Fishing Reports

Jimmy's All Seasons Angler / Fishing Reports (Page 60)

Henry’s Lake 9-11-12

We’ve had reports of good fishing early in the last few days before the wind kicked in. Yesterday it was strong enough to send  many boats off the lake.  Creek mouths were good locations with Targhee Creek leading the pack and Howard Creek coming on.

Yellowstone Park 9-8-12

Browns have begun their migration out of Hebgen Lake into the Madison River and on up to spawning grounds in the Gibbon and lower Firehole rivers. The same will soon begin on Lewis River Channel and the Yellowstone  River. So break out the streamer patterns.  Cooling weather is beginning to improve fishing success on the Firehole River.  Trico activity is making for good fishing along the Madison River and in Fall River Basin.   So keep those trico patterns handy for a while.

Still Waters 9-8-12

Island Park Reservoir,  mostly on the west end,  has been drawn down to levels where sand bars and mud flats are exposed or close enough to the surface to present a hazard to boaters.  Nevertheless good fishing can be had near spring holes such as Grizzly Springs.  Getting there pretty much requires long distance boating, so be careful of the submerged conditions on the way there and back. When you get there, try bloodworm patterns under an indicator and experiment to find the taking depth.  Springfield Reservoir is producing for those folks presenting midge pupa patterns around spring holes.   Expect company on these and the few other still waters offering good fishing because so many such as Twenty-Four Mile, Daniels, Chesterfield and Condie have been drawn down to levels where conditions are unfavorable for fishing.

Big Lost River 9-8-12

The river below Mackay Dam is in great wading shape now. Trico spinners and egg droppers are still providing AM action.  Later it is on to terrestrial patterns and traditional attractors followed by caddis life cycle patterns.

Henry’s Fork 9-8-12

Now that cooler weather is here mayfly hatches,  though still significant, are not the only game in town.  If you tend toward the river in  Harriman State Park this time of year, a good strategy for presenting larger flies are long, drag free as possible, drifts.  Present in this manner around bank side cover, sweepers (which are relatively rare here), rocky shorelines, and timbered shorelines.  Terrestrial patterns are best for using this technique, and those, especially hopper patterns,  tied with traditional materials seem most effective within these.   Don’t expect to catch a huge number of fish using this strategy, but do expect to encounter some of the larger fish here.

Henry’s Lake 9-8-12

Fishing is picking up now. Creek mouths remain the place to go for action using mity mites, peacock leeches, crystal buggers and black coppers.  But with cooler weather here and more to come, fishing all around the lake should pick up even more.  Folks are concerned about the size of fish being caught, but the better news is that with so many fish in the lake there will be plenty for all anglers to enjoy.

Small Streams 9-8-12

It’s a tough time of year for fish in many of our smallest streams. We visited Jackknife Creek with 2-weight rods a few days ago, and became concerned with the low water we saw there.  The creek has a large drainage, but like so many smaller streams the dry, warm summer has limited surface water throughout the drainage. We managed to catch some beautifully colored cutts, but only in deeper runs and holes having water flowing through.  We originally intended to fish beaver ponds along the creek.  But these hosted huge algae blooms, thus fish were absent because of lowered dissolved oxygen.  Concerned that we would be stressing fish, we ended our fishing early.    Such an experience can be expected now on many of our smaller streams at the end of this dry summer.  Let’s hope for a good snow winter followed by a summer with more precipitation than this one to give trout populations better living conditions next year.

Henry’s Lake 9-4-12

Not much change since our last report on Henry’s Lake.  Fishing success is likely to pick up as we cool off, but that means visiting anglers will not diminish much.  Being such a great fishery it’s to be expected!

Yellowstone Park 9-4-12

Word has it that Hebgen Lake browns are coming into the Madison River above.  Now that it and other rivers in the drainage above are open, look for good fishing in the AM with trico spinners and egg layers followed by fishing with terrestrial patterns.  The Gibbon River will likely be better fishing than the Firehole River until further cooling takes place.   Tricos in the AM, terrestrial patterns later in the day and an increasing use of streamers is a good general strategy for fishing the Park this time of the season.

Henry’s Fork 9-4-12

If you venture to the Last Chance-Harriman State Park reach the fishing sequence is trico spinners and egg layers in the AM, flying ants later in the morning, terrestrials through the day to caddis in the evening. Not may anglers will be present, so you can pretty much choose your waters.    Flow out of Island Park Dam has dropped considerably making for easier wading conditions in Box Canyon.   Below Riverside campground go with terrestrial patterns along banks, and your favorite bead head nymph in deeper water.   Streamers should be effective below Coffee Pot Rapids and the best choice if you fish above Mack’s Inn.
