Take it to the bank that because waters are now warming, it is time to go deeper or look for the coolest locations available in any still water location you fish. Fish will go deep looking for better concentrations of dissolved oxygen. It’s a good idea to have a reliable thermometer available when you visit a still water. Check water temperature a bit below the surface. When you see temperatures above the low to mid 60s, don’t expect the best fishing such location can offer. Late and especially very early in the day may be exceptions if water gets cooler.
Stick with “where to go” info we gave in the July 3rd report. All these streams remain good choices, but with warming weather, some will fade from the good fishing scene in a few weeks. We’ll keep tabs on these for making recommendations to you.
Good reports are coming in from Beula Lake where small beadhead and damselfly nymphs are producing. The Firehole River is done for good fishing until September. Some PMDs and lots’a caddis remain on the Madison River for evening fishing. Some evening brown drakes remain on Duck Creek and meadow reaches of the Gibbon River. Fall River Basin streams are shaping up with run-off about finished. Look for their green and brown drakes to begin emerging. Right now PMDs and sallies are just beginning to bring surface feeders on all Basin streams. The Gallatin river is also free of run-off and giving good PM fishing with active caddis and some golden stones.
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.
