    Mississippi River Lock and Dam 5A Embankment and Levee Certification

    The Lock and Dam 5A embankment is located along the Mississippi River about 3.5 river miles above Winona, Minnesota, and about 3 river miles below Fountain City, Wis. FEMA is verifying that all levees recognized as providing protection from the base flood meet the requirements outlined in 44 CFR 65.10. This code requires that specific structural requirements must be certified by a registered professional engineer or a federal agency with responsibility for levee design. The city of Winona is performing this certification for the flood risk management project with the Corps providing an analysis of the Lock and Dam 5A embankment in support of that certification.
