National Dam Safety Program. Lake Lorraine Dam (MO 30433) Jefferson County, Missouri. Phase I Inspection Report.

Abstract

Lake Lorraine dam is an earth-fill dam with a notch spillway in the right abutment. The spillway is cut into a combination of earth and rock, and is paved with unreinforced concrete. The outlet works is a 30-inch corrugated metal pipe; this pipe is blocked on the upstream side with a piece of plywood and also a metal plate. The metal plate could not easily be removed in time of emergency. The inspection team visually observed animal burrows and a thick cover of brush and small trees on the downstream slope. The upstream slope has a lesser but appreciable brush cover. Our evaluation of the spillway size indicates that it does not meet the criteria in the guidelines.
