The San Marcos River rises from the San Marcos Springs, the location of the Meadows Center for Water and the Environment (formerly Aquarena Springs), in San Marcos, Texas. The springs are home to several threatened or endangered species, including the Texas blind salamander, fountain darter, and Texas wild rice. The river is a popular recreational area, and is frequented for tubing, canoeing, swimming, and fishing.
