Fly Fishing The Red Rock River in
If your looking for some solitude in Montana and plenty
of trout, it isn't difficult to find. Fly fishing the upper part
of the Red Rock River will accomplish that for you. The
headwaters of its tributary streams start out at over
9,000 feet near the continental divide close to the
Idaho and Montana state line in Southwestern Montana.

The Red Rock River holds a good population of trout in
two places along its seventy mile long course. Its upper
headwaters is a small stream but it holds plenty of
cutthroat and some grayling. Although it is very remote
it's a great small stream to fish. Access is not a problem
thanks to the public land it flows through.

Fishing is prohibited on both upper and lower Red Rock
Lakes as well as the river between them. From there it
flows through Red Rocks Lakes National Wildlife Refuse
and on into Lima Reservoir.

The tailwater below Lima Reservoir holds a good
population of both brown and rainbow trout. Fly fishing
the Red Rock River in this section can be done from a
canoe or small pontoon type drift boat. The river flows
through mostly private land and access is limited to the
two bridge crossings. The rainbows average about 12
inches but the browns grow much, much larger.

Fly fishing the Red Rock River can be good any day of
the season.
Springtime is a prime time for fly fishing the Red Rock
River except during runoff..
Summertime is the most popular time to fish the stream.
Fall is the best time to fish the tailwater section of the
Red Rock River. The brown trout spawn in the Fall and
are easier to catch.
