Cochrane River (Canada)
The Cochrane River is a river in Manitoba and Saskatchewan, Canada. Located in the boreal forest of the Canadian Shield, it flows from Wellbelove Bay on the northern end of Wollaston Lake in north-eastern Saskatchewan to the north-east end of Reindeer Lake in Manitoba. The river has a drainage basin of and is part of the Churchill River drainage basin.
Drainage system (geomorphology)
A deranged drainage system is a drainage system in drainage basins where there is no coherent pattern to the rivers and lakes. It happens in areas where there has been much geological disruption. The classic example is the Canadian Shield. During the last ice age, the topsoil was scraped off, leaving mostly bare rock. The melting of the glaciers left land with many irregularities of elevation and a great deal of water to collect in the low points, explaining the large number of lakes which are found in Canada. The drainage basins are young and are still sorting themselves out. Eventually the system will stabilize.
