Senator Young & Olson Dam Rehabilitation
Sponsor: Pembina County Water Resource District
PRELIMINARY DRAFT SUPPLEMENTAL WATERSHED PLAN-EA
TONGUE RIVER DAM #M3 (SENATOR YOUNG DAM) AND TONGUE RIVER DAM #T-7-1 (OLSON DAM)
The purpose of the project is to bring the Tongue River Dam #M-3 (Senator Young Dam) and Tongue River Dam #T-7-1 (Olson 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 to public safety downstream and to mitigate flooding issues for the area downstream of the dams.
The watershed rehabilitation planning process is underway. An initial public scoping meeting was held March 5, 2020. Currently NRCS and Houston 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.
