Purpose

This work will determine whether continued operation and ownership of the Upper St. Anthony Falls (USAF) Lock project is in the federal interest, and if not, consider alternatives for disposal of the property.

Location

The USAF project is located on the Mississippi River in Minneapolis, Minnesota.

Description

The USAF Lock was ordered closed to navigation on June 9, 2015, under Section 2010 of the Water Resources Reform and Development Act of 2014.

Sections 1168 and 1225 of America’s Water Infrastructure Act of Oct. 24, 2018, directed the U.S. Army Corps of Engineers (USACE) to expedite completion of a disposition study for USAF and to examine partial disposal, environmental and natural resource improvement opportunities, and dam removal.

Section 356 of the Water Resources Development Act of Dec. 27, 2020 (WRDA 2020), directed that all or substantially all the lands around the USAF Lock be conveyed to the city of Minneapolis and that additional licenses and easements be granted to the city for any lands and features that are not otherwise conveyed.

Status

USACE published a draft disposition study report in January 2021, recommending full disposal of features not conveyed to the city under WRDA 2020. The remaining features include the lock structure, an upstream crossover wall, guidewalls, dolphins, and the downstream rock dike. The draft report invited outside parties to submit letters of interest in future ownership: at this time, no one has expressed interest. Formal tribal and Section 106 consultation began in February 2021 and is ongoing. A revised draft report is projected to be released for public review in June 2025.

Conveyance activities began in June 2022. In December 2022, USACE identified lands available for conveyance to the city. Due to ongoing navigation mission and Operations and Maintenance (O&M) needs, excess lands are subject to USACE reserved rights for O&M, and conveyance would exclude significant tracts of interest to the city. As a result, the city is interested in modifying the structure and functions under 10 U.S. Code 2695, to meet its goals prior to conveyance.

In March 2024, an outgrant was issued to the city of Minneapolis’ agent, Owámniyomni Okhódayapi. The outgrant is an interim step to full conveyance pending submittal of the abovementioned modification subject to 10 U.S. Code 2695. The disposition report can proceed now that the maximum extent of the conveyance of land is understood. If disposal of the remaining features is still recommended, a final report will be forwarded for approval by the Director of Civil Works.

Authority

Section 216 of the Flood Control Act of 1970 allows USACE to study the disposal of completed projects. Federal property disposal is managed by the General Services Administration, as governed by federal law.

Funding

The USAF disposition study cost estimate is $2.13 million, of which $1,697,523.50 has been allocated through fiscal year 2024. The fiscal year 2024 President’s Budget is $50,000. The updated study completion estimate is $450,000. Disposition studies are typically funded under the investigations appropriation and workplan.
