// Strategic Significance

The Midnite Mine in Stevens County Washington is an abandoned uranium mine on the Spokane Indian Reservation leaving radioactive waste piles and contaminated water. The mine operated from 1954 to 1981 leaving uranium tailings that leach into Blue Creek and the Spokane River. The Spokane Tribe of Indians is a primary party in cleanup negotiations.

// Civilian Impact Assessment

Stevens County and the Spokane Tribe face ongoing radioactive contamination from uranium tailings in the Blue Creek watershed. The Spokane River downstream provides recreation and water supply.

// Evacuation & Shelter Guidance

Stevens County residents and Spokane Tribe members should follow EPA guidance on Blue Creek and Spokane River use near the mine site.
