National Dam Safety Program. Deel Lake Dam (MO 31064), White Basin, Shannon County, Missouri. Phase I Inspection Report.
Abstract
Deel Lake Dam is an earthfill structure approximately 41 ft high and 365 ft long at the crest. The appurtenant works consist of an earth swale primary spillway at the north end of the embankment, an earth swale emergency spillway at the south end of the embankment and a 6 in. diameter steel drawdown pipe with a valve located at the downstream toe of the embankment. Our inspection and evaluation indicates that the combined spillway does not meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. The combined spillways will pass 74 percent of the Probable Maximum Flood without overtopping. Deficiencies visually observed by the inspection team were: (1) some minor erosion at north abutment-dam contact; minor seepage beyond the embankment toe in the old streambed and from the embankment at Sta. 2+80; and (4) lack of non-erodible control sections for the primary spillway.
