National Dam Safety Program. Struckhoffs Dam (MO 30100), Missouri - Kansas City Basin, St. Charles County, Missouri. Phase I Inspection Report.
Abstract
The dam is an earth structure built in a narrow draw in the uplands of the Missouri River Bluffs. An 8-inch steel pipe (principal spillway) is provided to drain off excess water from the lake. Additional spillways (emergency spillways), flat channels excavated in earth, are provided at each abutment. Our inspection and evaluation indicates that the spillway does not meet the criteria set forth in the guideilnes for a dam having the above size and hazard potential. The dam will begin to be overtopped by a flood having a discharge (peak and volume) equal to 35% of the PMF. The dam storage and principal spillway will contain a 1% chance flood (100-year flood) without overtopping the emergency spillway. Other deficiencies observed by the inspection team were tree growth starting on the downstream face, and shallow erosion channels on the downstream face and at the toe of the dam on the west slope.
