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


The Upper Sioux Community is located south of the Minnesota River in Yellow Medicine County, approximately four miles south of the city of Granite Falls, Minnesota.


On January 9, 2019, the Upper Sioux Community requested assistance from the U.S. Army Corps of Engineers for riverbank stabilization on the Minnesota River under the Tribal Partnership Program. The Corps and the Upper Sioux Community signed a feasibility cost-share agreement on Jan. 28, 2020. The study began in April 2020. The study includes gathering information; formulating alternatives; analyzing costs, benefits, and environmental impacts; and recommending a tentative plan on how to address the erosion challenges.


A draft feasibility study report with integrated environmental assessment will be released for a 30-day a public review in October 2022. The final feasibility report will be submitted for approval in early 2023. Signing a project partnership agreement and starting the design phase may occur in summer 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.


Tribal Partnership program feasibility studies qualify for a waiver (currently $530,000) in which the first costs of the study are federally funded and the remaining amount is cost-shared between the federal government and the sponsor. The Tribal share is based on an ability to pay formula.

The design and construction phases are cost shared between the Federal and Tribal governments, with an additional waiver (currently $530,000) applied to the Tribal share. The remaining Tribal share is based on an ability to pay formula. Both the waived amounts and the ability to pay formulas are periodically updated.
