The Metchin River , also Maikan-nipiu-shipiss , is an approximately 130 km long left tributary of the Churchill River in the central southeast of the Labrador Peninsula in the Canadian province of Newfoundland and Labrador . The river is also sometimes referred to as the East Metchin River or East Metchim River .

River course

The Metchin River forms the outflow of the 500  m high Disappointment Lake (Kaishikashkau) . It initially flows 50 km in a predominantly westerly direction. Hope Lake and Kaishikashkasht are located on the upper reaches . At river kilometer 84 the Metchin River leaves a heavily branched lake in a southerly direction. This lake has another outflow to the west that flows to Smallwood Reservoir . The Metchin River flows southeast to a larger lake about 20 km and then turns to the southwest. The Metchin River then flows through the two lakes Maikan-natuashu and Maikan-nipiss . The Metchin River flows in a south-southwest direction for its last 35 km. The Trans-Labrador Highway crosses the river at river kilometer 21 . There is a discharge level here. About 1.2 km downstream, the Wilson River flows into the Metchin River from the east. Another 1.7 km downstream the Tshinusheu-shipiss flows into the river from the right. The Metchin River finally flows into the Churchill River 48 km east-southeast of the Churchill Falls hydroelectric power station .

Hydrology

The Metchin River drains an area of ​​about 3400 km². At the gauge 20.5 km above the mouth, at the point where the Trans-Labrador Highway crosses the river, the mean discharge is 21.5 m³ / s. In May, the Metchin River usually carries the largest amount of water with an average of 81.9 m³ / s.

Wildlife

In the river system of the Metchin River probably following types of fish: three-spined and nine-spined stickleback , brook trout , pike and Arctic Norway and the Redhorse TYPES Catostomus Catostomus (longnose sucker) and Catostomus commersonii (white sucker). The Muskrat Falls on the Churchill River prevent fish migration of anadromous salmon in the Metchin River. Beavers , muskrats , American water shrews and North American river otters use the river as a habitat. On the banks of the water and in the wetlands, you can find Wilsonbe cassins , greater yellow thighs , belt fishermen , Canada goose , middleman and Odin's chickens .
