About the San Marcos River
Welcome to the San Marcos River, home of 7 different endangered/threatened species and crystal clear water that flows out of Spring Lake at 72 degrees year-round. The San Marcos River is unique because it begins in city limits at Spring Lake, where the water bubbles out of over 200 underground springs from one of the largest artesian aquifer systems in the world.
Research suggests that the greater San Marcos area has been home to humans as far as over 12,000 year ago due to this natural resource and it’s still the heart and soul of this City. The residents treasure this river and we want to make sure everyone who comes to use it do the same.
