| Description | Ecology monitored total dissolved gas (TDG) in the Spokane River during 2003, and compared these and other data to water quality standards. Natural processes generate TDG at Post Falls Dam. Upriver Dam generates TDG levels either below the 110% criterion or below upstream conditions. Long Lake Dam generates elevated TDG but Little Falls Dam contributes no additional TDG. Instead of a TMDL, FERC relicensing 401 certifications are adequate to address impairments. Spokane River TDG should be moved from Category 5 (TMDL required) to either Category 2 (waters of concern) or Category 4B (has a pollutant control plan). | ||||
