Kremmling (Pumphouse) fishing report
Updated November 7, 2026.
Flows are low, about 200 cfs at Kremmling, with 3 feet or more of visibility. That is very skinny for floating, so get out and wade.
Work the riffles into drop-offs and boulder seams with Pat's Rubber Legs, small midges and Baetis nymphs, and swing streamers for the browns.
