The Indiana Water Monitoring Inventory is a portal for locating water monitoring information in the state of Indiana. Many government agencies and organizations monitor Indiana's waters, and this site provides a one-stop site where you can locate monitoring sites, determine what data have been collected, and contact the data holders or their web site for more information. The actual monitoring data is not stored here -- only detailed information on the location of the monitoring site and what is being monitored or was monitored in the past.
