National Dam Safety Program. Tamarack Dam (MO 30452), Mississippi - Kaskaskia - St. Louis Basin, Jefferson County. Phase I Inspection Report
The purpose of the inspection was to make an assessment of the general condition of the dam with respect to safety, based upon available data and visual inspection to determine if the dam poses hazards to human life or property. The inspection and evaluation indicates that the dam is deficient in that the spillways do not meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. Considering the volume of water impounded, the floodplain downstream and potential residential development downstream, the Probable Maximum Flood (PMF) is the appropriate spillway design flood. The probable maximum flood is defined as the flood discharge that may be expected from the most severe combination of critical meteorological and hydrologic conditions reasonably possible in the region. The dam will begin to be overtopped by a flood having a discharge (peak and volume) equal to 50% of the PMF. The spillways will pass 1% chance flood (100-year flood) without overtopping, which is a flood that has a 1% chance of being equalled or exceeded in any given year. There were indications of seepage or underseepage through or under the dam embankment. This is a serious safety deficiency which could lead to failure of the embankment.
