Plum Creek rises in Hays County and flows southeast to its confluence with the San Marcos River, covering roughly 288,240 acres primarily in Caldwell County, and includes portions of Hays and Travis Counties. Based on the 2014 Texas Integrated Report, Plum Creek is impaired due to bacteria and is also listed as having concerns for nutrient enrichment by nitrate and orthophosphorous. Through the TSSWCB-led Regional Watershed Coordination Steering Committee, Plum Creek was identified as a prime candidate for the development of a stakeholder driven watershed protection plan (WPP). Through a collaborative effort between TSSWCB, Texas Commission on Environmental Quality, Texas AgriLife Extension, and the US Environmental Protection Agency, the "Plum Creek Watershed Protection Plan" was developed in February 2008. The Guadalupe Blanco River Authority received a CWA Section 319(h) grant to hire a local watershed coordinator to provide support and facilitate the Plum Creek Watershed Partnership in implementation of management measures to improve water quality, develop proposals to acquire funding for implementation of management measures, manage and track implementation project as well as encourage adoption of best management practices.
