Hydrology

The watershed of Rimouski River covers an area of 1,635 square kilometres (631 sq mi) of which 98.6% are located in the Quebec and 1.4% in New Brunswick.^[3] The river has a Module of 30 metres (98 ft). The recorded maximum flow is 530 cubic metres per second (19,000 cu ft/s) and the minimum rate is 1.6 cubic metres per second (57 cu ft/s). It has a nivo-pluvial regime with a flood in early May and another smaller at the end of October.^[2] The river receives water from 29 streams, the main ones, from upstream to downstream, the East Rimouski River, the Grand Touradi River, the Little Touradi River and Little Rimouski River. The entire network is 2,090 kilometres (1,300 mi) streams.^[2] The basin also contains 864 lakes and 244 wetlands.^[2]

Geology

The entire river basin is part of the Appalachian. These are composed of sedimentary rock dating between 505 and 360 million years. The latter are aligned in parallel with the St. Lawrence River.^[2]

Toponymy

Rimouski appears in the act of concession of the Lordship of Rimouski, on April 24, 1968 ^{[ citation needed ]}. According to Mgr Louis-François Richer Laflèche, the name comes from the Mi'kmaq "animouski" and mean "mansion of dog". The leader Abenaki Jos. Laurent ("Sozap Lolo Kizitôgw") noted in 1888 noted that Rimouski came from the Abenaqui Alemoski and means "earth of the dog". As for the popular sense of land moose statement by Father Cyprien Tanguay, he would never have been accredited. The name may refer to the presence of seals, also called "sea dogs" or "sea lions" near the mouth of the river.^[4]

History

The history of the basin was marked by logging. The Price Brothers and Company had a virtual monopoly of this activity. The 6, a fire of Rimouski saw mill burned down 250 houses and put more 2000 people in the street.^[5]

Demographics

The population of the basin was 50306 person in 2007. 85% of the population lives in Rimouski, the only city in the basin.^[3]

Natural environment

47.2% of public forests are composed of stands of conifers and 23.5% of mixed forests. In private forests, 33.3% are composed of mixed forests and 23.5% are forests of deciduouss. Forests are quite young, only 2.6% are over 120 years. About 1% of forests are cut annually.^[6]

The basin includes 31 species of fish. The most common species are the brook trout (Salvelinus fontinalis), the chub (Semotilus atromaculatus), the northern pearl dace (Margariscus nachtriebi) and the red shiner belly (Phoxinus eos). The mouth of the river is a popular venue for white peach to Smelt rainbow sky (rainbow smelt). The Atlantic salmon (Salmo salar) frequents on 29 kilometres (18 mi) downstream to breed.^[7]

Four species of mammal live in the river: the Canadian beaver (Castor canadensis), the muskrat (Ondatra zibethicus), the river otter (Lontra canadensis) and the American mink (Neovison mink). We also found there 132 species of bird, 15 spécies of amphibian and six species of reptile.^[7]

Protection of land

The Rimouski basin includes two wildlife reserves (Rimouski and Duchénier), two controlled harvesting zones (Rivière-Rimouski and Bas-Saint-Laurent), an outfitting and a private hunting and fishing club.^[8]

As for protected areas, there are three containment areas of deer which cover 13.9% of the territory. It also meets two heronries, five habitats muskrat ^[8] and four exceptional forest ecosystems.^[6]
