The storm will make back country roads along the river a bit difficult. But this situation is only temporary, and days of good fishing will remain for weeks to come. Windfall of this early storm is that it begins the water storage year in the drainage as snow will likely stay at higher elevations, and it adds acre-feet to in-line reservoirs. Flow in the river is at normal levels for this time of year (3540 cfs at Irwin, 4140 cfs at Heise,1790 cfs at Lorenzo) and usual activity (presenting BWO, mahogany dun, midge life cycle, double nymph rigs, streamer patterns) continues.
A tip from Jimmy G. is that on seeing rising fish in good numbers, presenting soft hackle patterns of taking could bring happy results.
