Flood Early Warning System

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.

The Flood Early Warning System includes:

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.

Sources of water data include:

City of Austin Creek Level Gauges
City of Austin Rain Gauges
LCRA Hydromet
USGS

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.
