National Dam Safety Program. Lake Torino Dam (MO 30552), Mississippi - Kaskaskia - St. Louis Basin, Franklin County, Missouri. Phase I Inspection Report.

Abstract : Lake Torino Dam is an earthfill structure approximately 38.5 ft high and 570 ft long at the crest. The appurtenant works consist of a 10-in. diameter steel pipe primary spillway located near the center of the dam and a grass-covered earth emergency spillway located at the north end of the dam. Our inspection and evaluation indicates that the combined spillways do meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. The combined spillways will pass 57 percent of the Probable Maximum Flood without overtopping. Deficiencies visually observed by the inspection team were: (1) erosion at the contacts of the dam with the north and south abutments; (2) tree and brush growth along upstream and downstream faces of dam; (3) animal burrows along upstream and downstream faces; (4) a few small sloughs on upstream face; (5) seepage areas on downstream face and wet areas at toe of dam; (6) debris and brush around intake to primary spillway; (7) outlet channel of primary spillway overgrown with trees and brush; and (8) swale at south end of dam.
