Upper San Marcos River: Watershed Protection Plan
The Upper San Marcos River is included on the 2010 303(d) List due to elevated concentrations of total dissolved solids (TDS). There are significant interactions between the San Marcos River and the Edwards Aquifer, and both are experiencing pressures related to development and land use changes.
This project will develop a WPP for the San Marcos River to reduce TDS in the river, and also proactively address concerns related to bacteria, nutrients and sediment in the river and in Spring Lake.
