Upper Peoria Lake is a section of the Illinois River primarily between Peoria County and Woodford County, Illinois, United States. The lake runs from South Rome to Peoria Heights, with Spring Bay and the Detweiller Marina area of Peoria near the middle. Just north of Peoria Heights, it empties through a narrow part of the Illinois River into the smaller Peoria Lake, sometimes called Lower Peoria Lake, at approximately river mile 166.5.[1]
Geology
[edit]The Upper Peoria Lake originated during the Woodfordian substage of the Wisconsin glaciation.[1][2] It is part of the Bloomington moraine.[2] Upper Peoria Lake is a remnant of old Glacial Lake Illinois, which formed behind the moraine.[2]
Due to the flat stream bed, the water moves slowly, allowing sediment to settle at the bottom.[2]
Restoration
[edit]Since 1903, the lake has lost approximately 68% of its original volume and the average depth has been reduced from 8.1 ft (2.5 m) to 2.6 ft (0.79 m).[3] Sedimentation and the soft bottom of the lake are not conducive for aquatic plants, which attract waterfowl.[3]
In July 1990, the Peoria Lake Habitat Rehabilitation and Enhancement Project, a joint project between the U.S. Army Corps of Engineers, U.S. Fish and Wildlife Service, and Illinois Department of Natural Resources, worked on the northernmost end of the Upper Peoria Lake.[3] This project achieved:
- Constructed the Barrier and Overburden Islands and dredged approximately 229,366.457 m3 (8,100,000.0 cu ft) of sediment
- Excavated a channel in the East River to remove a silt plug
- Constructed a rock closure to reduce sediment from the northern boundary with Goose Lake
- Constructed approximately 18,585 ft (5,665 m) of low level levees, 3 water control structures, and a pump station
- Planted select vegetation to enhance the wetland habitat
Fauna
[edit]Pollution has been a significant factor in decreasing levels of wildlife.[4][5][6]
