The Ashuanipi River is an approximately 345 km long tributary of the Smallwood Reservoir in the center of the Labrador Peninsula . It forms the headwaters of the Churchill River .
River course
The Ashuanipi River forms the outlet of Ashuanipi Lake , which is 529 m high . It flows just 40 miles north to the Menihek Lakes . It flows through this over a length of 100 km. A major tributary of the Menihek Lakes is the McPhadyen River coming from the west . At the outflow of the Menihek Lakes there is a dam with a hydroelectric power station. This has an installed capacity of 18.7 MW and uses a maximum fall height of 12 m. The Ashuanipi River then flows in an S-bend through a lake system consisting of Marble Lake , Astray Lake and Petitsikapau Lake . Eventually it turns southeast for the last 100 km and flows into the northwest shore of Smallwood Reservoir. The river has lake-like broadening along almost its entire length. The Trans-Labrador Highway ( Route 500 ) from Labrador City to Happy Valley-Goose Bay crosses the river 6 km below Ashuanipi Lake.
Hydrology
The Ashuanipi River drains an area of 25,928 km². The mean discharge below the Menihek Lakes is 394 m³ / s. The highest monthly discharge usually occurs during the snowmelt in June with an average of 1020 m³ / s.
