Corps of Engineers awards Lock and Dam 1 scour protection contract

ST. PAUL, Minn. – The U.S. Army Corps of Engineers, St. Paul District, awarded a $1.9 million contract to place riprap in the Mississippi River downstream of Lock and Dam 1 in Minneapolis, Sept. 21.

The contractor, LS Marine, Inc., from St. Paul, Minnesota, will place nearly 20,000 tons of riprap and bedding downstream of the lock. Work is expected to begin this fall and be completed in the fall of 2016. 

The project will protect the lock and dam structure from additional scouring by placing the riprap protection from immediately downstream of the spillway to approximately 150 feet downstream. 

Material and equipment will be brought to the site by barge and offloaded on the island directly south of the lock.  

The nearly 650 U.S. Army Corps of Engineers, St. Paul District, employees working at more than 40 sites in five upper-Midwest states serve the American public in the areas of environmental enhancement, navigation, flood damage reduction, water and wetlands regulation, recreation sites and disaster response. Through the Corps’ Fiscal Year 2014 $100 million budget, nearly 1,600 non-Corps jobs were added to the regional economy as well as $155 million to the national economy.
