Yellowstone Park, May 30th, 2023

True to usual, the Firehole River provides the best fishing. Running a bit high, but cool promotes the insect activity, so caddis, PMD, BWO life cycle patterns bring action. Do not overlook swinging soft hackle patterns such as partridge and olive, partridge and orange, Syl Nemes’s suggestions, etc. A few large post spawning rainbows are in the Madison River heading back to Hebgen Lake so streamers should bring some action in such places as the Barns Holes and Baker’s Hole Campground. Caddis and PMDs are making and appearance along the river.

Duck Creek is over its banks and flooding the meadow. The Gallatin River is flowing high and discolored.

It will be a while before the Fall River Basin area can be approached. The Cave Falls Road is closed beyond the Horseshoe Lake turn-off and the Ashton-Flagg Road is closed east of the Jackass Loop west of Calf Creek Hill.
