Fact Sheet

Navigation Study

Following allegations by two senior Corps economists, the Army's Inspector General concluded that senior Corps officials had exaggerated the benefits of longer Mississippi River locks. Even so, the Corps continues to press for the $1.2 billion lock expansion project, ignoring the real transportation needs of farmers and the environment.

Despite the complaints of barge boosters, there has been no increase in Upper Mississippi River barge traffic in the last two decades. In particular, barge traffic has not increased since 1993 – contradicting Corps forecasts. Even so, the demand for longer locks continues.

Instead of developing new traffic forecasts models – as the National Academy of Sciences suggested – the Corps continues to rely on outdated, discredited models or ignores the need for reliable traffic forecasts altogether. And, the Corps has proposed a new planning process to study river traffic needs that is based on Corps opinion rather than economics, using "scenarios" developed by navigation industry consultants based upon overly optimistic estimates of foreign demand for American grain.

Unlike barge shipments, rail and truck shipments of value-added products like corn oil have increased dramatically in the last two decades. Value-added processing also creates jobs in rural communities rather than shipping jobs oversees. The Corps also continues to ignore less costly measures that can immediately reduce river congestion, including scheduling the arrival of barges to congested locks.

Additional barges would kill tens of thousands of fish and destroy thousands of acres of side channels and marsh plants used by migrating waterfowl. Even so, the Corps has not adequately studied the impacts of additional barges on river wildlife. Instead, the Corps has proposed to dramatically cut funding for the Environmental Management Program, the primary habitat restoration and research program for the Upper Mississippi River, and has refused to update illegal channel maintenance plans. The Corps has also narrowly focused on the incremental impacts of additional barge rather than the long-term impacts of dams, levees and channel training, and ignores the impacts of additional truck traffic to terminals.
