The Corps has a lake operation manual that documents how they are to operate Table Rock Dam. However, I'm not sure they ever anticipated lake levels this high since up till 2008, the previous lake record was 932.5 in 1961. The Corps web site, referenced above, just says the auxillary gates would only be used when the lake level exceeds 937. These gates are only intended to be used to save the dam from catostrophic failure, such as what a breach of the dam at Beaver could cause or some other near overtopping of the Table Rock Dam or failure of one of the flood gates. This record level also puts the dam under "record" pressure that it has not experienced before. Once the flood pool fills up at a Corps lake, the Corps is then out of the "flood control" business and it is up to Mother Nature (and God).
