Vision Statement

A healthy watershed that supports a clean, clear, and flowing San Marcos River for the future as it was in the past.

The Initiative

In 2010, the Upper San Marcos River was cited on Texas Commission on Environmental Quality’s 303(d) list of impaired waterways, for exceeding total dissolved solids (TDS) water quality standards. The River is currently in compliance with the Clean Water Act Standards, but several pollutants have been identified as a concern.

The San Marcos Watershed Initiative (SMWI) began in 2012 as a multi-year process of research and information gathering with the end goal of implementing a community approved and federally accepted Watershed Protection Plan for the Upper San Marcos River. Read more.
