Source monitoring and evaluation of sediment inputs for Peoria Lake.


Publication Date


This report summarizes the results of a two-year study on the determination of the input of sediment to Peoria Lake from its local tributaries. Ten local tributaries were monitored to determine the flow of sediment and water. Long- term average deposition of coarse material at the mouths of these tributaries was estimated as bed load based on the progression of the deltas at the base of the tributaries. Sediment inflow to Peoria Lake from the Illinois River was determined based on the estimated sediment load at the Henry gaging station. Water year 1989 (WY89) was essentially a dry year and WY90 was average. The present analyses have shown that about 1.2 million tons of sediment flowed into Peoria Lake in WY89 and about 2.7 million [...]
