National Dam Safety Program. Lakeview Park Dam (MO 30288) Mississippi - Kaskaskia - St. Louis Basin, St. Francois County, Missouri. Phase I Inspection Report
This dam is composed of massive quantities of mill tailings from zinc-lead mining operations. The length from the left abutment (north) to the right end (south) is approximately 880 feet. The left 350 feet of the dam has been classified for purposes of this report as an emergency spillway. The principal spillway is uncontrolled and consists of approximately 250 feet of vegetated earth approach channel constructed through the left (north) abutment leading to a 15-inch diameter corrugated metal pipe culvert which crosses under the paved road that traverses the length of the dam. The emergency spillway is uncontrolled and consists of the paved road that traverses the dam. The low point in the profile of the emergency spillway is at the approximate location of the 15-inch pipe that serves as the principal spillway. The low-level outlet is a 10-inch cast iron pipe that runs from the reservoir through the dam to a manually operated gate valve that is housed in a downstream concrete block valve pit. Our inspection and evaluation indicates that the spillways meet the criteria set forth in the recommended guidelines for a small dam having a high hazard potential. The spillways will pass 55% of the Probable Maximum Flood without overtopping the dam. Lakeview Park Dam is in good condition. Deficiencies noted include the growth of small trees and brush on the downstream slope, erosion of the downstream slope, the lack of good vegetative cover on the downstream slope and the need to clean and reshape the approach channel to the spillways.
