Here are details about the upcoming flush out of Palisades Dam. Beginning Monday, May 11th, flow out of the dam goes up gradually to 19000 cfs by Friday, May 15th. Three days later flow will begin ramping down to 13000 cfs. So expect cold, fast water in the South Fork for several days beginning Monday. This is an effort to flush out developing rainbow trout eggs and fry to the benefit of native cutthroat that historically spawn later. Thinking of giving the South Fork a try with streamer and rubberleg patterns? Best do so this weekend!
Flow out of Palisades Dam is now just over 12000 cfs but rate of increase has really slowed last several days. Reason for increasing flow is irrigation demands in Magic Valley where growing season is way ahead for the time of year. Nymphing riffles is productive as water temperature is in low 40s, degrees F. throughout. Rainbows are spawning.
Flow out of Palisades Dam was increased each of the last three days making the South Fork water graph look like a step function. Now at 6530 cfs out of the dam, flow at Heise is a bit higher, and water temperature there is now in the low 40s in degrees Fahrenheit.
With the recent cold weather snap we are having, the open water fishing on Henry’s Lake is probably done for the year. The lake will most likely be frozen over within a week or so if these conditions continue. If by some chance the weather warms up and the lake stays open, look for fish to be extremely scattered and suspended in deeper water. However, if you are into ice fishing, you have until January 1st to enjoy the great ice fishing opportunity Henry’s presents.
Stillwaters to the South should continue to fish okay, but this extreme cold weather is really going to slow things down. Be sure to cover a lot of water when fishing this time of year! Springfield reservoir is one exception here, fishing seems to be excellent down there as long as you can stand the cold. Fishing small chironomid pupa (size 14-20) under an indicator typically produces best. Springfield was stocked recently so there should be plenty of 17″+ fish down there willing to take a fly.
Conditions are constantly changing this time of year, so be sure to give us a call or stop in for up to the minute information!
Flow out of Palisades Dam was reduced to 938 cfs from around 2400 cfs on November 4th. Flow at Heise is now 1290 cfs. This is great for wading, but makes boating a bit tougher. Fish will be concentrated. So it is time to get out and pitch your favorite streamer pattern or enjoy the BWO’s emerging and trout responding, especially in some of the predicted upcoming stormy weather.
The new Lorenzo boat ramp is now open! This will be a big improvement over the old ramp and will provide use for years to come. The old ramp is now demolished an unusable. The new ramp is located about 1/2 mile downstream from the old one on river left (opposite side from old ramp). Access to the new ramp is off the Menan/Roberts exit off Highway 20.
Henry’s Lake has been fishing well this past week. Things seem to have finally turned around up there. Fish have been caught on the west shore from Duck Creek to Staley Springs, The Northshore, the Cliffs, and State Park area. Water from 2-8ft deep has been most productive, fish that with an intermediate or type II line and hang on. Fly patterns that have been producing are black crystal buggers, midnight fire, and Lt. Olive and Tan crystals. Get up there while you can, any time you are able to fish on Henry’s after the end of October is on borrowed time. Only a matter of time before the lake will be frozen solid.
Other Stillwaters in the area have been fishing well lately too. Daniels and Springfield have been the most consistent fishing. Chironomids (any color size 10-18) under indicators and leech patterns mentioned above in the Henry’s lake portion have been the best patterns. Fishing in the late morning/afternoon has produced better then being out there at first light. Chesterfield is the one lake in the area we have not heard anything good lately. We have received a lot of calls regarding this very popular lake and the news just isn’t good. I believe two consecutive years of extreme drawdown and summer heat have had an impact. There are still some very nice, maybe the nicest in the area, fish to be had, but they are few and far between. If you do decide to head up there, fish hard and cover a lot of water! Hebgen, Hawkins, and Island Park have all been fishing good lately too, toughest decision this time of year is just deciding where to fish!
Please give us a call or stop in if you have any questions on the local stillwater scene!
We have recently been fly fishing the Blackfoot River about ten miles below the dam. Water flow is less than normal meaning fish are concentrated in deeper runs and holes. Streamers and small wooly bugger types worked for us in these waters. We noticed that hoppers were still around, so a variety of hopper patterns worked. Some BWOs came out in shaded areas such as in the shadows of cliff faces, and fish responded. Roads were in great shape.
Henry’s Lake has been fishing okay lately, right on the cusp of really turning loose. We need some colder, nastier, cloudier weather to really get things going, weather has just been too nice! Focus on all the typical fall areas; Duck Creek, Hatchery, State Park, Cliffs, Duck Creek, and County boat dock. Until the colder weather shows up, fish a little deeper water then you typically would this time of year. Darker Leeches, Lt. Olive Crystal, Henrys Lake Renegade, and Henrys Lake Scud have all been producing well. Look for things to really turn on here in the next week or so!
