Yellowstone Park Waters

Fishing Conditions

August 2, 2020

The water temps on the west side of the Park ( Madison, Firehole and Gibbon) have peaked above safe fishing temps. After the recent rains, the rivers in the northeast corner couldn't be in better shape. The Lamar is in between 500-600 cfs, these are the flows when it fishes the best and the water temps are good for Golden stones and Yellow Sally's. Slough Creek will have the most anglers but has enough water to accommodate everyone. Bust out your Goldens, Sallies and PMD's. Now that Yellowstone Lake is fully open, it's a good time to get out the power boat. Both the Cutthroat and Lakers will still be in relativity shallow water.
