U.S. Army Corps of Engineers posts feasibility study and environmental assessment

November 6, 2017

The U.S. Army Corps of Engineers, St. Paul District, posted a copy of its draft Feasibility Report and Environmental Assessment, or EA, on the web for the proposed Souris Basin, North Dakota, Flood Risk Management project. The purpose of the feasibility study is to assess the interconnected system of reservoirs, levees and channels within this basin and recommend modifications to existing infrastructure and potential new measures to reduce the risk of flooding. The Corps is working in partnership with the Souris River Joint Water Resources Board, or SRJB, to complete the study. The Corps’ feasibility study is the first step toward a federal flood risk reduction project, and its purpose is to provide Congress with the information it needs to authorize a project for implementation.


The proposed project consists of the construction of what is currently referred to as the ‘Maple Diversion’ or high-flow bypass along with a short tieback levee east of the U.S. 83 Bypass within the city of Minot. The Maple Diversion is a feature of the SRJB’s larger Mouse River Enhanced Flood Protection Project.


The public review period will end Nov. 30, 2017. Official comments concerning the project can be submitted to David Potter, Environmental Planning Section, via email at: David.F.Potter@usace.army.mil
