Fishing Conditions

August 20, 2018

The window on this has more or less closed. The Water is hot, the flows are all over the place, and the weeds and grass are really bad. the water temps have dropped over the past few days, but with warm weather in the forecast, they should jump back up son. The canyon has been well into the 70's. This is not a good temperature for trout. It is probably best to leave this river alone for a couple more weeks. If you do head this way, head out really really early. The water is coldest in the mornings, do not fish here in the evenings, the temperatures are lethal to trout. hoppers and droppers should find a few fish.
