Rice Lake, IL Habitat Rehabilitation and Enhancement Project

Rice Lake is a 6,800 acre backwater complex located 24 miles southwest of Peoria, Illinois, in Fulton County on the right descending bank of the Illinois Waterway. The project lands are state owned and are managed by the Illinois Department of Natural Resources as a fish and wildlife area. Increased flood and sedimentation levels have resulted in degradation of what has historically acted as excellent mid-migration waterfowl and aquatic habitat. The lack of reliable and flexible water management capability over half of the project area severely limits its effectiveness in providing feeding and resting habitat for the 2.7 million annual waterfowl use days. Habitat degradation also has negatively affected the other migratory and resident species using the facility. The project goals are to enhance and restore wetland, and aquatic habitat. The objectives identified to meet these goals are:
1. Increase the areal coverage of annual emergent and moist soil vegetation in Big and Goose Lakes during the summer growing season;
2. Decrease summer water levels to below EL 440 in Big Lake, Goose Lake, and Rice Lake to promote vegetation growth during the summer growing season;
3. Increase connectivity between Big and Goose Lakes and the Illinois River during summer drawdowns to reduce fish mortality and avian botulism; and
4. Increase areal coverage of floodplain forest and wetland vegetation on Duck Island agricultural fields to provide scarce habitat for wildlife.
This project will provide increase water management flexibility and the capability to optimize the quality of quantity of aquatic, wetland, and floodplain habitat with the refuge area.
