Boulder River

Fishing Conditions

April 12, 2021

The boulder runs cold this time of year. There are a few fish to be had on nymphs throughout the afternoon, but the bite is a little slow and the fish are a little lethargic. A big stone down to a small midge has been the best rig as of late. As always, be careful wading this river still as the water is cold and the rocks are always slippery.
