Iowa Flood Information System
The Iowa Flood Center at the University of Iowa has developed a Google Maps based flood information system to provide real-time flood conditions for the state.
The map includes an overlay displaying the Iowa river network. It also displays real-time water level and gauge heights with warning levels and rainfall conditions. You can filter the map to show current rainfall totals or rainfall totals for today or for the week.
Flood warning levels are shown indicating areas with 'Major Flood', 'Moderate Flood', 'Flood Stage' and 'Action Stage' warnings.
