Book excerpt: Examination of available documents and visual inspection of Ischua Creek Watershed Dam No. 2 and appurtenant structures did not reveal conditions which constitute a hazard to human life or property. However, the dam has some deficiencies which require further investigation and remedial action. Drainage gullies were observed across the emergency spillway and emanating from the downstream east toe of the embankment. In addition, a bulge or slough was observed in the upper portion of the downstream east slope. It is recommended that these conditions be evaluated further by a qualified registered professional engineer. Using the Corps of Engineers screening criteria for review of spillway adequacy, it has been determined that the dam would not be overtopped under full PMF conditions. The PMF routed through the reservoir required 97 percent of the spillway outflow capacity. The spillway is, therefore, judged to be adequate. The investigations recommended should be completed within 12 months of notification to owner, and remedial actions resulting from these investigations completed in the subsequent 12 months.
