ST. PAUL, Minn. – The U.S. Army Corps of Engineers, St. Paul District, is closing Lock 10, near Guttenberg, Iowa, to all navigation from Dec. 12 to March 4, 2018.
Although Dec. 12 is the latest the lock will be open this season, the closure date is subject to change pending environmental factors – such as the formation of ice – that could dictate an earlier closure.
“The purpose of this closure is to make repairs to concrete and armor plate within the lock chamber,” said Sam Mathiowetz, Lock and Dam 10 lockmaster. “Scheduling this maintenance during the non-navigation season is important so as to minimize the impact to commercial and recreational traffic.”
Repair work is scheduled to begin mid-December, taking several months to complete, and will make for a safer passage by creating a smoother transition where the miter gate and the lock chamber wall meet, said Mathiowetz.
The nearly 600 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 St. Paul District Fiscal Year 2015 $100 million budget, nearly 1,600 non-Corps jobs were added to the regional economy as well as $155 million to the national economy.
