Upper Mississippi River System Environmental Management Program Definite Project Report with Integrated Environmental Assessment (R-6F). Peoria Lake Enhancement, Peoria Pool, Illinois Waterway, River Miles 178.5 to 181, State of Illinois
Abstract
Assessment of the existing resources available in the Upper Peoria Lake environs resulted in the following observations: permanent year-round aquatic and side channel habitat is limited throughout the project area; emergent wetland habitat is minimally available at this location; waterfowl food production varies annually and in general is limited; and high turbidity values and suspended solids concentrations define Peoria Lakes's water quality status. Project goals that would address these conditions were developed for Upper Peoria Lake. The project goals are the enhancement of aquatic and wetland habitats. The following objectives were determined to support the stated goals: (1) increase reliable food production and resting area for waterfowl; (2) increase diversity and areal extent of submergent and emergent vegetation for waterfowl and; (3) provide flowing side channel habitat. Multiple project sites, construction alternatives, and design configurations have been considered for the purpose of realizing the stated project goals and objectives. Thorough analysis of all options resulted in the recommendation of the following design features: construction of a forested wetland management area; creation of a barrier island; and establishment of flowing side channel and rock substrate habitat. Keywords: Illinois waterway.
