Hydrologic Conditions

In Indiana, the Kankakee River has a total drainage area of 1,920 square miles. From its source in northern Indiana, the Kankakee River flows westward through several Indiana counties and into Illinois. It is a tributary of the Illinois River and is within the Mississippi Watershed. Major tributaries to the Kankakee River in Indiana include the Yellow River.

The Kankakee River lies in the Northern Moraine and Lake physiographic region of Indiana where the surficial geology consists of stratified sand and gravel. Historically, much of the Kankakee River in Indiana and Illinois meandered through an area called the Grand Marsh. By the early 20th century the entire main stem of the river in Indiana was extensively channelized to lessen flooding and drain swampland areas for agriculture.

Why Continuous Monitoring is Important

Over time, the quality of the Kankakee River and its tributaries (Yellow and Iroquois Rivers) has been altered by excess sedimentation from channelization and land use practices. A major concern to local residents and users of the Kankakee River is that sedimentation is limiting the recreational, ecological, and overall usefulness of the river.

The Kankakee River Basin Commission (KRBC) is a local Indiana agency charged with overseeing water resources within the basin including the Kankakee River and its tributaries. In 2016, the KRBC asked the USGS to install, operate, and maintain a super gage on the Kankakee River at Davis, IN. The gage will quantify concentrations and loads of sediment and nutrients being transported by the Kankakee River. This site, in particular, provides information about sediment and nutrient transport prior to the confluence with the Yellow River. Data provide information to understand effects of management practices within the watershed.
