Abstract:

Peoria Lake, located on the Illinois River in Illinois, is the deepest lake in the river valley. Since 1903, the lake has experienced approximately a 31% loss of original storage capacity due to sedimentation. In recent years, the sedimentation rate has increased to about 1. 20 inches per year, resulting in the deterioration of the water quality and recreational value of the lake. The primary sources of the sediment are increased sediment loads in the Illinois River and erosion from surrounding bluff areas and agricultural lands.
