The San Marcos River Rangers are volunteers trained as citizen scientists to conduct scientific data collection at 30 sites along the San Marcos and Blanco rivers.
As the oldest and one of the largest monitoring groups in the state, the River Rangers have collected and tested water quality samples along the San Marcos and Blanco rivers for 28 years, monitoring the health of the river and alerting city and county officials to potential problems. Over 50 monitors go out monthly to collect samples and further our understanding of the river’s cycles.
SMRF works with numerous groups and has provided local teachers with grant money to start their own water quality testing programs for middle and high school students.The River Rangers have trained over a thousand monitors from across the state to become state certified water quality monitors, accounting for more than a third of all monitors in the state.
