Mississippi River: Lock & Dam 3 Navigation Safety and Embankments, Minnesota and Wisconsin
Location/Description
|
Lock and Dam 3 is a navigation dam and lock on the Mississippi River 6 miles upstream from Red Wing, Minn. Its position on a bend in the river makes downbound navigation difficult because of an outdraft current that tends to sweep towboats and barges away from the lock toward the gated part of the dam. The outdraft current has resulted in many accidents, including 11 incidents since 1968 when tows collided with the gated part of the dam. A related problem is with the low and weak embankments on the Wisconsin side.
Navigation accidents can render the four roller gates inoperable, resulting in overtopping and erosion of the embankments. The three Wisconsin side embankments divide the 8-foot head at the dam into three steps and work together as part of Lock and Dam 3. Failure of the embankment system could result in accidental drawdown of Pool 3 with significant economic and environmental consequences.
|
Status
|
A Record of Decision was signed on April 3, 2007, and endorsed by Corps' Headquarters, which approved a project to address the navigation safety problem and strengthen the embankments. The Office of Management and Budget made a positive determination of budgetability on May 5, 2008.
The recommended plan includes strengthening the Wisconsin embankments and constructing an extended landward guide wall with channel modifications to improve navigation safety.
The district is progressing with designs on all features and is developing plans and specifications for the initial stage of construction on the embankments. Construction of the spot dikes on the upstream portion of the project is scheduled to begin in fiscal year 2010.
Environmental mitigation is required to restore 313 acres to floodplain forest. Acquisition of real estate is ongoing, and approximately 110 acres of eligible land has been purchased.
Construction of the spot dikes on the upstream portion of the project is scheduled to begin in fiscal year 2010.
