Madison River 1890 CFS @ Cameron, 2360 CFS below Ennis Dam
The Lower Madison has been quite good this week. Lots of bugs around: caddis, a few PMD's, some small olive stones, and some straggler baetis. The crawdad is still getting fish, and the dry fly fishing with caddis patterns or larger attractor patterns has been quite good in the clouds. The Upper is up a little, and there is some color in the water, but the nymphing is still quite productive. Worms, mayfly nymphs, stonefly nymphs, and streamers are all producing fish.
Missouri River 4070 CFS below Holter Dam
Things are still good on the Missouri River. The spring hatches (baetis and March Browns) are starting to fade a bit, but the early summer bugs are right around the corner. Some PMD's and caddis have been spotted, not in great numbers mind you, but they have to start soon. Probably this week. Nymphing has been great with a variety of mayfly nymph patters, worms, and crawdads.
Yellowstone River 8600 CFS @ Corwin Springs
The Yellowstone continues to climb, but it is not climbing much. The flows have been around 8600 all week, and if you are comfortable rowing at the higher flows, I bet you can catch some fish over here right now. I would suggest staying above the Shields and the town of Livingston, as the water will be a bit cleaner above. Sculpin and bait fish patterns.
Gallatin River 2680 CFS @ Gallatin Gateway
The Gallatin is still quite high, and totally punched out. Completely blown.
Jefferson River 3590 CFS @ Twin Bridges
The Jefferson has been slowly climbing all week, but in my opinion, not enough to hurt the fishing. The gradual climb is not anywhere as disruptive as the quick spike. It is definitely dirty, but there was at least 2 feet of visibility at Three Forks.
