The river flows through the cities of San Marcos and Luling before merging with the Guadalupe River near Gonzales. The hydrology of the river is affected by upstream dams and tributaries, such as the Plum Creek and the Blanco River. Seasonal trends in the flow of the river are influenced by precipitation and groundwater levels, with typically higher flows during the spring and lower flows in the summer. Interestingly, the San Marcos River is home to a unique ecosystem of plants and animals, including several endangered species, and is a popular recreational spot for tubing and swimming.
