Site description Beaver Lake is the name for a wide part of the Mackenzie River where the river meets the western end of Great Slave Lake. Fort Providence, Northwest Territories is situated 20 kilometres downstream. Most of the land surrounding the lake is low-lying and underlain by shales and limestones. Big Island sits at the mouth of the Mackenzie River and so separates Beaver Lake (the river) into two channels, North and South. The north shores of these channels contain large areas of sedge-grass marshes, whereas narrower marshes line the south shores. Islands of the North Channel are generally low and marshy, but the islands of the South Channel are higher and often hold small spruce-poplar forests.
