National Dam Safety Program. Wright Lake Dam (MO 31062), Mississippi - Kaskaskia - St. Louis Basin, Bollinger County, Missouri. Phase I Inspection Report.
Abstract
Wright Lake Dam, Missouri Inventory No. 31062, was inspected. The dam is an earth dam constructed for recreational purposes. The St Louis District (SLD), Corps of Engineers has classified this dam as having a high hazard potential; we concur with this classification. The hazard zone length estimated by the SLD extends approximately two and one-half miles downstream of the dam. Within this zone are Reed Lake Dam (MO 30859) and more than six occupied dwellings. Due to the small distance to the nearest downstream residences and Reed Lake Dam and the potential for damage due to outflow during overtopping, it is recommended that 100 percent of the Probable Maximum Flood (PMF) should be used as the spillway design flood. The PMF is defined as the flood evvent that may be expected to occur from the most severe combination of critical meteorological and hydrologic conditions that are reasonably possible in the region.
