CLEAN AND ABUNDANT WATER FOR HUMAN COMMUNITIES Protect and Enhance Watersheds and Ecosystems that Provide Water Quality and Supply Benefits
The Mattole Integrated Water Management Program integrates basin-wide efforts to meet water supply, water quality and salmonid habitat goals for the coastal Mattole River watershed. The Program will yield increased water supply in drought-prone areas, augmented summertime streamflows in critical salmon-bearing reaches, sediment reduction to meet TMDL and NCRWQCB Basin Plan goals, and habitat improvements. A suit of effectiveness monitoring components will determine project performance and future management measures. By implementing these projects through an existing and robust watershed partnership, the project will address multiple management goals for habitat and water supply.
