Kechika River

The Kechika River is a tributary of the Liard River, about long, in northern British Columbia, Canada. The Kechika flows generally northwest through the northernmost section of the Rocky Mountain Trench before turning east to join the Liard, a major branch of the Mackenzie River system. The river's drainage basin is characterized by high glaciated peaks, boreal forest, and open tundra. With no settlements, roads or dams along its course, the Kechika is considered "one of British Columbia's finest examples of wilderness and undisturbed wildlife habitat."

Inhabited for thousands of years by the Kaska Dena, the Kechika was explored by fur traders in the 1800s and was one of the routes to gold strikes in the Yukon. The difficulty of accessing the remote Kechika country made it an unappealing location for European settlement. Today, the Kechika River basin includes a number of large parks and protected areas, most of which are administered under the umbrella of the Muskwa-Kechika Management Area, which includes almost the entire Kechika basin and parts of several adjacent river systems.

Geography

The Kechika River begins more than above sea level in the Sifton Ranges about south of Mount Slocomb. It flows north to the Rocky Mountain Trench at Sifton Pass, which marks the divide between the drainage basins of the Kechika and the Fox River, which flows southeast along the Trench into the Finlay River. The Kechika turns northwest down the Rocky Mountain Trench and flows through Dune Za Keyih Provincial Park and Protected Area, where it receives the Frog River from the west and the Gataga River from the east. Further downstream, it receives its largest tributary, the Turnagain River, from the west, then the Red River also from the west. After the Red River confluence the Kechika turns to the northeast and flows into the Liard River near the unincorporated community of Fireside, about southeast of Watson Lake, Yukon and northwest of Fort Nelson, BC.

The Kechika drainage basin includes about in BC's Stikine Region and Northern Rockies Regional Municipality. The main Kechika River valley sits between the Muskwa Ranges (part of the northern Rocky Mountains) to the east, and the Sifton, Thudaka and Kechika Ranges (all part of the greater Cassiar Mountains) to the west. The Cassiar Mountains in this area are higher than the Rockies and are extensively glaciated. The Turnagain River drains an area west of the Kechika Ranges, stretching as far as the Three Sisters Range at the edge of the Stikine Plateau. The southern part of the Kechika basin is mountainous, while the northern part, extending into the Liard Plain, is characterized by rolling hills and muskegs. The Kechika basin is bordered by the drainage basins of the Dease River to the west and the Rabbit, Toad and Fort Nelson Rivers to the east, all tributaries of the Liard. To the south are the basins of the Stikine River, which flows into the Pacific Ocean, and the Finlay River, which flows into the Mackenzie via the Peace and Slave Rivers.

Discharge

The primary source of water for the Kechika River is snowmelt, although there are also a few small glaciers that contribute water to the river. A stream gauge operated by Water Survey of Canada recorded discharge data at the mouth of the Kechika River from 1962 to 1995. The gauge recorded a mean annual flow of . Mean monthly flows range from a high of in June to a low of in February. The highest flow month on record was June 1964, at , and the lowest was March 1972, at . The highest flow year was 1974, with an annual mean of , and the lowest was 1978, with an annual mean of .

History

The Kechika River is within the traditional lands of the Kaska Dena people, whose ancestors have lived in the area for about 4,500 years. Although the Kechika is more navigable than most rivers in the northern Rockies, the Kaska traveled along the river via trails rather than canoes. The Kechika River valley was used for hunting, fishing and trapping (particularly for beaver), with major camps near the Kechika-Turnagain confluence, Graveyard Lake and Aeroplane Lake. The river is ''Tadahzeh''', "long inclining river", in the Kaska language. In the 19th century, the Sekani people were displaced west into the Rocky Mountain Trench as a result of First Nation territorial changes during the fur trade. In the Sekani language the river is ''Tah Chow Gàh'', ("big windy" or "windy valley"). The Altse Dene Tunna or Davie Trail historically ran up the Kechika River valley, connecting Kwadacha, on the Finlay River, with Lower Post, at the confluence of the Liard and Dease Rivers. The trail is named after Old Davie, a half-Sekani prophet who became known as a liaison between local tribes and European explorers.

The first white man to reach the Kechika River basin was Hudson's Bay Company (HBC) fur trader Samuel Black, who in 1824 ascended the Finlay River scouting northern BC for a route westward to the Pacific Ocean. At the confluence of the Fox River with the Finlay he noted "it heads at a pass two days' travel northward, whence a river flows northward into the Liard." Black never saw this northward-flowing river (which would be the Kechika), instead heading west into the Stikine Country and turning back at a stream that he named the Turnagain River, which flows northeast into the Kechika. In 1831, HBC trader John McLeod ascended the Liard River and in passing by the mouth of the Kechika River, correctly guessed that it was the outlet of what Black had called the Turnagain River, and so named the stream "Black's River".

The 1873 Cassiar Gold Rush was centered on a tributary of the Turnagain, the Cassiar River. Between 1873 and 1886, prospectors explored large areas of the Turnagain and upper Kechika River basins. Although the area is rich in minerals, no mines were ever developed along the Kechika River corridor. Minerals documented in the Muskwa-Kechika Management Area include "copper, lead, zinc, silver, barite, gold, tungsten, chalcopyrite, pyrite, dolomite, quartz crystals, malachite, aragonite, mica and azurite." Fur trappers and prospectors of the 1800s often called the Kechika River the "Muddy River" or "Big Muddy River" due to the heavy silt loads the river brought down in floods.

In 1898 the Klondike Gold Rush spurred interest in finding a route from Alberta to the Yukon. Inspector J.D. Moodie of the North West Mounted Police (NWMP) explored the Kechika valley as a potential route for prospectors traveling from Edmonton, Alberta. Hedley (1941) called Moodie's report "the first authoritative description of the region". Moodie's route followed the Peace River to Fort Ware (Kwadacha) and then followed the old Davie Trail through the Kechika valley up towards the Yukon. The "Old Moodie Trail" was considered one of the most difficult routes to the Klondike gold fields, compared to sea routes starting in Victoria, British Columbia and landing in northern BC or Alaska, and only a few prospectors successfully completed the trip. In 1900 a cattle drive to the Yukon was attempted via this trail from Vanderhoof, British Columbia and in 1905 the BC government attempted to improve the trail, though the effort was abandoned in 1907 due to high costs.

Moodie recorded the name as "Ta-ta-chi-ca" during his explorations of the region and later produced a map labeling the river as "Kachika". In 1914 Major E.B. Hart of the Royal Geographical Society noted that the inhabitants of the area pronounced the river with an 'e' rather than an 'a' sound and proposed the spelling "Kechika", which was officially adopted by the BC Geographic Division on March 3, 1925. However, as late as 1949 the river was still colloquially known as "Big Muddy".

In 1939, John Ogilvie "Skook" Davidson, a northern BC packer and guide, settled in the Kechika River valley and established Diamond J Ranch. For more than thirty years Davidson supported packing expeditions for geology and survey crews, as well as guiding hunting expeditions. Davidson helped scout the route for the Alaska Highway
