Nine Mile Falls is anunincorporated community in Spokane County, Washington and Stevens County, Washington, United States. The community straddles theSpokane River 9 miles (14 km) from downtownSpokane, at the location of a former falls that has been the site ofNine Mile Dam since 1908.
Nine Mile Falls has a post office with ZIP code 99026.[2]
As the name suggests, the community is located nine miles northwest of Downtown Spokane along the Spokane River. That naming convention can also be seen in the nearby community of Seven Mile and the Spokane neighborhood ofFive Mile Prairie. Unlike those two, however, Nine Mile Falls is not part of the contiguous built up urban and suburban area surrounding Spokane. Suburban sprawl comes within two miles of the community, but does not directly abut it, making Nine Mile Falls anexurb of Spokane.
The community is located alongWashington State Route 291,[3] known in the area as Nine Mile Road, which follows the route of the river. Traveling from Spokane, visitors first encounter the eastern portion of the community. The western portion of the community across the river is accessed by turning off Nine Mile Road onto Charles Road, which crosses the river a few hundred feet downstream of the dam. The post office and most of the services are located on the eastern side of the community. The west side is home to a park, fire station, restaurant and elementary school. Sontag Park on the west side of the community is the western end of theSpokane River Centennial Trail, which provides access toRiverside State Park which stretches along the river for miles upstream of the community.[4]
TheLittle Spokane River flows into the Spokane River just north of Nine Mile Falls. From that point and extending downstream the Spokane River serves as the border between Spokane and Stevens Counties. Nine Mile Dam impounds the Nine Mile Reservoir. Long Lake, also known as Lake Spokane, the reservoir behindLong Lake Dam, begins almost immediately downstream from Nine Mile Dam.[3]
Geologically, the community is dominated by theColumbia River Basalt Group, alluvium laid down by glacial outburstMissoula floods, and the erosive action of the Spokane and Little Spokane Rivers.[5] The Spokane River turns from a northwestern direction to a western path just downstream of Nine Mile Falls, as it navigates around the southern foothills of theSelkirk Mountains.[5] The first of those foothills are visible in the photo at the top of the article. The river cut a thin and steep roughly 200-foot-deep valley through the surrounding plateau.[3] Downstream of the site of the falls the valley widens and becomes shallower. Areas that have not been cleared for development or farming are covered inponderosa pine forest.[6]
Nine Mile Falls is located in theNine Mile Falls School District. Nine Mile Falls Elementary School is located within the community, but the middle and high schools are located in nearbySuncrest.

TheSpokane people inhabited the area for thousands of years prior to European settlement.[7] The rivers supported salmon runs that provided bountiful food for the area's inhabitants, though the runs were killed off when Long Lake Dam was built in 1915 without a fish ladder[8] There are ancient rock paintings located along the Little Spokane River just upstream from its confluence with the Spokane River.
Europeans have had a constant presence in the Nine Mile area since theSpokane House was established at the confluence of the two rivers in 1810.
The community now known as Nine Mile Falls was first developed in 1908 when Spokane industrialist Jay P. Graves built the Nine Mile Dam to provide electricity for his Spokane & Montrose motorized streetcar system.[9] The electricity generated at the dam helped spur the expansion of Spokane's streetcar andinterurban railway systems,[9] and in turn helped spur the growth of the greater Spokane area. A village was built at the site of Nine Mile Falls to provide housing for dam workers and their families.[10] The hydro plant and adjoining village were placed on theNational Register of Historic Places in 1990. The historic areas of the hydroelectric complex are jointly managed by Avista Utilities, which operates the dam and power generation, and Riverside State Park.[11]
