Missouri River (4480 CFS below Holter Dam) As usual, the Missouri River has been the most consistent option this spring. The spring mayflies are just about finished, but the caddis have arrived in the canyon. Still some fish looking for BWO's, but the March Brown's have gone for the year. Nymphing has been great with the usual spring fare- worms, scuds, mayfly nymphs, and some caddis pupa. Upper Madison River (1200 CFS @ Cameron) The Upper is a bit off color below the West Fork, but definitely clear enough to fish. Still some BWO's and March Brown's up here, and caddis as well. Nymphing and streamer fishing have been very good, if you happen to get out there without a 20 MPH North wind. Lower Madison River (1890 CFS below Ennis Dam) Clarity on the Lower is just perfect, and the fishing has been great. Caddis and small olive stones are flying,but the fish are really eating crayfish and sculpins (surprise,surprise). The fishing here should hold up for quite a while, and as with every spring, could be the best option close to Bozeman. Gallatin River (2170 CFS @ Gallatin Gateway) The Gallatin River is on the rise once again, and this should not come as a shock to anyone. We have been absolutely socked in with rain the last few days, and that water has to go somewhere. Jefferson River (3420 CFS @ Twin Bridges) The Jefferson is on the rise once again, and will not be a solid option for a while. Yellowstone River (6540 CFS @ Corwin Springs) After a brief drop in flows, during which the Yellowstone was fishing well, the river is on the way out again, and probably will remain as such for quite some time.
If you need to fish right now, which I get, head to one of the numerous tailwater fisheries and enjoy the clear water.
