The San Antonio River will be drained for a week early in 2022. City officials announced on Tuesday that the river will be drained between Sunday, January 23rd, and Sunday, January 30th, for maintenance and cleanup purposes. The main part of the River Walk will be drained completely, and the main channel between East Josephine Street and East Nueva Street will be partially drained. Go Rio Cruises won't be operating in the downtown or Museum Reach areas for that week.
