Harriman East Fish Pond, non-motorized, is scheduled to be stocked with rainbow trout this week. It’s a good action because up to now it appears that there are very few or no trout in the pond. Horseshoe Lake is schedule for rainbow stocking next week. The same is for Teardrop Lake, but will the road be open?
Chesterfield and Twenty-Four Mile reservoirs have been stocked. We have no fishing success information for these as well as for Treasureton Reservoir. Daniels Reservoir has been fishing fairly well, and action at Springfield Reservoir has been picking up. Midge pupa patterns under an indicator work after the taking depth is found on both waters. Damsel fly, leech patterns and small fly rod jigs also produce on these.
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.
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.
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.
Not much going on here. Many locations are still iced over or difficult to approach. Springfield Reservoir has been slow fishing lately. Some action can be had through presenting midge pupa under an indicator after finding the taking depth.
The best chances for action remains at Daniels and Springfield Reservoirs. Presenting damselfly nymph and midge pupa patterns, both under indicators, seems to work best. Slow-stripping small leech and BLM patterns also brings responses from resident trout.
Daniels Reservoir currently remains the best location for action. Midge pupa at the taking depth and underneath an indicator as well as damsel fly nymph patterns fished the same way or slowly stripped seem to work best. The same approaches plus presenting small leech patterns is bringing action on Springfield Reservoir. Chesterfield and twenty-Four Mile Reservoirs have been slow fishing all season. Because of introduced bass, plans are taking shape to poison Hawkins Reservoir to return it to a trout fishery for which it is best suited.
Compared to our numerous more renowned still waters Horseshoe Lake is almost on the “Where’s That?” list. It is remote, not frequently fished, has (at best) primitive facilities, and hosts no self-sustaining salmonid population. But Horseshoe Lake has an attraction no other eastern Idaho water can boast: Montana grayling. The lake has no inlet and outlet needed, in suitable condition, for their spawning. Thus its stock of grayling is replenished each year from a Montana hatchery ( rainbow trout released here come from an Idaho hatchery). A resident grayling here is a “braggin’ fish” if it grows to a foot long, nevertheless they are beautiful to behold, and because of their near endangered status a privilege to catch and release. Resident rainbow trout, also stocked, outnumber them here on a near 10:1 basis, so patience is required to encounter one. The lightest weight in fly rod systems is most appropriate for presentations, and “small” applies to fly patterns. Standard nymph patterns with or without bead heads and soft hackled patterns, both in size 16 or smaller and presented on a floating line and long slender tippet are good choices for achieving interest from grayling. However during wind-free times when rise forms are numerous, nothing beats presenting small (#18 and smaller) dry patterns such as adams, light cahill, and purple haze, all in more visible parachute form, to these fish. You may have to get through several rainbows of similar size before one of these strikes. That makes catching and releasing one even more of a privilege.
Horseshoe Lake is about twenty-five miles east of Ashton. Its road, winding northeasterly, leaves the Cave Falls Road about a mile east of the LDS Church’s Rock Creek Girl’s Camp. It’s a fairly rough road with pot holes, rocks, and lots of dust. Tires in good shape and cautious speeds are required. There are a few non-motorized boat launching sites at the northwest corner of the lake, and flotation devices are most suited for fishing. The best chance for action is through locating in front of the west side lily pad beds where fish cruise looking for emerging aquatic insects. Good Luck!
The gulper event on Hebgen Lake remains the best still water fishing in the region. The gulper event on Beula Lake in Yellowstone Park is also very good. Gulper activity happens on any still water when callibaetis mayflies emerge in abundance. Sand Creek Pond #4, Elk, Wade, Springfield, and Horseshoe Lakes can host good ones, but timing is important because these can vary in time water for water. On some of these, good emergences begin in Mid-July, on others gulpers last well into September. Also time of day can vary. The famed Hebgen event happens during AM hours, but on other locations afternoons offer the best gulper fishing. Forget about gulper fishing anywhere when wind comes up, and we have had plenty of that this season.
