Water Quality Improvement Projects
Water Cleanup Plans:
Listed by County and Water Resource Inventory Area (WRIA)

Water cleanup plans will result in cleaner lakes, streams, rivers, and bays. Clean water is vital for our quality of life – for both economic development and a healthy environment. Water quality improvement projects, including total maximum daily loads (TMDLs) are one way to return our water bodies to a healthy condition.

TMDLs describe the type, amount and sources of water pollution in a particular water body; they analyze how much the pollution needs to be reduced or eliminated to meet water quality standards; and they provide targets and strategies to control the pollution.
