Author(s) Water Quality Program
Description The TMDL identifies water quality improvements needed to protect salmon and other aquatic life from elevated pH in the Lower White River watershed. Ecology’s study shows that nutrient pollution, especially soluble reactive phosphorus is the primary cause of the pH problem in the Lower White River. This TMDL comprises two documents. The first describes TMDL monitoring, modeling and analysis and includes wasteload allocations for municipal wastewater, municipal, construction, industrial stormwater, and sand and gravel permittees. The second document is an implementation plan that primarily describes best management practices for nonpoint sources.
