The Rat River is a 220 km long left tributary of the Burntwood River in the Canadian province of Manitoba .

The Rat River has its origins in Walesiak Lake, which is about 280  m high in the central west of Manitoba. It initially flows through the smaller lakes Livingston Lake and Misseepastikwayakos Lake . It flows in a predominantly north-westerly direction. After 70 km the upper reaches of the Rat River flows into a lake-like widening at the northernmost point of the river. About 15 km further north is the South Bay Diversion Channel . Since 1976/77 a large part of the Churchill River has been diverted to the Rat River via this . Since then, an additional amount of water of around 760 m³ / s has flowed through the middle and lower reaches of the Rat River. On this are the lakes and river widenings Karsakuwigamak Lake , Pemichigamau Lake , Rat Lake , Misinagu Lake , Notigi Lake and Wapisu Lake . At Notigi , below Notigi Lake , the outflow of the Rat River is regulated by a weir. At this point, Provincial Road 391 crosses the river. The Rat River finally flows into Threepoint Lake , through which the Burntwood River flows. The natural catchment area of the Rat River covers 6140 km².
