ResponseODSP did not hear about this dam until after the fact. The dam was not inventoried and therefore not inspected by our program. Staff inspected the breached dam and surveyed the damage downstream. A letter was sent to the owner indicating that if the dam were to be reconstructed that a construction permit from our office would be required.
Volume released at failure (ac-ft)28.6
Additional Remarks or Updates1 Elderly woman was killed. Apparently she left her house to check on her goat and was swept away in the floodwaters. Unknown if this occurred during dam failure or just during flooding event.
