Presently Montana Fish, Wildlife and Parks Dept. has no plans for mandatory fishing closures other than those (2PM to midnight) on the Dearborn, Smith and Sun rivers. Best way to see closure details and if any new come into effect is to visit their web site then click on the Restrictions and Closures button. Hebgen Lake gulpers are providing good morning action.
Hebgen Lake gulpers are on-going for the still water guy, and Madison River giant stonefly hatch on going for the moving water guy. Try Madison Arm for gulpers. Try between Quake and Hebgen lakes for giant stoneflies. Expect company at both locations.
Migrating browns make for the best streamer fishing here. Best walk-in locations on the Madison River are between from Raynolds Bridge downstream, between Quake and Hebgen lakes, and in the river above Hebgen Lake to the Yellowstone Park boundary. Browns are migrating to spawning areas in the Beaverhead River. Float fishing is the best way to encounter these in the river below Clark Canyon Dam. Wait a few weeks for the peak of brown trout migration into the South Fork of the Madison River.
The Madison River is back to its fabled self for the time of year. The big stoneflies have arrived in the reach between Hebgen and Quake lakes, so fly-fishers are concentrating there. Below Quake Lake a great strategy is to concentrate on presenting nymphs (From rubberlegs to caddis pupa) in the AM, then with early PM warming switch to dry fly fishing where caddis and stoneflies of all sizes are bringing up fish. Don’t overlook presenting ants and beetles. Hebgen Lake trout seem to be taking midge pupa and some on the surface. Maybe they are getting in practice for the upcoming gulper season. Fishing on Clark Canyon Reservoir is improving but spotty. Midging seems the best approach. The Beaverhead River with a bit lower than normal flows offers some of the best fishing around with golden stones, PMD, and caddis bringing trout up.
