North shore of Hebgen Lake is fishing well for those presenting streamer and big woolly bugger patterns. Try big stonefly nymphs and rubber leg patterns below Hebgen Dam. Some rainbows remain in the South Fork of the Madison River estuary, and they will take any streamer pattern you present.
Beaverhead River is low, but fishing is good. Try cranefly larva patterns, streamers and woolly buggers in deeper waters.
Red Rock Creek in Red Rock Lakes Wildlife Management Area is closed to fishing through June 15th in order to allow grayling to spawn with minimal human interference.
