    National Loon Center Facility, Public Docks and Shoreline Protection Project, Crosslake, MN: Review Outgrant Request (REC, ENS)

    The National Loon Center Foundation, a 501(c)(3) tax-exempt non-profit organization, is proposing a National Loon Center Facility, Public Docks and Shoreline Protection Project on U.S. Army Corps of Engineers land at the Cross Lake Recreation Area. Also proposed is the development of shoreline protection zones with plantings and a boardwalk. The National Loon Center Foundation has presented a Land Use Application requesting a lease of the day use area at the Cross Lake Recreation Area. The St. Paul District is in the process of evaluating the application in accordance with the governing instructions to make an objective determination of how this proposed project fits in the master plan and affects the Corps’ flood risk management, recreation, and environmental stewardship mission and current users of the project.
  • Project Alteration Reviews: Section 408

    Section 14 of the Rivers and Harbors Act of 1899 authorizes the Secretary of the Army to grant permission for alterations to existing U.S. Army Corps of Engineers projects under certain circumstances. Authority to approve alterations has been delegated to the District Commander in most cases, although certain alterations require approval from the Director of Civil Works at the Corps’ headquarters. Section 408 provisions apply to works that were built by the Corps and are locally maintained, such as local flood control projects. They also apply to works that are operated and maintained by the Corps, such as locks and dams. Proposals submitted for Section 408 review and approval undergo a rigorous engineering, policy and environmental review by the Corps and, if required, independent external peer review.

    Disposition Study, Lower St. Anthony Falls Lock and Dam, and Lock and Dam 1, Upper Mississippi

    A Section 216 study will investigate the appropriate future disposition of Lower St. Anthony Falls (LSAF) Lock and Dam and Lock and Dam 1, located on the Mississippi River in Minneapolis, Minnesota. The LSAF Lock and Dam was constructed as part of the Minneapolis Upper Harbor project in 1956 as authorized by the Rivers and Harbors Act of 1937. Lock and Dam 1 was originally constructed in 1917 and was modified in 1932 under the authority of the River and Harbor Act of 1930. The U.S. Army Corps of Engineers operates and maintains the two sites. Both locks have been affected by the decrease in the demand for navigation services stemming from the closure of Upper St. Anthony Falls Lock and Dam on June 9, 2015. This disposition study will examine the benefits and costs of continuing to operate LSAF and Lock and Dam 1.
  • Mississippi River Locks and Dams 2–10 Non-Structural Embankment Repair

    Non-structural embankment repair projects at Locks and Dams 2 through 10 will address restoring embankments to meet current design standards. Most dam embankments are currently protected from the erosive forces of water by a layer of riprap placed along the embankment’s length. When the riprap eventually erodes, the embankment itself will erode if more protection is not added. The U.S. Army Corps of Engineers has designed and placed berms and small islands to assist in reducing wave action and wind fetch within pools created by the locks and dams. Reducing these forces increases the longevity of the embankment protections.
  • Planning Assistance to States (PAS): Red River Basin Long Term Flood Study

    The Red River of the North rises in Lake Traverse near Wheaton, Minnesota and flows north towards Canada and ultimately to Lake Winnipeg. The Red River Basin Commission (RRBC) produced the Long Term Flood Study (LTFS) in 2011 after the 2009 event. Minnesota and North Dakota expressed the need for a coordinated, comprehensive, proactive plan that responds to and mitigates flooding and flood damages throughout the Red River Watershed.
