Purpose

Determine whether or not continued operation and ownership of Upper St. Anthony Falls Lock and Dam (USAF) is in the federal interest, and if not, provide supporting information for deauthorization of the project purposes and disposal of the property.

Location

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

Description

USAF was closed to navigation on June 9, 2015, as ordered by Section 2010 of the Water Resources Reform and Development Act of 2014. The U.S. Army Corps of Engineers continues to operate USAF for flood damage mitigation.

A combined disposition study for Upper St. Anthony Falls, Lower St. Anthony Falls and Lock and Dam 1 was begun in spring 2018. On October 24, 2018, America’s Water Infrastructure Act, directed the Corps to expedite the study for Upper St. Anthony Falls and to examine a partial disposition alternative in which the Corps retains operation and maintenance of the flood risk management features, while making other portions of the project available for disposition and redevelopment.

Status

The Corps began the disposition study for Upper St. Anthony Falls in May 2019. Public information meetings were held in August 2019.

A draft report will be available for public review and comment in summer 2020. The final draft report will be complete in late 2020 and will be forwarded for approval by the Director of Civil Works in early 2021. If deauthorization and disposal are recommended, the report will be forwarded for Congressional action. An environmental assessment is being prepared in compliance with the National Environmental Policy Act.

Additional studies and environmental assessments may be required if the recommendation includes partial disposal. These studies would likely be funded by a non-federal sponsor or would require authority for a new start feasibility study if done in partnership with the federal government. A separate disposition study will be conducted for Lower St. Anthony Falls and Lock and Dam 1.

Authority

Section 216 of the Flood Control Act of 1970 allows the Corps 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.

Funding

The cost of the study is funded under the investigation appropriation.
