The Nisqually River’s source is the Nisqually Glacier on Mount Rainier. The river gathers water from other tributary streams and slows and widens as it reaches the delta. The delta has been formed by the river carrying and dropping sediment as it slows to meet the Puget Sound. The Nisqually River is a critical habitat for endangered and threatened salmon runs. The River Overlook provides a great view of the river, including an area influenced by salt water from the Puget Sound. During fishing season, Nisqually Tribal fishing floats are visible in the water.
