Welcome to Iowa's STORET Database

The ambient water quality program is a diverse program responsible for the collection, analysis and dissemination of information on Iowa’s rivers, lakes, groundwater and wetlands. Physical, chemical, biological and habitat data are administered as part of this program. To handle this complex data set, the Iowa Department of Natural Resources (IDNR) is using the Environmental Protection Agency (EPA) database called STORET (STOrage and RETrieval). Iowa's STORET  database runs on a Oracle^TM database platform and is managed by the water monitoring section of the Iowa Geological Survey Bureau. Ultimately, the water monitoring section envisions Iowa STORET as a “one-stop shopping” location for all the state’s water monitoring data. For information on current and future monitoring data in STORET click here.
