On Saturday March 7, 2026, paddlers from all over Texas will participate in the longest single day river cleanup in the state – picking up trash along 60-90 miles of the San Marcos River. From just downstream of San Marcos down to Gonzales, canoeists, kayakers and rafters will be cleaning up the river and its banks.
In recent years, the Houston Canoe Club has cleaned River Section 2: from San Marcos River Retreat down to Sculls Crossing.
Stay tuned for more details as the date for the cleanup nears!
