Typical median summer flow is between 200 and 300 cubic metres per second (7,100 and 10,600 cu ft/s), whereas during spring run-off, the median flow is 1,050 cubic metres per second (37,000 cu ft/s), but the river could swell anywhere from 400 to 2,400 cubic metres per second (14,000 to 85,000 cu ft/s). Lowest flow conditions occur in March with

189-527: Is a popular destination for canoe camping . A new 276.6-square-kilometre (106.8 sq mi) aquatic reserve is being considered that would protect 126 kilometres (78 mi) of the Ashuapmushuan River, including its floodplain and valley slopes. The reserve prohibits logging, mining, and hydro-electric development, while protecting critical landlocked salmon habitats, biodiversity, and sites of archaeological interest. The name Ashuapmushuan, which

243-491: Is just east of Lake Mistassini on the Rupert River . The vestiges of the post are considered some of the most valuable and best preserved relics from the era. After the fur trade, the Ashuapmushuan River was used by logging companies to drive logs downstream. The Ashuapmushuan River and its tributaries provide spawning grounds and habitats for landlocked salmon ( Salmo salar ouananiche ). Newly hatched salmon remain in

270-688: Is the second most important tributary of the Moise River after the Nipissis , which drains 4,196 square kilometres (1,620 sq mi). The proposed Moisie River Aquatic Reserve would include 115 kilometres (71 mi) of the Aux Pékans River.

378-499: The Aux Pékans and Carheil rivers for the SM-3 plant. As well as changing the hydrological regime, water temperature would be affected, an important factor in the habitat quality for Atlantic salmon . The report found that the Moise River would become slightly warmer, with less change further downstream. An earlier study has also estimated the impact if some of the diverted water was returned to

405-515: The Canadian provinces of Quebec . It starts at the outlet of Lake Ashuapmushuan , and flows first in a north-easterly direction for about 30 kilometres (19 mi) whereafter it continues south-east to Saint-Félicien . There it drains into Lac Saint-Jean of which it is the third largest tributary after the Peribonka and Mistassini Rivers . The river is 181 kilometres (112 mi) long but its source

432-659: The Mishtashipu, or Moisie. The Innu people of Mani-Utenam at the mouth of the Moisie were concerned about the increase in methylmercury and decrease in the flow of the Moise, and the effect on the 12,000–35,000 salmon that entered the river annually. However, the Innuat of Uashat to the west in Sept-Îles tended to favor the project. A report published in 1994 discussed the impact of diverting

459-582: The Moisie further down. Calculations were made of the effect on the Moisie estuary if one of the embankments on the Carheil and Aux Pekans were to fail. The flood wave would give a maximum discharge of about 24,600 cubic metres per second (870,000 cu ft/s), but because both embankments had low storage capacity, discharge would return to a flow rate of 5,000 cubic metres per second (180,000 cu ft/s) within about five hours. Water would rise by 2 to 5 metres (6 ft 7 in to 16 ft 5 in) in

486-526: The Pékans River south of Fermont. In August 2015 a limit of 10 tonnes was placed on vehicles crossing the bridge. The Ministry of Transport was working on a replacement structure, due to be commissioned in summer 2016. The river flows in a generally SSE direction, then near its end turns to the NE and enters the Moise River from the right. The Pékans drains an area of 3,419 square kilometres (1,320 sq mi) and

513-579: The Quebec Council of Ministers approved two decrees granting full legal protection as aquatic reserves to the watersheds of the Moisie River down to 25 kilometers from Sept-Îles, and the Ashuapmushuan River down to Lac-Saint-Jean. The Moisie reserve included protection for the Carheil and Aux Pékans, which were not to be diverted. Rivi%C3%A8re-Mouchalagane, Quebec Rivière-Mouchalagane

In 1917, the Commission de géographie officially adopted the modernized spelling of Chamouchouane . The Ashuapmushuan basin is part of the Central Laurentians in the natural region of the Lake Manouane Depression. The river is enclosed in narrow valleys for a large part of its course, with powerful rapids and

729-479: Was not officially adopted until 1982, is an Innu word meaning "place where one lies in wait for moose". The river was however first called Necouba by Louis Jolliet in 1679. This name was also used by Jean-Baptiste-Louis Franquelin and Guillaume Delisle in 1686 and 1703 respectively. But in 1732 surveyor Normandin considered this an error, who referred to the Necoubeau as a tributary to Lake Ashuapmushuan that
