PRELIMINARY DRAFT SUPPLEMENTAL WATERSHED PLAN/ENV ASSESSMENT

UPPER TURTLE RIVER DAM #9 (LARIMORE DAM)

The purpose of the project is to bring Upper Turtle River Watershed Middle South Forest River Watershed Dam No. 9 (Larimore Dam) into compliance with current NRCS and North Dakota Department of Water Resources dam performance, design, and safety standards.  The need for the project is to improve dam safety to minimize risk for downstream residents, to mitigate flooding issues for the area downstream of the dam, and to provide recreation opportunities at the dam site in the future.

Current Status

The watershed rehabilitation planning process is underway. An initial public scoping meeting was held July 19, 2021.  The sponsor selected their preferred alternative on 6/4/2025. Section 106 Consultation was completed on 10/15/2025.  In 2025, NRCS was directed to separate the Environmental Assessment (EA) from the Watershed Plan to meet new National Environmental Policy Act guidance. The Plan, including EA and FONSI as Appendix E, was posted to this website on June 3, 2026. Both documents will be submitted to the National Water Management Center for review in June 2026. Following edits, the revised plan will be submitted to NRCS National Headquarters for review. After the Draft Watershed Plan is completed, a public meeting, formal public comment period, and final agency and tribal notifications will be conducted.
