Site description MClintock Bay and the Lewes River Marsh are located about 30 kilometres southeast of Whitehorse, in the Yukon Territory. The shallow MClintock Bay is at the north end of Marsh Lake; here the outflow of the Yukon River is adjacent to the inflowing MClintock River, which has a rich delta, mudflats and beds of submergent aquatic vegetation, including pondweeds. Three kilometres downstream along the Yukon River is the Lewes River Marsh, which consists of side channels, shallows, marshes and mudflats on both sides of the main channel.
