The Churchill River (alternative name: Rivière Churchill ) is a 1,609 km long river in the Canadian provinces of Alberta , Saskatchewan and Manitoba .
Since 1977, 60% of the water from the Churchill River has been diverted to the Nelson River - about 760 m³ / s. At the mouth of the Churchill River, only about 510 m³ / s flow on average today.
The river has its origin in Churchill Lake in western Saskatchewan. From there it flows eastward through a series of lakes such as Lac Île-à-la-Crosse , Pinehouse Lake , Highrock Lake , Granville Lake , Southern Indian Lake . It flows into Button Bay in Hudson Bay near Churchill .
However, its catchment area extends far into Alberta via the Beaver River . Other important tributaries are the Rapid River and the Reindeer River .
The amount of water above Red Head Rapids ( ⊙ ) fluctuates between 123 m³ / s (January) and 887 m³ / s (May 2000).
Hydropower plants
The Island Falls hydropower plant, built between 1927 and 1931, now has seven turbines with a total output of 105 MW and is operated by SaskPower . It is east of Lac la Ronge near the Sandy Bay settlement .
