The stop-logs in the standpipe (the concrete structure in front of the dam that serves as an emergency overflow) had deteriorated, allowing water to drain through. Our camp rangers worked on slowing the leak and the OA had a crew that built and installed new stop-logs. We thought that worked, but apparently the concrete at the bottom of the structure has decayed and water is going under the stop-logs. As you can see from the above picture, the lake has totally drained. We have met on-site with an engineer who specializes in dams and are waiting for information back from DEP on how to proceed.
