Stream Gaging
Since 2000, the USGS in Iowa has been widely using hydroacoustic technology to make streamflow measurements.
As of 2004, almost every streamflow measurement is made with some form of hydroacoustic equipment.
This technology has been used on watersheds of all sizes from the Mississippi to drainages of only a few acres.
This has enabled the Iowa Water Science Center to collect discharge measurements more efficiently,
more accurately, and in more situations than was previously measured with conventional current meter methods.
In Iowa, the following methods are used to make streamflow measurements with hydroacoustics:
OSW Hydroacoustics | Indiana Hydroacoustics
| Stream Gaging | Lake
Mapping | Realtime Velocity
