Damselflies are bringing action on several places around the lake. Try in front of creek mouths including Targhee, Howard and Duck . If these locations get crowded look for channles in the weeds and for spring holes to try your luck.
The lower river has entered the usual summer doldrums. So go to the upper river for best fishing. Box Canyon offers good nymph fishing with you favorite small bead head patterns or medium sized rubber legs. On the Harriman-Last Chance reach the brown drakes are winding down, so spinners and caddis bring best evening action. PMDs bring mid day action with emerger patterns producing best. Later in the afternoon flavs emerge and bring action.
With green drakes passing their peak, start looking for flavs. Brown drakes are making for great evening fishing, especially on the lower part of the Harriman reach. Evening caddis and AM PMD spinner falls are going on everywhere on the river.
With 550 cfs coming out of Mackay Dam wading remains tough in the river below. Best fishing is in or on just below Copper Basin right now. Look for caddis, PMDs, sallys, golden stonefly and traditional dry patterns to bring action.
To be sure, midging under an indicator will get you action on all reservoirs. But we have reports of fishing taking adult damselflies on the surface on all reservoirs, even on days with some wind. So now is the time to get your “dry fly reflexes” tuned up before the gulper season begins.
Tim passed on some good info on Teton River and the South Fork tribs yesterday. Take his comment about warming water seriously, because many small streams will be impacted during what looks like a very warm dry summer. Now is a good time to look at the numerous smaller streams we have in the area and to consider a visit to some. Here is a “laundry list” of some to consider. Robinson Creek, Conant Creek, all Salt River tribs in Idaho, Bear Creek, Beaver Creek, Little Lost River and Sawmill Creek, Medicine Lodge Creek, Portneuf River, Buffalo River, Willow Creek, and Warm River are at their peaks for good fishing right now. The Blackfoot River above the reservoir opened to fishing two days ago, and you should consider a visit to it quite soon. The best is yet to come on the lower Blackfoot River, Big Elk Creek and Bitch Creek. That’s is quite a list of waters to give details on here. Contact us one way or another for details on fishing these. We offer solid information on all. Several will surprise you with size of fish, and for sure you will like the solitude.
With the Firehole River warming up, everything else is shaping up. Caddis and PMDs (AM spinners, mid day to afternoon emergence) are making the Madison River in the Park a destination. Brown Drakes on the Gibbon River meadow reaches and on Duck Creek should be on your “to go” list for evening fishing. Green drakes are coming off in the meadow reaches of the Lewis River, below and above Lewis Lake. The Ashton-Flagg Road is open giving access to Beula Lake. Fall River Basin streams remain high because of snow pack remaining on Madison and Pitchstone plateaus. A bunch of us carried float tubes down Delacey Trail to Shoshone Lake last Saturday. Getting out on the lake in those tubes was a blast with juvenile macks, browns and brookies responding to small leech patterns presented on full sink lines. We had to place to ourselves!
Following is a note from the Henry’s Fork Foundation concerning the ongoing reconstruction work at Ashton Dam. In the meantime fishing conditions and fishing success should remain good.
At the Ashton Dam reconstruction project, they are having problems with the rubber seal over the upstream coffer dam coming loose, resulting in some additional sediment moving downstream. To fix this problem, they need to send divers down to re-anchor the rubber blanket. Since this work is being done next to the dam bypass tunnel, they will need to partially close the tunnel while they do the work. However, as this is peak irrigation season, they have to balance this work with downstream irrigation needs. The result will be some major fluctuations in Henry’s Fork flows below Ashton Dam throughout the day. Flows could fluctuate from 1200 cfs up to 3000 cfs, and this fluctuation may happen four times that day. Idaho Fish and Game will be monitoring things that day.
Bottom line, Monday July 9th will be a day you don’t want to be fishing below Ashton Dam.
