Meadows Center is a managed spring dive site in San Marcos.
Access is managed by the Meadows Center through authorization, scheduling, and supervised programs rather than walk-up diving.
Meadows Center for Water and Environment, San Marcos, Texas is the managed dive site at Spring Lake, a spring-fed freshwater system at the headwaters of the San Marcos River. It is best known for crystal-clear water, stable temperatures, and a conservation-first dive program rather than casual open access. Divers need advance authorization, and many visits are tied to training or guided work inside controlled zones. The draw is a rare mix of clear water, protected habitat, and close-up freshwater ecology.
