Fishing Reports

Jimmy's All Seasons Angler / Fishing Reports (Page 17)

Big Lost River 10-17-15

The South Fork isn’t the only one having a significant drop in flow. Flow out of Mackay Dam was reduced yesterday from 150 cfs to 50 cfs today. It’s great for wading but not for fish. Midging will get you into the fish concentrated in holes and runs.

South Fork of the Snake 10-15-15

The flow dropped last night from 4600 cfs to 3100 cfs. We haven’t heard what the eventual winter flow will be but generally it is between 1,000- 1500 cfs by early November. We are seeing good hatches now of Blue Wing Olives and Mahogany Duns. The Streamer fishing has been best early in the morning and then again late afternoon until dark. With the cloudy cool weather coming this weekend we could see some very good dry fly action.

South Fork 10-13-15

All water properties are holding steady for the last five days.  Weather looks like it will be about the same for next several days. So look for continuation of current fishing success.

Derrick (208-529-8676) lost a brown and white pack pack at Fullmer this weekend.  It contained tackle and a cell phone. Please get in touch with him at number above if you found it or have info on it.

Still Water 10-10-15

Sand Creek Pond #4 produces early and late in the day if you try soft hackled flies  not far below the surface. Partridge and orange or partridge and olive are good candidates.  Chesterfield Reservoir, even with low water, is producing some fish responding to damselfly nymph patterns. Springfield Reservoir was planted not long ago, so expect it to be tough to get to big hold-overs. Midge pupa patterns under an indicator work if you find the taking depth. The same technique works well at Daniels Reservoir, but wading the discolored water line under breezy conditions is as good a technique as float fishing.

Henry’s Lake 10-10-15

Looks like fishing success now depends on the weather. These bright, cloudless skies do not result in the best conditions for fish to be active.  Nevertheless the lake is cooling as nights get colder. A recent day with fog and some wind produced some excellent fishing around the lake for some local enthusiasts, even during daytime hours. A variety of fly patterns presented on intermediate lines worked for them, and wading was as effective as boating. For now it looks like watching the weather to find overcast conditions may be the secret to success.

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.
