Larimore Dam Rehabilitation
Sponsor: Grand Forks County Water Resource District
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.
The watershed rehabilitation planning process is underway. An initial public scoping meeting was held July 19, 2021. Currently NRCS and HDR Engineering are developing the preliminary Draft-EA and anticipate submitting to the National Water Management Center for review in 2023. Following edits, the revised plan will be submitted to NRCS National Headquarters for review. After the Draft Plan-EA is completed a public meeting, formal public comment period, and final agency and tribal consultations will be conducted.
