Fishing Conditions

January 11, 2021

The Upper River is mostly frozen with the cold evenings. The lower river is really cold. 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. The Brown trout spawn is over but it's still good to look for redds near town to avoid.
