Development and Migration of a Critical Habitat and Its Affect on the Colorado River Protection Strategy at the Moab Uranium Mill Tailings Remedial Action Project Site
Moab Wash, an ephemeral stream, transects the site of a former uranium- ore processing facility and existing mill tailings pile before entering the Colorado River near Moab, Utah, USA. Dissolved ammonia in ground water emanating from the tailings pile discharges to backwater channels of the river. The channel morphology and therefore presence of critical habitat is dependent on the flow of the wash and the river. Since 2001, the habitat area has changed such that DOE has adjusted its river protection strategy from freshwater diversion into backwater channels to include freshwater injection via wells into ground water.
