Abstract:

Based on the criteria established for these studies, Elk Lake Dam is judged to be in fair condition. The recommended Spillway Design Flood SDF for the size and hazard classification of the dam is the Probable Maximum Flood PMF. The existing spillway will pass about 84 percent of the PMF before overtopping of the dam occurs. The spillway capacity is rated as inadequate. Several deficiencies were observed at the dam. The most serious is the probable lack of an adequate impervious barrier through the dam. Although some maintenance has been performed, the existing maintenance program could be upgraded. The following remedial measures, listed in approximate order of priority, are recommended to be undertaken by the Owner without delay 1 Clear brush and debris on and adjacent to the dam. 2 Engage the services of a professional engineer experienced in the design and construction of dams. Utilize his advice in removing the trees on and near the embankment. If any seepage becomes evident after the brush, trees, and debris are removed, the condition should be assessed by the engineer. 3 Fill the slots by the spillway bridge with concrete or other suitable impervious material. 4 Fill the burrowing animal hole adjacent to the spillway with suitable impervious material.
