We are officially transitioning from spring mode into summer on the Bighorn.  Emergences of BWO’s and Midges have all but wrapped up, water temperatures are on the rise, rainbows are starting to move off their redds and trout are moving up into faster water riffles.

Water temperature yesterday afternoon at 3 mile access was 48 degrees and down river near  Bighorn Access water temperatures were around 53/54 degrees.  Water temperatures in the upper 50’s should trigger the start of our summer hatch cycle. PMD’s, Yellow Sallies and Caddis, both tan and black.

For the past 3 months the trout have been in tune almost exclusively, to the rhythm of the midge and bwo hatch cycles and daily emergence times.  With these spring hatches over and summer hatches yet to get underway trout will seek out other food sources available.  On a tailwater such as the Bighorn, we are talking about scuds, sow bugs, worms and midge larva/pupa underneath.

For anglers seeking out surface action, blind fishing with your smaller terrestrials such as ants and beetles is never a bad idea this time of year.  Nymph fisherman should find the right color sowbug for the day, prospect with the worm, play around with midges and look for pmd nymphs to start showing up in stomach samples sooner than later.  Remember, last year there was a long gap in time from when the trout started eating pmd nymphs until they started taking duns and emergers on the surface.  When they get on the pmd nymphs it is some of the best nymph fishing of the year.

Embrace this transition period, trout go on the feed and it marks the on set of summer. The river is in great shape  at 1980 cfs, with lots of bugs and the trout are fat and happy.  Get out and fish!
