Much of the West has lower than normal snow pack. With normal or above normal snowfall many waters sustain high flows through some of the best hatches of the year. Years like this year (2012) should bring great hatches with flows low and clear enough to take advantage of some of the early summer hatches. The down side of a low water year is late summer, which often brings low, warm flows and tough fishing. Make time to get out early this year, after all, most of us have some time to make up from last years summer-long high flows!
Below are a couple of pics of one of several great early summer hatches, the famous Salmonfly or Pteronarcys. These are big, meaty and a bit prehistoric looking but Trout love them in all forms. Adults are only around in late spring/early summer but the nymphs are available to Trout year round.
Salmonfly nymphs are often mistakenly called Hellgrammites. Hellgrammites are really the larva of a Dobsonfly. Both insects are large and dark in color in their nymphal form, but not terribly similar otherwise. Regardless of what you call them, Pteronarcys Stoneflies bring the big fish to the surface!
