Based on the evaluation of the conditions as they existed on the date of inspection July 11 and 18, 1978 and as revealed by visual observations, the condition of Tyrone Reservoir No. 1 is assessed to be fair. It is reported that the drawdown facility for the reservoir is not functional. It is therefore recommended that the owner assess the functional condition of the operating facilities. The spillway capacity is classified to be seriously inadequate 27 PMF, because it is estimated that overtopping would result in failure of the dam and the damage potential would be significantly higher than that which would exist prior to overtopping. It is recommended that the owner reevaluate the spillway capacity using more accurate analysis techniques and determine the nature and extent of improvements required to increase the spillway capacity. It is further recommended that the owner provide around-the-clock surveillance during unusually heavy runoff to detect possible problems and develop a formal warning system to alert the downstream residents in the event of an emergency.
