Fishing Reports

Henry’s Fork 10-10-15

Almost anywhere along the river below the Warm River confluence will be a good location for encountering migrating brown trout. One location with excellent potential and plenty of room is along the river above the Wendell Bridge ( Highway 20). This puts one in position to intercept browns moving out of Ashton Reservoir which produced the current state record brown a few years ago.  Early mornings and evenings will be best times, especially during these bright clear days. Oh, for some stormy weather!

South Fork 10-10-15

Again the discharge graph for flow out of Palisades Dam looks like a step function. It is down to 5250 cfs (5620 cfs at Heise) as of yesterday. With Palisades Reservoir down to 29% of capacity, more flow reduction is coming up to begin the storage season. Therefore look for more wading opportunities along the river. The bright weather forecast for the next several days will diminish the BWO and Mahogany dun activities, but presenting streamers during early and late times could bring larger fish to strike.  Also, we have heard of some success for folks casting rubber leg patterns on the downstream side of riffles.

Henry’s Fork 10-6-15

Flow out of Island Park Dam was increased yesterday from around 200 cfs to nearly 300 cfs. Doesn’t sound like much, but at such a low flow it impacts best locations for wading.  It is still a tough flow for drift boating, but remains good for wading.  Big rubber legs and streamer patterns are the way to go this time of year.  BWO activity is providing action almost everywhere on the river, upper and lower. Good streamer fishing on the lower river continues because browns are migrating.  Locations to try are numerous in the river above Ashton Reservoir to Warm River.  Others include from the Vernon Bridge upstream to Ashton Dam, below Chester Dam to St. Anthony, and in the river below St. Anthony (Sounds like the whole lower river!).

South Fork 10-6-15

Flow out of Palisades Dam was dropped to 6770 cfs early this AM.  That means more walk-in wade opportunities. Come in and talk to us about best locations to try. BWOs are going strongest during cloudy PMs and are accompanied by mahoganys. If you try the river during low light conditions such as those BWOs favor for emerging, consider that browns will begin moving big time as we cool off. That means streamer patterns should be in your fly box anywhere on the river.

Henry’s Lake 10-6-15

Fly-Fishing the north shore has definitely slowed (voice of experience) even though fish are in shallow water. Likely this is the same around the lake. One reason is warm water for the time of year. We measured water temperature at middle 50s in Deg. F. yesterday. For sure cooler water will improve fishing success.

Small Streams 10-1-15

It’s the time of year when certain small streams become difficult to fish with success. This is because (amongst other things) through dropping to base level water and cooling off, they lose overhead cover and foodforms become  less available. When better conditions are available, residents of these streams will move to more hospitable waters. Local examples include such as the Warm River drainage tribs including Robinson, Rock, and Wyoming Creeks, and some of the Teton Basin tribs to the river.  Other small streams maintain good living conditions for salmonids year round. Fall,Teton, and Warm Rivers are examples. So are such as Big Elk and Bitch Creeks.  There are a lot more small streams around here that you can enjoy until the roads close or the snow flies. Come in and talk to us. We can suggest candidates.

South Fork 10-1-15

Flow out Palisades Dam has been about stable for several days at around 7400 cfs. This is about 3000 cfs higher than normal for the present, but low enough to offer some wading. Flow will soon come down as Palisades Reservoir is just under 30% of capacity with storage season just around the corner.  With uncertain weather continuing, look for good BWO activity and trout responses and the same for mahogany duns. Although Henry’s Fork browns are on the move in the lower river, it is early for the same to be significant in the colder South Fork, but having streamer patterns in that fly box is a good idea.

Big Lost River 10-1-15

Flow out of Mackay Dam is at 200 cfs, an amount that makes wading practical. Flows out of the dam will likely go lower as storage takes over in the reservoir. Tricos are diminishing, but BWOs are coming on, and there always is plenty of midges for fish to key on.

Henry’s Fork 10-1-15

BWOs are bringing action from fish in the Last Chance-Harriman area and a few mahogany duns are around. Terrestrial insects and caddisflies are on the decline. Stonefly nymph patterns seem to work well in Box Canyon, especially during overcast and low light conditions. Browns are moving on the lower river meaning it is time to break out streamer patterns to be presented under low light conditions.Just above Ashton reservoir is a good place to try, but so are below Ashton Dam and Chester Dam. The uncertain weather predicted for the next several days also means good BWO activity, so don’t choose between their life cycle patterns and streamers. Take both!

Henry’s Lake 10-1-15

It looks like the lake is making up for the slow summer! Fishing is great all over the lake. With the lake at about 85% of capacity, water is low but cooling off with the weather. With uncertain weather predicted for the next several days,now might be the time to consider a visit. Use that intermediate line to present the standard array of Henry’s Lake patterns. Also trying a two-fly rig consisting of a small leech pattern and an attractor such a gold crystal. Word that fishing is improving has gotten out, so expect crowds at the easy access place such as the state park and county boat dock.  And if you are lucky enough to find a spot with excellent fishing,expect to see fellow anglers congregate around you.
