Sediment and Nutrient Monitoring at Selected Watersheds within the Kaskaskia River Watershed for Evaluating the Effectiveness of the Conservation Reserve Enhancement Program (CREP)

The Conservation Reserve Enhancement Program (CREP) was initiated as a joint federal/state program with the goal of improving water quality and wildlife habitat in the Illinois and Kaskaskia River basins. Based on numerous research and long-term data in the Illinois River basin, the two main causes of water quality and habitat degradations in major river corridors were known to be related to sedimentation and nutrient loads.

Quarterly Monitoring of the Vermilion River Near Pontiac Illinois
