Spokane
River Water Quality Improvement ProjectsThe Spokane River is one of the most prominent features in Spokane, Washington. Protecting the river is of great economic importance to the people of Spokane and the surrounding area as its recreational and aesthetic values encourage tourism and create a very desirable place to live. The river also has six dams generating hydroelectric power.
The Spokane River flows 111 miles from Lake Coeur d’Alene in Idaho to its confluence with the Columbia River. Major tributaries include the Little Spokane River and Hangman (Latah) Creek. This watershed is made up of forest, agriculture, urban and range lands. Agricultural lands lie primarily in the Lower Spokane, Little Spokane, and Hangman Creek watersheds. The urban land use occurs mainly in the Middle Spokane watershed, due primarily to the location of the city of Spokane.
Below the river lies the Spokane Valley – Rathdrum Prairie Aquifer, the sole source of drinking water for over 400,000 people in the region. In some places the aquifer discharges into the Spokane River and in other locations the river discharges into the aquifer. Check out the Spokane Aquifer Joint Board’s webpage to learn more about the aquifer.
