The Fixed Station Monitoring Program

IDEM’s Fixed Station Monitoring Program provides monthly data for water quality trend analysis and many existing and prospective users of surface water information in Indiana. Water quality data are collected monthly from 163 sites on various rivers and streams. Although the number and location of some of these stations have changed over time, a number of the stations have been continuously monitored since 1957. The program was developed to determine chemical, physical, and bacteriological characteristics of Indiana water under changing conditions. Because samples are collected throughout the year, it provides critical information for understanding seasonal variation.
