San Marcos is a city built around a spring-fed river, and the aquifer that feeds that river is at Stage 4.
The San Marcos River rises from more than 200 artesian springs at Spring Lake, runs at a constant 72 degrees year-round, and flows straight through the Texas State University campus at Sewell Park. It is one of the largest spring-fed rivers in Texas. Texas State has more than 38,000 students. In San Marcos, the water table is not an abstraction, it is the river people swim in.
The City of San Marcos is under Stage 3 drought restrictions as of September 2026. Hose-end and automatic sprinklers are limited to one day every other week, before 10am or after 8pm. Drip irrigation and soaker hoses get one day a week in the same windows. The city draws from three supplies: the Edwards Aquifer, Canyon Lake through the Guadalupe-Blanco River Authority, and the Alliance Water regional partnership with Kyle and Buda. For anyone pumping directly from the Edwards Aquifer under a permit, the Edwards Aquifer Authority\u2019s San Antonio Pool is at Stage 4, which prohibits outdoor irrigation outright. Stage 5 is the most severe tier on that scale. The aquifer under Stage 4 restrictions is the same aquifer that feeds the river above. Every gallon not sprayed on a lawn is a gallon closer to staying in it.
