National Dam Safety Program. Upper Lake Minnie Ha-Ha Dam (MO-30643, Lower Lake Minnie Ha-Ha Dam (MO-30644), Lake Minnie Ha-Ha Development, Mississippi - Kaskaskia - St. Louis Basin, Genevieve County, Missouri. Phase I Inspection Report
The purpose of this inspection was to assess the general condition of the dams with respect to safety and, based upon these inspections and available data, determine if these dams constitute a hazard to human life or property. The Upper and Lower Lake Minnie Ha-Ha Dams are under common ownership and, for that reason, the investigation findings for both lakes are contained in this one report. The present general physical condition of both dams is considered to be somewhat less than satisfactory. Deficiencies were noticed during the inspection and are considered to have an adverse effect on the overall safety and future operation of these dams. The upstream and downstream faces of both dams supported a dense cover of high grass and/or brush that could conceal animal burrows, as well as numerous small trees. An animal burrow with consequent erosion of the embankment was noted at the toe of slope on the downstream face of the Upper Lake Minnie Ha-Ha Dam near the right abutment. Underseepage, as evidenced by soft ground, cattails and flowing water, was observed at or near the downstream toe of slope of both dams.
