National Dam Safety Program. Becker Lake Dam (MO 31495), Missouri - Kansas City Basin, Franklin County, Missouri. Phase I Inspection Report.
Abstract
The embankment is an earthen structure approximately 295 feet in length and 30 feet in height. The principal spillway is an uncontrolled SCS type hood inlet pipe spillway. The emergency spillway is an uncontrolled earthen channel excavated in the right abutment. The channel is elliptical in shape with a bottom width of approximately five feet and side slopes of approximately 1V on 3.3H. There is a training dike on the left (inside) of the channel. Our inspection and evaluation indicates that the spillways do not meet the criteria set forth in the recommended guidelines for a small dam having a high hazard potential. The spillways will pass 14% of the Probable Maximum Flood without overtopping the dam. Becker Lake Dam is in excellent condition and is very well maintained. The only deficiencies noted are inadequate spillway capacity and the lack of seepage and stability analyses as required by the guidelines for all dams having a high hazard potential.
