South Fork 5-20-17

Flow out of Palisades Dam has been reduced sequentially over the last several days. Currently it is 10400 cfs, and 11100 cfs at Heise. Palisades Reservoir is about 29% full but rising because the upcoming irrigation season will soon be demanding water. This demand will counter run-off coming in, so BuRec is doing a “balancing act”  by catching in-flow, lowering flood potential, and storing water necessary for irrigation.  With lower flows below Palisades Dam, look for the river, although somewhat discolored, to be safer, more easily approached, and fish easier to encounter.  Because waters remain cold, nymphing and presenting streamers will be the most effective means for hook-ups. Bead head nymphs, rubber legs, San Juan Worms, and streamer patterns of choice should be effective when fished through riffles and into runs, slower water, and below islands.

Whether it is Box Canyon, Cardiac Canyon, or the lower river, you can bet that large stonefly nymphs are on the move towards shallow water. That means the whole array of large nymph patterns available from rubber legs to fancier renditions will be effective in waters such as these. Flow out of Island Park Dam is just under 1000 cfs and appears likely to remain at that level for the time being, so look for a stable river at least down to the Warm River-Robinson Creek and Fall River confluences for now. In addition to stonefly nymphs being effective, March brown and caddis  life cycle patterns bring responses on the lower river, and bead head nymphs of choice bring action there and in Box Canyon waters.  During our recent cold spell flow into the river coming from Fall River has decreased. However look for Fall River to put a lot more water into the river during the upcoming predicted warm weather.

Yellowstone Park 5-20-17

Yellowstone Park fishing licenses are in the shop.  These include:

Season permit ($40)

7-day permit ($25)

3-day permit ($18)

Non-Fee permit (Fifteen years or younger)

We also have 2017 Park fishing regulations, and they are on the Yellowstone Park Official Web Site under “THINGS TO DO.” Consider looking them over.

The Park fishing season opens on Saturday, May 27th. Most streams will be high with run-off opening day weekend and longer. The Firehole River will be the best place to fish. Look for BWO life cycle, white miller, small bead head and traditional nymphs of choice, and various caddis life cycle patterns to be the most effective there. Also expect plenty of accompanying fly-fishers.  Nez Perce Creek may also be fishable, but certainly less crowded.

South Fork 5-6-17

Flow out of Palisades Dam was raised to 17600 cfs yesterday (19800 cfs at Heise). This makes wading more perilous, but the length of high flows should result in an effective flush for sustaining cutthroat trout in the river.

Still Waters 5-6-17

In mid April IDF&G released 1800 tiger trout in Jim Moore Pond (aka Roberts Gravel Pond). In mid May another 3600 are scheduled for release.  Presenting small streamer and leech patterns is likely the best way to encounter these unusual trout in this safe and easily approached water body.

Yellowstone National Park management is evaluating prohibition of items having high potential to transport invasive species. Among these items is felt soles commonly used as secure footing on waders and boots. It is possible that felt soles could be prohibited for use in park waters  in a few years.

All types of park fishing licenses will be available in Jimmy’s for the Memorial Day park fishing season opening

Stillwater goes as the weather goes

Stillwater fishing has been very tough on area reservoirs since ice out. The cold weather has been keeping water temperatures way down and bug activity to a minimum. Of all the lakes Springfield has been fishing best, although even that hasn’t been very good. If you go to springfield, small chironomids and leeches have been best. We really need water temperatures to get and stay above 50 degrees before things really get going. Once that happens, look for chironomids to start popping on all area reservoirs and fishing to drastically improve.

South Fork 4-25-17

Flow out of Palisades Dam currently is 14600 cfs (15700 cfs at Heise). Wading remains a bit perilous, and boating gets you to the best waters. Presenting rubber leg and streamer patterns remain the best ways to encounter trout. Smaller nymphs presented in or at the base of riffles will get action from trout as well as from whitefish.

Action at Springfield Reservoir is improving. Just find the taking depth for a midge pupa pattern under an indicator, and action will come. Small leech or damselfly nymph patterns also produce.

The lower Warm River to Ashton reach featured a blanket caddis hatch last weekend. So fish seemed filled with these. From Warm River downstream to Chester the river is a bit high but clarity is about normal. The same applies from Ashton Dam to Chester. Streamers and big stonefly nymphs are the best patterns to try both places for larger fish. Midges abound, but BWOs seem spotty (good numbers some places, not so good others).  Midges are dominant at Last Chance were your choice of bead head nymphs in sizes around 12-14 work best.
