Tracking water quality and quantity data over time establishes a foundation for watershed management. This type of data can be used by various groups to assess the health of the environment as well as identify potential impacts and priority areas for restoration. The SJRBC began a baseline water sampling program in 2014 with the goal of characterizing waterbodies that lacked historic data. A map of all the sampling sites and the data collected through that effort is available below. In 2021, the SJRBC initiated a long-term biological monitoring program to evaluate water quality trends at 12 sites throughout the Indiana and Michigan portions of the basin. The results of this program are available below.
