San Antonio River Authority Work to Safely Relocate Native Fish Species during River Walk Draining
WHAT: The San Antonio River Authority (River Authority) will conduct operations and maintenance activities as a part of the City of San Antonio’s (COSA) draining of portions of the San Antonio River along the River Walk. The section the River Authority will focus on the Museum Reach from Pearl to Lexington Ave. River Authority staff will leverage the opportunity of lower water to perform preventative maintenance and improve the river’s habitat function by planting aquatic native plants. In addition to operations and maintenance activities, crews from the River Authority’s Environmental Sciences Department will be serving as the lead biologists throughout the entire River Walk area during the draining. The River Authority’s scientific staff will be working to save and relocate native aquatic species to other appropriate parts of the river while removing any non-native invasive species. They will also be on the lookout for non-native invasive fish species like the Plecostomus (suckermouth catfish) and tilapia, and the non-native invasive Apple Snail, which was discovered in the River Walk in October 2019. The operations and maintenance work, as well as the biological efforts, are all part of the River Authority’s commitment to safe, clean, enjoyable creeks and rivers.
WHEN: Tuesday, January 25, 2022 @ 10:00 a.m.
