Fishing Conditions

April 12, 2021

The stone has been hit or miss these past couple days. Nymphing has been your best bet to rack the numbers up, and streamers have been working on the right days.  If you plan on nymphing you can keep it simple with; rubberlegs, worms, pheasant tails, eggs, and your favorite midge pattern. We find that water selection is more important than bug selection this time of year. The majority of the fish are still feeding in those slow deep runs and tail outs.  The water has been green on most days so dont forget to fish your bugs that have a little flash in them. Black, olive, and white streamers have been working the best for folks out there. Switch up your sizes until you find what they want to eat that day. With warmer days ahead of us blue wing olives should be showing up here soon. The best fishing for these little dries is in the back eddies and soft edges of seams. Keep an eye on flows. A little rain or warm weather can get the mud pumping. We are in window season on the stone. A few cold days will have the water looking great and fishing well, and a few warm days may muddy it up quickly. Feel free to call the shop if you need a clarity report.
