A river in the north Okanagan, the Shuswap River has its headwaters in the
Monashee Mountains. It flows first into Sugar Lake. It drains Sugar Lake at the south end, makes a 180 degree turn and feeds
Mabel Lake from the south. It flows westward from Mabel Lake until it reaches
Enderby, then north into
Mara Lake. Mara Lake is joined to
Shuswap Lake.
