Incident Description |
The area received 5 inches of rain in less than 6 hours. It appeared that the center of the crest was approximately 1 foot lower than the left and right ends. The original principal spillway was grouted shut and a new spillway was installed between August 2005 and April 2006 based on historical aerial photographs of the dam. The dam had no emergency spillway. |

Response |
ODSP 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. |
Additional Remarks or Updates |
1 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. |
