National Dam Safety Program. Grisham Lake Dam (MO 31574), White River Basin, Howell County, Missouri. Phase I Inspection Report.
Abstract
Grisham Lake Dam is an earthfill structure approximately 25 ft high and 765 ft long at the crest. The appurtenant works consists of an earth cut swale spillway at the north abutment. Our inspection and evaluation indicates that the spillway does not meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. The spillway will pass 22 percent of the Probable Maximum Flood without overtopping. The embankment appears to be in good condition. Deficiencies visually observed by the inspection team were: (1) Few small trees on upstream face of embankment; (2) very dense brush and tree growth on downstream face of embankment; (3) lack of wave protection for upstream face of embankment; (4) minimal elevation difference between the spillway crest and the low point of the dam crest; and (5) lack of non-erodible spillway control section.
