Today, the river and its watershed are managed by the Nisqually Indian Tribe, Nisqually National Wildlife Refuge, and local governments. The hydrology of the river is influenced by seasonal snowmelt and precipitation. There are two major reservoirs on the river, Alder Dam and LaGrande Dam, which are used for hydroelectric power generation and water supply. The river is also used for recreational activities such as fishing, kayaking, and rafting. Agricultural uses include pastureland and crops such as berries and vegetables. Efforts to restore and protect the river and its habitats are ongoing.
