The Flood Early Warning System monitors rainfall, water levels and low water crossings in Austin 24 hours a day, 365 days a year. During a flood, we work closely with emergency managers for the most effective and timely community response.

Network of Gauges

  • 130 rain or creek level gauges
  • Flashing lights or automated barricades at 15 low water crossings
  • Gauge adjusted radar rainfall
  • Cameras at low water crossings
  • Predictive modeling and mapping.

Water Level Data

Even with this technology, every storm is different and sudden flooding can occur faster than we can respond. More than 10,000 buildings and 300 bridges in Austin are subject to flooding.
