Description This report summarizes the Dam Safety Office’s observations and findings of our May 3, 2017, inspection of the breached Bonasa Breaks Ranch Dam, and our subsequent engineering analyses. Our primary objective was to determine the causes of the April 13, 2017, dam breach failure of the Bonasa Breaks Ranch Dam by evaluating the hydrologic response of the reservoir and spillway to potential and design hydrologic and hydraulic operating conditions.
