National Dam Safety Program. Las Brisas Lake Dam (MO 30541), Mississippi - Kaskaskia - St. Louis Basin, Franklin County, Missouri. Phase I Inspection Report.
Abstract
The purpose of this inspection of the Las Brisas Lake Dam 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. The guidelines used in the assessment indicate that this dam is in the high hazard potential classification. The dam is in the intermediate size classification, since it is greater than 40 ft high but less than 100 ft high. The inspection and evaluation indicate that the combined spillways do not meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. The combined spillways will pass 58 percent of the Probable Maximum Flood without overtopping. The guidelines require that a dam of intermediate size with a high downstream hazard potential pass the PMF. The 100-year frequency flood will not overtop the dam. The 100-year flood is one that has a 1 percent chance of being exceeded in any given year.
