Rock Island District
Description
Sedimentation has destroyed much of the fish and wildlife habitat value of Peoria Lake. The lake has lost approximately 68% of its original volume and the average depth has been reduced from 8.1 to 2.6 feet since 1903. The shallow depths from silt accumulation promote re-suspension of sediments, resulting in elevated turbidity levels. The soft lake bottom is not receptive to the rooting and survival of aquatic plants for waterfowl consumption and aquatic use. Sedimentation in the East River channel has also reduced the aquatic habitat of the lake.
