Upper Mississippi River System - Environmental Management Program Definite Project Report (R-4) with Integrated Environmental Assessment. Andalusia Refuge Rehabilitation and Enhancement. Pool 16, Upper Mississippi River, Rock Island County, Illinois. Technical Appendices
Abstract
The Andalusia Refuge area is located within the Upper Mississippi Wildlife and Fish Refuge between river miles 462 and 463 in Pool 16. This area, located 1 mile north of Illinois City, is currently managed as a waterfowl refuge by the Illinois Department of Conservation. The purpose of this appendix is to present the development and evaluation of proposed improvements which will provide a water control structure system. This system will provide a moist soil management unit with controlled water levels, reduce sedimentation into the refuge area, and divert upland sedimentation from the refuge area. Approximately 1.55 square miles of overland area will drain into the moist soil management unit. The elevation area and capacity curves for the project are shown on plate A-1.
