It’s hard to prevent a natural disaster.
But, when it comes to flooding, U.S. Geological Survey (USGS) hydrologists do everything they can to predict one.
During a recent presentation in Decorah, USGS Hydrologist Jon Nania of Iowa City and National Weather Service (NWS) Service Hydrologist Mike Welvaert of La Crosse, WI discussed how a number of river gauges located in northeast Iowa can help predict potential flooding disasters.
Nania said basic hydrologic collection is a major part of the USGS Iowa Water Science Center program, based in Iowa City with field offices in Council Bluffs and Fort Dodge. Regionally, USGS hydrologists, hydrologic technicians and other science professionals collect data and conduct studies to help federal, state and local cooperating agencies solve practical water problems.
Stream gauges throughout northeast Iowa provide stage and flow information online via satellite link in real time.
