Water Quality Program
This web site provides information about the U.S. Army Corps of Engineers program for water quality management in the Northwestern Division (Columbia Basin). This program includes monitoring of total dissolved gas, water temperature and turbidity; scheduling of reservoir operations for water quality; computer modeling; and performing studies designed to restore and enhance water quality in streams, rivers and lakes within the Columbia River Basin.
