Water Quality

The federal Clean Water Act requires DEQ to assess Oregon’s water quality and prepare a report every two years. The Integrated Report is a database report that combines reporting information for the Clean Water Act Section 305(b) assessment of all water bodies and the Section 303(d) list of water bodies that do not meet water quality standards where pollution reduction plans called Total Maximum Daily Loads are needed.
