The rate of water flowing in to Lake Red Rock peaked late Wednesday at 70,000 cubic feet per second, as the water level in the reservoir continues to rise. That’s according to the latest data from the U.S. Army Corps of Engineers, which is anticipating the lake to crest at over 774 feet on Friday. Since its peak, the in-flow of water at Lake Red Rock has declined swiftly, to around 50,000 cubic feet per second by Thursday afternoon. The out-flow of water at the Red Rock Dam has increased only slightly, but remains below 50,000 cubic feet per second.

The latest round of heavy rains and the recent disaster at Lake Delhi may have many people concerned about the safety of the dam at Lake Red Rock. John Holt, Assistant Operations Manager with the U.S. Army Corps of Engineers at Lake Red Rock says, simply stated, the dam is in good health. Holt says that dams like the one at Red Rock are part of a Federal program, and are carefully designed, with the foundation, structure and hydraulic factors carefully taken into consideration.

Holt says the dam was both well-designed and well-constructed, adding that there are routine processes followed to monitor the dam during regular and high-water operation, and data collected is compiled to provide the Corps of Engineers with a report on the “health” of the dam. The Red Rock Dam has been in service for just over 40 years, and was built to last for at least 100 years.
