The River Foundation supports clean-ups all year long including the mammoth Great Texas River Clean Up the first Saturday in March held in conjunction with the City of San Marcos. Canoe and diving clubs from all over Texas, civic groups, student organizations and the public participate in this massive clean up from the headwaters to the confluence of the Guadalupe, a stretch of 90 miles.
Keep San Marcos Beautiful is also conducting a month long clean up every Fall as well as monthly Hot Spot Clean Ups, the first Saturday of every month. The River Foundation is also able to help smaller groups with needed clean ups during the summer months when heavy recreational use leaves behind lots of trash along the banks.
