Determine whether or not continued operation and ownership of Lower St. Anthony Falls Lock and Dam and Lock and Dam 1 are in the federal interest, and if not, provides supporting information for deauthorization of the project purposes and disposal of the property.
Lower St. Anthony Falls Lock and Dam and Lock and Dam 1 are both located on the Mississippi River in Minneapolis, Minnesota.
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.
The disposition study for Lower St. Anthony Falls Lock and Dam and Lock and Dam 1 will commence in fall 2021. The Corps will hold meetings with the public, resource agencies and non-governmental agencies to begin the environmental scoping process. A draft report will be available for public comment in 2022. The study is scheduled to be complete in 2023.
As per Section 1168 of America’s Water Infrastructure Act of 2018, in addition to considering no action and full deauthorization and disposal of the projects, the study must consider full or partial removal of the dam at each site. An environmental assessment or environmental impact statement will be prepared in compliance with the National Environmental Policy Act.
If disposal of the properties is not recommended, additional studies may be performed to modify the projects to serve existing or new authorized purposes or for additional uses identified by a potential non-federal sponsor and authorized under a new start feasibility study.
Section 216 of the Flood Control Act of 1970 allows the Corps of Engineers to study completed projects or their operation when found advisable due to significantly changed physical or economic conditions. Federal property disposal is managed by the General Services Administration as governed by federal law.
The cost of the study is $1.3 million funded under the investigations appropriation.
