National Dam Safety Program. Lake Panorama Dam & Lake Panorama Dike (NJ00816 & NJ00828), Wallkill River Basin, Tributary to Wallkill River, Sussex County, New Jersey. Phase I Inspection Report.

Lake Panorama Dam is an earth embankment with a spillway consisting of three 12-inch concrete culvert pipes that transversely penetrate the dam. In addition to the dam, lake Panorama Dike located to the south or left of the dam, impounds Lake Panorama. An unpaved road is located on the crests of both the dam and dike which are separated by a distance of approximately 200 feet. Based on visual inspection, past operational performance, and Phase I engineering analyses, Lake Panorama Dam and Lake panorama Dike are assessed as being in fair overall condition. The spillway of the dam is capable of passing the designated spillway design flood 100-year storm without an overtopping of the dam or dike and, therefore, is assessed as being adequate. Variations in the slope of the downstream face of the dam together with areas of seepage were observed, indicating the possibility of embankment distress. In addition, seepage at the toe of the dike was observed.
