San Marcos River

The San Marcos River bursts forth from the Edwards Aquifer through 200 spring openings at the bottom of Spring Lake in the heart of San Marcos, Texas. The river provides a refreshing playground for swimming, canoeing, and tubing. The San Marcos River winds through over 130 acres of parkland. The upper 3.8 miles of the headwaters provides habitat to eight endangered and threatened aquatic species, including the San Marcos Fountain Darter, Texas Blind Salamander, the San Marcos Salamander, the San Marcos Gambusia and Texas Wild Rice. Archaeologists have discovered artifacts that indicate that the area around the Springs is one of the oldest continuously inhabited places in North America by human beings, dating back more than 12,000 years.
