Abstract:

The visual inspection and review of available design and construction data indicate the Valley View Lake Dam is in poor condition. The deteriorated condition of the spillway walls, severe erosion of the spillway discharge channel, and seepage observed at the downstream toe are the primary deficiencies which cause concern for the safety of this facility. The dam in its present condition is considered to be unsafe, non-emergency. The hydrologic and hydraulic computations indicate that the combination of reservoir storage and spillway discharge capacity will pass only 32 of the PMF prior to overtopping the embankment. Overtopping the dam could cause failure, which would lead to a significant increase in downstream loss of life and property damage. Therefore, the spillway for Valley View Lake Dam is considered to be seriously inadequate. Measures recommended for immediate action are listed.
