The Stormwater Diversion Channel and Associated Infrastructure (SWDCAI) includes a 30-mile stormwater diversion channel, a diversion outlet, and aqueducts on the Maple and Sheyenne Rivers.
Other infrastructure includes:
- Fourteen drainage inlets
- Three railroad crossings

Delivered by: U.S. Army Corps of Engineers and contractors
The Southern Embankment and Associated Infrastructure (SEAI) includes a 20-mile earthen embankment and three gated control structures:
- Diversion Inlet Structure
- Wild Rice River Structure
- Red River Structure
Each structure will have large radial-arm gates that raise and lower during project operations to control flooding.
The SEAI also involves constructing several transportation features, including an I-29 bridge crossing and 4-mile grade raise as well as county and township road crossings.
Mitigation Projects
Delivered by: U.S. Army Corps of Engineers and the MFDA in partnership with city and county governments
The comprehensive project includes numerous mitigation features, including:
- Upstream mitigation area, where flowage easements will be acquired, property/structures will be removed, and cemeteries will undergo mitigation to protect the property and viewshed
- Levees in Oxbow-Hickson-Bakke and Christine, North Dakota, and Wolverton, Minnesota
- Wetland mitigation projects in Oxbow and at Drain 27 in North Dakota
- Complementary flood-mitigation projects on the Lower Otter Tail River and in Georgetown, Comstock and Wolverton, Minnesota
The comprehensive project will follow an Adaptive Management and Monitoring Plan to monitor environmental mitigation project performance and any environmental changes after operations.
In-Town Features
City and county governments are working on in-town protection measures. Also known as Local Entity Flood Protection & Associated Infrastructure (LFPAI), this includes:
- Levees and floodwalls
- Stormwater lift stations
- Road improvements and grade raises
