The study will assess the problems and opportunities being faced by the Lower Sioux Indian Community on their tribal lands and make recommendations related to erosion along the Minnesota River adjacent to and impacting those lands.


The Lower Sioux Indian Community is located south of the Minnesota River in Redwood County, approximately 2 miles south of the city of Morton, Minnesota.


On May 8, 2019, the Lower Sioux Indian Community requested the assistance of the U.S. Army Corps of Engineers for riverbank stabilization on the Minnesota River. Federal funding for the study was provided in July 2020. A feasibility cost-share agreement between the Corps and the Lower Sioux Indian Community was signed on September 16, 2020.


The tentatively selected plan was endorsed by Mississippi Valley Division with approval to release the draft report on June 22, 2021. The Feasibility Study Report was released for agency technical review and public review in September 2021. The tentatively selected plan includes regrading and riprap placement along approximately 1500 feet of Minnesota River shoreline. The study is scheduled to be completed in July 2022 with design in fiscal year 2022 and construction in fiscal year 2023.


The Tribal Partnership Program is authorized by Section 203 of the Water Resources Development Act of 2000 (Public Law 106‒541). The Tribal Partnership Program provides authority for the U.S. Army Corps of Engineers to work with Indian nations to study and determine the feasibility of carrying out projects that will substantially benefit Indian nations.
