A major watercourse of north-western North America, Yukon River flows through the Yukon territory in Canada. The source of the Yukon River in British Columbia and its drainage area totals up to 832700 square kilometers.
The course of Yukon River
The Yukon River is fed by four principal tributaries in Canada, namely the Teslin River, the White River, the Pelly River, and the Stewart River. In Alaska, the branches include Tanana, Porcupine, and Koyukuk rivers.
Except for when it is swollen due to the spring waters, the Yukon river is shallow and slow-moving. The river can be divided into two regions. It rises in the upstream of its confluence with the Porcupine river while it is relatively flat over the remaining area to the Bering Sea.
Yukon River is bordered by beautiful mountains and covered with wooded islands. The valley turns narrow past Dawson and then widens when it enters Alaska into a broad plateau better known as ‘Yukon Flats”.
History of the River
According to several stories, birchbark canoe was formed on the shores of the Yukon River, and from there, it widens into Lake Laberge’s south end. In addition to this, many indigenous people traveled the river with rafts and mooseskin boats such that they could contain entire households.
To harvest fish from the summer runs in early summer and late spring, the indigenous people moved to fish camps. They built fish weirs using stones to hammer posts that trapped salmon. Salmon were then forced to move along the length of weir looking for a way through. When the weir was opened, the fish baskets would capture the salmon.
One of the most historic fish traps was located on an island at Three Way Channel. There were also times when the Yukon river changed its course, leaving the area too dry to be used for fishing.
The Klondike Gild rush of 1896 transformed Yukon and the river both, which in turn increased steamboat traffic and also the number of newcomers in the area. The primary mining operations were carried out on the tributaries of the Yukon River. In 1942, the Alaska Highway was completed, and it reoriented the activity away from the river in central Yukon.
The Yukon River continues to remain central for indigenous landscapes in Yukon, and it serves as a popular tourist destination too for the people who are interested in wilderness canoe trips. There are many visitors who, in every few years, paddle down the Yukon River to the biannual Moosehide Gathering and the Dawson City Music Festival.
Environmental Concern of Climate Change near Yukon River
Ever since the late 20th century, climate change has been causing the river ice to break even before spring. This leads to natural hazards that cause damage in the city like the ice-jam floods, which historically damaged the Dawson city.
Every year during fall, sewage from Whitehorse is discharged into the Yukon River, where it joins wastewaters of other small communities like Dawson. Increased contaminant levels have been observed in fish of Lake Laberge, Burbot, Lake Trout, and Northern Pike.
9 Crazy Facts About Yukon River
1. What’s in the Name?
Yukon has got its name from the Gwich’in language. The name Yukon means ‘great river’ which can be seen through various aspects of the Yukon River.
The source of the river is situated in the northwest part of British Columbia from where it proceeds to flow through Yukon, then into Alaska. Finally, it empties in the Bering Sea at the Yukon Kuskokwim Delta.
2. Length of the River
The length of the Yukon River is around 3190 kilometers. This makes it the longest river in Yukon and Alaska. It is also the third-longest river in North America.
To be precise, 2040 kilometers of the river are in Alaska, and the remaining 1150 kilometers are in Canada. The average flow of the Yukon River is 6430 cubic meters per second.
3. Yukon Kuskokwim Delta
It is a river delta situated where the Kuskokwim and Yukon rivers empty in the Bering Sea, which is on the west coast of Alaska. It is approximately 129500 square kilometers in size, which makes it one of the largest river deltas in the world.
An interesting fact is that it is even more significant than the Mississippi Delta, and can be compared to Louisiana state of the U.S. This delta mostly consists of tundra and is protected under the Yukon Delta National Wildlife Refuge.
4. Drainage Basin of Yukon River
The watershed or the drainage basin of the river covers approximately 832700 square kilometers of North America. It is the fourth-largest drainage basin in the continent and is unbelievably larger than Texas by 20 percent.
Until the mid-19th century, this area was in control of North American Indians. It was also one of the main ways through which people traveled during the Klondike Gold Rush of 1896-1903. The paddlewheel riverboats were a dominant form of transportation during the 1950s when the Klondike Highway was being completed.
Big Salmon, Teslin, Stewart, Pelly, Porcupine, Klondike, and Koyukuk are the north bank and main-east tributaries. The south bank and west tributaries are Tanana, Takhini, and White. In 1867, after the United States purchased Alaska, the assets of the Russian American companies were acquired by the Alaska Commercial Company, and several posts were constructed at various locations on the Yukon River.
Despite the river being so long,
