Hoosier Riverwatch is a program of the Indiana Department of Environmental Management, Office of Water Quality, Watershed Assessment and Planning Branch. The program began in 1996 to increase public awareness of water quality issues and concerns by training volunteers to monitor stream water quality.

The mission of Hoosier Riverwatch is:

To involve the citizens of Indiana in becoming active stewards of Indiana's water resources through watershed education, water monitoring, and clean-up activities. Hoosier Riverwatch is a State-sponsored water quality monitoring initiative.

We accomplish this mission through the following goals:

  • Educate citizens on watersheds and the relationship between land use and water quality.
  • Train citizens on the basic principles of water quality monitoring.
  • Promote opportunities for involvement in water quality issues.
  • Provide water quality information to individuals or groups working to protect water resources.
  • Support volunteer efforts by providing technical assistance, monitoring equipment, networking opportunities and educational materials.
