Kingfisher Fly Shop had this to report for all of the Rock Creek anglers:
Ha! not so much. Blowwwwwn out, though the flows have dropped off.The first wave of run off is here. The upper end of Rock Creek might still be doable, but will still have alot of melting to do. The Missouri, Browns Lake, Harpers Lake, Beavertail pond, Warm Springs, and Frenchtown Pond are your best options.
HATCHES: baetis, March browns, grey drakes, skwalas
