In 1998, the Washington State Legislature established the Washington State Watershed Management Act (codified under RCW 90.82) to address diminishing water availability and quality and the loss of critical habitat for fish and wildlife. Watershed planning under this Act was started in 1998 in the Chambers-Clover Creek Watershed (CCCW) Water Resources Inventory Area (WRIA 12) by a group of Initiating Governments, including Pierce County, the City of Tacoma, the Puyallup Tribe, and the Lakewood Water District. Upon completion of the Technical Assessment, and during preparation of the Watershed Management Plan, some members of the Initiating Governments and other project partners concluded that data gaps in the Technical Assessment would limit the usefulness of the plan. Planning Unit members and stakeholders have asked the USGS Washington Water Science Center to help design and conduct a study, including the construction of a numerical ground-water flow model, to address remaining data gaps and assist in the development of a long-term watershed management plan for the CCCW.
