The San Marcos River Rangers are volunteers trained as citizen scientists to conduct scientific data collection at 15 sites along the San Marcos River from Spring Lake to Prairie Lea. The oldest monitoring group in the state of Texas, the River Rangers have collected and tested water quality samples for 20 years, monitoring the health of the river and alerting city and county officials to potential problems. Their work has encouraged residents to take an active hands-on role in the preservation of the river, promoted environmental research and enhanced environmental problem solving by making their data accessible to the public.
