redds and eating egg patterns. With the chance to get a “money rainbow” fishing the redds is going to increase your chances of finding one. Streamer fishing is still kinda slow on the river right now and now major dry fly hatches to speak of. Call us at the shop for any other questions.
We screwed up and the road to Cottonwood is not open. It will not open until the Palisades Ranger District, which actually manages the road to Cottonwood, officially opens it for summer travel. This date varies from year to year depending on snow, weather and road condition. When the road does open the Palisades District will announce it through the media and their web site. If you have any questions you can contact them at 523-1412.
We apologize for publishing incorrect information and now have a thorough understanding of how the road is managed and by whom. When the road does open we will post it on the fishing report.
Flows are at 2100 cfs. This is not really effecting the fishing on the river right now. The water temp is still around 38 degrees which is keeping the trout from getting very active. There is runoff water coming into the system from Rainy Creek and Fall Creek and the other tributaries. The water clarity is off color but the fish are still eating. Blue Wing Olives are hatching on the lower river and fish are up on them. Nymphing is still the best option for hooking fish on the upper South Fork. For up to the minute reports call us at the shop.

We have much news for the South Fork. First, the USBLM opened the road to Cottonwood and Burns Creek on April 15th. All boat launch sites are open. Flow out of Palisades Dam is up to 1450 cfs (2060 cfs at Heise) making float fishing safer, but walk-in wade fishing remains a great alternative. As water moves down the river at these still low flows ( no significant runoff yet) it warms considerably. The result is that BWOs are emerging on the lower river, so add their life cycle patterns to your fly box when targeting that part of the river, particularly in the afternoon. Use the info Tim posted in the 4-14-10 South Fork fishing report for best success chances. Keep those streamers and rubber legs in that fly box, too. For the upper river and its colder water (canyon and upstream to the dam), those rubberlegs and streamers should be in your fly box, and add red or white zebra midges in smaller sizes.
We have received a solid conformation that Blue Wing Olives have been hatching on the South Fork from Wolf Boat ramp down to Menan. Lorenzo to Menan has had fairly high numbers of BWO’s hatching. Look for them in the foam, and the back eddy’s. Fish a size 18-20 and I would suggest fishing it behind a size 16 Parachute Adams.
We have had some customers asking about flows. Typically during this time of year we see and major change in the South Fork flows out of the dam. I talked to the Bureau of Reclamation this morning and was informed that flows on the South Fork will increase as soon as they decide to turn on the Great Feeder Canal. Due to the cold wet spring we have been having runoff is very slow and most of the moisture is remaining in the mountains. Everyone (anglers and farmers) is hoping for a delayed irrigation season due to the lack of snow we received. I was also informed me to expect flows around 2000 to 4000 cfs by the end of April. So all of this moisture and snow and cruddy weather that we have been receiving that is kinda getting annoying is actually really good for us as far as delaying the irrigation demand and keeping water in our system. This will translate to better dry fly fishing in August.
When flows increase on the river fishing will be put off for a day or two but will resume as soon as things get a little settled out. Fishing on the Upper section of the South Fork will be your best option if you are fishing on a day they increase the flows. When the water increases no dry flies will be hatching. nymphing and some streamer fishing will be the name of the game. We will keep you posted as things change.
