Site description Lake St. Martin is located between Lake Manitoba and Lake Winnipeg. Water from Lake Manitoba flows to Lake St. Martin via the Fairford River, and Lake St. Martin flows into Lake Winnipeg through the Dauphin River. Not much is known about the vegetation on the islands within the lake, but they are low-lying and likely far enough offshore to provide protection from predators. The surrounding shoreline of Lake St. Martin is generally flat and often marshy.
