Abstract:

This report assesses the general condition of the dam with respect to safety, based on available data and on visual inspection, to determine if the dam poses hazards to human life or property. The Turkey Creek dams acting as a system are in the high downstream hazard potential classification. Failure of the dams would threaten the life and property of approximately eight families downstream of the dams and cause appreciable damage to highway E which is 1.2 miles downstream of the dams. The inspection and evaluation of the dams indicate that the spillways in each dam will not meet the criteria set forth in the guidelines for dams having their size classification and hazard potential. The emergency spillway for Lake Julia Dam Mo. 31101 will pass only 9 percent of the PMF before the dam embankment is overtopped. The emergency spillway for Lake of the Pines Dam Mo. 31109, will pass only 20 percent of the PMF before the dam embankment is overtopped. The emergency spillway for Turners Dream Lake Dam Mo. 31108 will pass only 20 percent of the PMF before the dam embankment is overtopped. The discharge structure for Lake Janna Dam Mo. 31602 will pass only 25 percent of the PMF before the dam embankment is overtopped.
