Introduction

The U.S. Fish & Wildlife Service has accepted certain management rights and some land at the former Savanna Army Depot, which is located along the Mississippi River in northwestern Illinois.

The Savanna Army Depot officially closed on March 18, 2000, as part of the Base Realignment and Closure Act. The former Depot included a total of 13,062 acres that have been transferred to four agencies: the Service; the Local Redevelopment Authority; the U.S. Army Corps of Engineers; and the Illinois Department of Natural Resources.

On September 26, 2003, the Department of Defense agreed to transfer 9,404 acres of land to become the Lost Mound Unit of the Upper Mississippi River National Wildlife and Fish Refuge. A total of 3,022 acres was actually transferred in fee at the time of the signing of the Memorandum of Agreement. The remaining acreage will be transferred in the future as parcels are certified clean from environmental contaminants. In the meantime, the Service will manage wildlife and habitat on all 9,404 acres.

The name "Lost Mound" refers to local folklore of a nearby post-glacial hill, or mound, that provides a backdrop for the sand prairie uplands of the Savanna Depot. The mound did not appear on early maps of the region, however the "lost" mound has since been found and is featured on recent topographical maps.

CCP Completed

The Lost Mound Unit was included in a comprehensive conservation plan (CCP) completed by the Upper Mississippi River National Wildlife and Fish Refuge in 2006. The CCP is intended to outline how the Refuge will fulfill its legal purpose and contribute to the National Wildlife Refuge System's wildlife, habitat and public use goals. The plan articulates management goals for the next 15 years and specifies the objectives and strategies needed to accomplish these goals. While the planned future condition is long-term, we anticipate that the plan will be updated every 5 to 10 years based on information gained through monitoring habitat and wildlife, as well as recreational usage.
