The U.S. Army Corps of Engineers has evaluated potential control options and technologies at Brandon Road Lock and Dam to prevent the upstream Interbasin transfer of Aquatic Nuisance Species (ANS) while minimizing impacts to Illinois Waterway uses and users. This effort has identified a recommended plan. Implementation of the recommended plan requires congressional authorization.
The project was authorized for construction in the Water Resources Reform and Development Act (WRRDA) of 2014. It provides protection along the east bank of the Cedar River. It includes earthen levees, floodwalls, and closure structures for a total length of 3.15 miles.

LaGrange Lock, located on the Illinois Waterway at river mile 80.2, was put into service in 1939 and is in need of a major rehabilitation of lock concrete, electrical and mechanical systems.
NESP is a long-term program of ecosystem restoration and navigation improvements for the Upper Mississippi River System (UMRS). NESP will improve system capacity and reduce commercial traffic delays through construction of 7 new 1,200-foot locks, mooring cells and switchboat implementation.
