In partnership with the Iowa Department of Natural Resources, the ISU Limnology Lab monitors the water quality of over 130 publicly significant lakes in the state of Iowa. This vast data set has been collected for more than 20 years and is used to assess the health of Iowa's lakes and inform management and restoration efforts. To learn more about the program, visit the DNR website.
DATA AVAILABILITY: The data can be freely accessed through the DNR's AQuIA database: Select "21IOWA-Iowa DNR Surface Water Monitoring Data" Then "Results - By Project/Task" Then "AMBLAKE - ISU"
Des Moines River Water Quality Network
The Des Moines River Water Quality Network (DMRWQN) is a surface water quality monitoring project, conducted by investigators in Iowa State University's departments of Ecology, Evolution and Organismal Biology and Civil, Construction and Environmental Engineering under contract with the Rock Island District of the U.S. Army Corps of Engineers. This intensive data set, which involves year round sampling, has been collected for 40+ years at these sampling locations.
The Army Corps of Engineers is working to create a public data repository. In the meantime, contact the Rock Island District to request access to the river and reservoir data.
