The Bighorn has been fishing fair. Flows are around 2200 near St. Xavier with water temps coming in at 42 degrees. The cooler nights have the weeds breaking off so you will see some debris still, but water clarity improving. No hatches coming off at the moment but black ants in the soft water could bring some fish to the surface. Nymphing will get the job done with crustations, squirmy worms, sow bugs and scuds. Streamers will get you quality fish over quantity.
