Water Resources and Water Quality

This page provides information about water resource planning and water quality for local governments in Washington State, including examples of local programs, water quality reports, and recommended resources.


The state Department of Ecology (DOE) works closely with Washington communities and their citizens to provide effective water management. In the past, Washington has enjoyed an abundance of water, but water availability is no longer a state luxury. Washington is committed to meeting current water needs and ensuring future water availability for people, fish and the natural environment. See DOE's water resources program at Water Resources, Washington State Department of Ecology. It includes information on the Office of the Columbia River, conservancy boards, dam safety, instream flow, measuring water use, rainwater collection, water rights, water market, water resource program activities, watershed management, wells, and the Yakima Basin.

  • Yakima Basin Surface Water Initiatives, Yakima County Surface Water Management Division - Participates in planning processes that effect water quality, water quantity and flow management, groundwater, and riverine habitats. The division supplies technical information to these planning processes and also assists the Yakima County Commissioners who

Clean Water, Water Quality

The objective of the Federal Water Pollution Control Act, commonly referred to as the Clean Water Act (CWA), is to restore and maintain the chemical, physical, and biological integrity of the nation's waters by preventing point and nonpoint pollution sources, providing assistance to publicly owned treatment works for the improvement of wastewater treatment, and maintaining the integrity of wetlands. See Clean Water Act, U.S. Environmental Protection Agency. This version is on EPA's Agriculture website and provides detailed subheadings and related topics.

  • Water Quality Program, Washington State Department of Ecology - The goals of the state's water quality program are to prevent and clean up water pollution and to help communities make sustainable choices that reduce and prevent water quality problems.
  • Puget Sound Partnership - The Puget Sound Partnership is a community effort of citizens, governments, tribes, scientists and businesses working together to restore and protect Puget Sound.
  • Polluted Runoff: Nonpoint Source Pollution, U.S. Environmental Protection Agency - Provides links to EPA water pollution topics
  • Regulatory Information Topics Water, U.S Environmental Protection Agency - EPA enforces federal clean water and safe drinking water laws, provides support for municipal wastewater treatment plants, and takes part in pollution prevention efforts aimed at protecting watersheds and sources of drinking water.

Clean Water Programs

Many of these programs include public education and outreach.

  • Clark County Clean Water Program The program's primary activities include stormwater capital improvements, water quality monitoring, public education and outreach, regulations and enforcement, and stormwater maintenance. As the county's population continues to increase, Water Resources is committed to keeping our waterways clean for people, fish, and wildlife.
  • King County Stormwater Services and Information
  • Olympia Storm and Surface Water Education and Action
  • Skagit County Public Works Clean Water Program - The goal of the Clean Water Program is to address and deal with non-point pollution and to enhance Skagit County's water quality. It consists of a myriad of activities directed at educating the public, controlling storm water pollution, developing water quality monitoring plans, and restoring habitats among many other goals.
  • Vancouver Water Resources Protection Program - Resources and materials related to the city's water resources protection ordinance to help protect critical aquifers

Animal Waste, Agricultural Practices

  • Dairy Nutrient Management, Washington State Department of Agriculture - A water quality program administered by Washington State Department of Agriculture under Chapter RCW 90.64, Dairy Nutrient Management Act. Elements of the program are managed in conformance with a Memorandum of Understanding with the Washington State Department of Ecology. Ecology is the delegated agency in Washington for the Federal Clean Water Act.
  • Washington Home *A* Syst, Washington State University, Water Quality Management Team - Home and Farm*A*Syst programs provide voluntary and confidential water quality/environmental risk assessments you can use to evaluate your home and/or farm property for pollution and health risks. Although its emphasis is on protecting drinking water resources, following the "best management practices," the program also helps protect the entire watershed's water quality.
  • Animal Waste Management, Washington State Department of Ecology
  • Animal Wastes, MRSC - Provides information on the relationship of pet waste to water pollution and provides sample local ordinances regulating pet waste

Boating and Marinas

The state Department of Ecology, Washington Parks, and Washington Sea Grant offer programs for pollution prevention education and funding for boat maintenance and repair, oil spills, sewage disposal, and other water pollution topics associated with boating and marinas.

Lake and Beach Management Districts

In 2008 the lake management district provisions were amended to include the formation of beach management districts (Laws of 2008, ch. 301). The purpose of the lake and beach district legislation is to establish a governmental mechanism by which property owners can embark on a program of lake or beach improvement and maintenance.

Shellfish Protection Districts

These provisions encourage, and in some cases, require counties to establish shellfish protection districts and programs to curb the loss of productive shellfish beds caused by nonpoint sources of pollution, such as stormwater runoff, failing on-site sewage systems, and runoff from farm animal wastes.

Water Quality Reports

State and federal drinking water rules require Group A community water systems – those which serve 15 or more connections or 25 or more people – to produce and distribute a Consumer Confidence Report (CCR) to customers and the state Department of Health before July 1 each year.

For more information, including the current year's state certification form, tips for preparing a user-friendly report, and a checklist for CCR compliance, see the state Department of Health webpage Preparing a Consumer Confidence Report (CCR).

Below are examples of various formats used by various jurisdictions to provide the required water quality reports to their customers.
