The Fisher River is a tributary of the Kootenay River (spelled Kootenai in the United States) in the U.S. state of Montana. The Fisher River properly begins at the confluence of its two main tributaries, the Pleasant Valley Fisher River and the Silver Butte Fisher River. Of the two tributaries, the Pleasant Valley Fisher River is the larger and is sometimes considered part of the Fisher River proper. A variant name of the Fisher River is Pleasant Valley River, and a variant name of the Pleasant Valley Fisher River is Fisher River.^[1]^[3]

Course

The Pleasant Valley Fisher River originates in the Salish Mountains near Little Bitterroot Lake in Flathead County, Montana and flows northwest through Lost Prairie valley. It is joined by Pleasant Valley Creek just before crossing into Lincoln County, Montana, where the river flows southwest, through Loon Lake and Little Loon Lake, to join the Silver Butte Fisher River, forming the Fisher River proper.

Silver Butte Fisher River originates in the Cabinet Mountains and flows about 14 miles (23 km) northeast to join the Pleasant Valley Fisher River.

Downriver of the Pleasant Valley and Silver Butte confluence, the Fisher River flows generally north, picking up several tributaries including West Fisher Creek, Cow Creek, Wolf Creek, Fawn Creek, and Buck Creek, before emptying into the Kootenai River a few miles below Libby Dam and a few miles above Libby, Montana.^[5]

Part of Pleasant Valley Fisher River is paralleled by U.S. Route 2. The BNSF Railway's line through Flathead Tunnel and Marias Pass follows part of the lower Fisher River and its tributary Wolf Creek.

Much of the land of the Fisher River basin is privately owned, but a large portion lies within Kootenai National Forest.

Natural history

The Fisher River's drainage basin has experienced higher levels of mining and logging operations than other nearby tributaries of the Kootenai River, such as the Yaak River and Moyie River. This has resulted in water quality impairment, stream channel degradation, and a relatively high amount of fine sediment in the water.^[6]

In the late 1960s, the Great Northern Railway (BNSF today) was rerouted along the lower ten miles (16 km) of Fisher River and most of Wolf Creek, a tributary. The streams were channelized and shortened during this time. Portions of Pleasant Valley Fisher River have also been channelized and shortened along U.S. Highway 2. All of these things negatively impact fish habitat in the Fisher River basin.^[6]

History

According to the USGS, variant names for the Fisher River include: Bank Creek, Ma-su-la Creek, Pleasant Valley Fisher River, and Pleasant Valley River.^[3] Variant names for the Pleasant Valley Fisher River include: Bank Creek, Fisher Creek, Fisher River, Pleasant Valley Creek, and Pleasant Valley River.^[1] Variant names for the Silver Butte Fisher River include: East Fisher Creek, Fisher Creek, Galena Creek, Silver Butte Creek, Silver Butte River, West Fisher Creek, and West Fork Fisher Creek.^[7]

The Clark Fork, or the Clark Fork of the Columbia River, is a river in the U.S. states of Montana and Idaho, approximately 310 miles (500 km) long. It is named after William Clark of the 1806 Lewis and Clark Expedition. The largest river by volume in Montana, it drains an extensive region of the Rocky Mountains in western Montana and northern Idaho in the watershed of the Columbia River. The river flows northwest through a long valley at the base of the Cabinet Mountains and empties into Lake Pend Oreille in the Idaho Panhandle. The Pend Oreille River in Idaho, Washington, and British Columbia, Canada which drains the lake to the Columbia in Washington, is sometimes included as part of the Clark Fork, giving it a total length of 479 miles (771 km), with a drainage area of 25,820 square miles (66,900 km²). In its upper 20 miles (32 km) in Montana near Butte, it is known as Silver Bow Creek. Interstate 90 follows much of the upper course of the river from Butte to Saint Regis. The highest point within the river's watershed is Mount Evans at 10,641 feet (3,243 m) in Deer Lodge County, Montana along the Continental Divide.

The Pend Oreille River is a tributary of the Columbia River, approximately 130 miles (209 km) long, in northern Idaho and northeastern Washington in the United States, as well as southeastern British Columbia in Canada. In its passage through British Columbia its name is spelled Pend-d'Oreille River. It drains a scenic area of the Rocky Mountains along the U.S.-Canada border on the east side of the Columbia. The river is sometimes defined as the lower part of the Clark Fork, which rises in western Montana. The river drains an area of 66,800 square kilometres (25,792 sq mi), mostly through the Clark Fork and its tributaries in western Montana and including a portion of the Flathead River in southeastern British Columbia. The full drainage basin of the river and its tributaries accounts for 43% of the entire Columbia River Basin above the confluence with the Columbia. The total area of the Pend Oreille basin is just under 10% of the entire 258,000-square-mile (670,000 km²) Columbia Basin.

The Kootenay River or Kootenai River is a major river of the Northwest Plateau in southeastern British Columbia, Canada, and northern Montana and Idaho in the United States. It is one of the uppermost major tributaries of the Columbia River, the largest North American river that empties into the Pacific Ocean. The Kootenay River runs 781 kilometres (485 mi) from its headwaters in the Kootenay Ranges of the Canadian Rockies, flowing from British Columbia's East Kootenay region into northwestern Montana, then west into the northernmost Idaho Panhandle and returning to British Columbia in the West Kootenay region, where it joins the Columbia at Castlegar.

The Flathead River, in the northwestern part of the U.S. state of Montana, originates in the Canadian Rockies to the north of Glacier National Park and flows southwest into Flathead Lake, then after a journey of 158 miles (254 km), empties into the Clark Fork. The river is part of the Columbia River drainage basin, as the Clark Fork is a tributary of the Pend Oreille River, a Columbia River tributary. With a drainage basin extending over 8,795 square miles (22,780 km²) and an average discharge of 11,380 cubic feet per second (322 m³/s), the Flathead is the largest tributary of the Clark Fork and constitutes over half of its flow.
