National Dam Safety Program. Burton-Duenke Dam Number 4 (MO 31713), Missouri - Osage - Gasconade Basin, Camden County, Missouri. Phase I Inspection Report

The purpose of the inspection was to make an assessment of the general condition of the dam with respect to safety, based upon available data and visual inspection, in order to determine if the dam poses hazards to human life or property. Inspection and evaluation indicated that the spillway does not meet the criteria set forth in the guidelines. The spillway will not pass the probable maximum flood without overtopping the dam but will pass 20 percent of the probable maximum flood. The spillway will pass the flood which has a one percent chance of occurrence in any given year (100-year flood). The spillway design flood recommended by the guidelines is the probable maximum flood. The probable maximum flood is defined as the flood discharge which may be expected from the most severe combination of critical meteorological and hydrologic conditions which are reasonably possible in the region. Based on visual observations, this dam appears to be in good condition.
