Abstract:

Based on the evaluation of the existing conditions, the condition of Big Elk Lake Dam is considered to be good. The flood discharge capacity of the dam was evaluated according to the recommended criteria and it was found that the dam cannot pass the recommended spillway design flood 100-year flood without overtopping the dam. THerefore, flood discharge capacity of the dam is classified to be inadequate. The following recommendations should be implemented as soon as possible or on a continuing basis. 1 The owner should determine the nature and extent of improvements required to provide adequate spillway capacity. 2 The owner should investigate the need to install low level outlet facilities or prepare plans to lower the lake in the event of an emergency. 3 Around-the-clock surveillance should be provided during unusually heavy runoff and a formal warning system developed to alert the downstream residents in the event of emergencies. 4 The owner should develop a formal operating and maintenance plan and inspect the dam regularly and perform necessary maintenance.
