The overnight storm that dumped rain across Texas sent a diluted wastewater overflow into the river, but caused few other problems in San Marcos. About 2.23 inches of rain were recorded at San Marcos Municipal Airport.
Stormwater entering the wastewater system triggered an overflow of an estimated 430,000 gallons into the San Marcos River Tuesday morning east of Interstate 35 near the main lift station, located at 502 River Road, said Jon Clack, a Public Services division assistant director.

The overflow consisted mostly of rainwater, further diluted by river flow, he said. Officials said they do not anticipate a negative environmental impact. The line is currently undergoing repairs after an overflow occurred at the same location in January.
Under the Texas Commission on Environmental Quality (TCEQ) rules, the City of San Marcos is required to notify area news media, local government officials and TCEQ about any accidental discharge of untreated wastewater of more than 100,000 gallons.
Both San Marcos Police and Fire Departments reported a quiet night. The Electric Utility experienced four minor brief outages, with all customers quickly restored.
Minor street flooding was reported at several low water crossings, including the Uhland Road bridge, Mckie Street at Willow Creek, Children’s Park road at Purgatory Creek, and inlet backups on Riverside Drive and Moon and University Drive.
Most were all open by mid-morning Tuesday. The Uhland Road low water crossing at the Blanco River remained closed Tuesday due to high water.
