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.

摘要

This statement concerns a proposal by the Rock Island District, Corps of Engineers (NCR), to perform a work pursuant to the Environmental Management Program (EMP) - Habitat Rehabilitation and Enhancement Program (HREP) at Andalusia Refuge, Rock Island County, Illinois. This work involves dredging, excavation, levee construction, concrete construction, electrical work, and rock placement. An Environmental Assessment addressing effects of the proposed project has been prepared for public review. Project objectives are to: enhance migratory waterfowl habitat by providing adequate vegetation and reliable loafing and resting areas; retard the loss of aquatic habitat by reducing sedimentation into the Refuge and Dead Slough; enhance aquatic habitat in Dead Slough by channel excavation and by providing year-round water access to the river. It is proposed that the following information be collected to evaluate performance of the project: summer and winter measurement of dissolved oxygen in Dead Slough; soundings of Dead Slough and fish access channel excavations; and sedimentation measurements with in the MSMU. Waterfowl survey data, vegetation inventories, and fishery survey data from Dead Slough may be collected by other agencies but will not be used for project performance evaluation. The District Engineer has reviewed the project outputs and determined that implementation of the identified plan is justified and in the Federal interest. (kt)
