The basic objectives of the Levee Safety Program are to develop balanced and informed assessments of levees within the program; evaluate, prioritize and justify levee safety decisions; and recommend improvements to public safety associated with levee systems. The Corps created the National Levee Database, inventoried all levees in the program and improved inspection procedures. The Corps is developing a method to manage its levee systems and is reviewing and revising current levee-related policies and procedures.

The tow rail system is integral to the operation of each of the Mississippi River Locks and Dams 2 through 10. It is attached to the top of the lock guidewall and helps guide tows through the lock chamber. Each system is comprised of an operating unit, rail and traveling kevel or “mule.” The Locks and Dams 2 through 10 tow rail systems have been deteriorating over the past several years, requiring rehabilitation of these systems.

The Navigation and Ecosystem Sustainability Program (NESP), seeks to provide a safe, reliable, cost effective and environment sustainable waterborne navigation system by implementing switchboats at five locks, constructing mooring cells and seven new 1,200 foot locks. NESP will restore the aquatic and terrestrial habitat to a more natural condition on more than 100,000 acres throughout the system through a wide variety of ecosystem projects.

Maintenance of the dam spillway gates are required to avoid degradation and eventual replacement. Benefit – cost analyses show it is economically favorable to maintain the gates rather than the replacement option. There are also reliability and safety concerns with allowing the gates to degrade to the point that they must be replaced. formed on site.

The purpose of the DMMP is to prepare a coordinated long-term plan for managing dredged material in Pool 9. This plan was initiated due to needs for dredged material management upland placement sites, especially in the upstream reach of the pool. The Pool 9 Dredged Material Management Plan (DMMP) study area is located between Lock and Dam 8 at Genoa, Wisconsin, and Lock and Dam 9 near Lynxville, Wisconsin, spanning more than 31 river miles from 679.2 to 648.0. The study area includes several communities near the main navigation channel including Lansing, Iowa, and De Soto, Wisconsin.
