Fly Fishing On The Stillwater River In Montana
The Stillwater River originates in the Absaroka-Beartooth Wilderness near the Wyoming state line and Yellowstone National Park boundary. It flows for a total of about 70 miles, first through Custer National Forest between the Absaroka Mountain Range and the Beartooth Mountains. From there it flows through a mixture of prairie and forest country to its confluence with the Yellowstone River. Fly fishing the Stillwater River is fast, pocket water fishing that usually provides a lot of action.
The Stillwater River is probably the most misnamed river in the World. Whitewater River would be a better name for it. It is a mountainous, fast-flowing, freestone stream. This is a beautiful river that is not heavily fished. It has a good population of cutthroat, rainbow, brook and brown trout.
Access to the upper section is great but in a wilderness area that does require hiking into. Horseback trips can also be arranged. Access outside the wilderness area is also good. Many public access areas, roadside pulloffs and bridges provide access.
The upper section of the river contains mostly brook trout and cutthroat trout. Rainbow and Cutthroat are plentiful in the middle section of the Stillwater River. Brown trout as well as rainbows and a few cutthroat are more common in the lower section.
Much of the Stillwater River consist of white water class rapids. Floating any part of the wilderness section isn’t advisable. Fast water rapids are plentiful even when the stream leaves the wilderness area. Below Nye, the river tends to slow down but is still very fast flowing water with lots of rapids. Unless your highly experienced with this type of water, you shouldn’t attempt to float it.
Summertime water levels slow the flow down but presents other dangers in the form of rock outcroppings. It’s more suitable for smaller inflatable rafts or kayaks. The lower section of the Stillwater River is more manageable.
Trout Food and Trout Flies:
The Stillwater has quite a few species of aquatic insects but most of them are clinger nymphs. There are several species of stoneflies including Little Winter stoneflies, Little Yellow Stoneflies, Salmonflies and Golden Stoneflies. These hatches always produce a lot of action but it requires being there at the right time and place. All but the Little Yellow Stonefly hatches are short in duration at any one point along the stream.
There are several different species of mayflies including Blue-winged olives, Pale Morning Duns, Western March Browns, Yellow Quills, Ginger Quills, Callabaetis, or Speckled Wing Quills, Tricos and others. You can always call or email us for information on the status of the hatches.
There are a several species of caddisflies including Green Sedges, Short-horned sedges, Spotted Sedges and October Caddis. The first ones to hatch in the late Spring are Little Black Caddis, or American Grannoms. During the summer and early fall, caddisfly hatches and egg laying activity are often the only thing happening. You need to fish the egg laying part very late in the day, until it is almost dark.
During the warmer months of the year, don’t overlook the terrestrial insects, especially ants and beetles. These are mostly carpenter ants and Japanese Beetles. There are also some grasshopper along some parts of the stream.
Sculpin are very plentiful. So make sure you have some Perfect Fly imitations of them. We have the Brown and White Belly Sculpin and Olive and Black Matuka Sculpin that work well for this stream.
One of the reasons the Stillwater River isn’t a more popular destination is the numerous other trout streams in the same general area of Montana. If that were not the case, it would be a highly popular stream.
