National Dam Safety Program. Newman Lake Dam (MO 30488), Mississippi - Kaskaskia - St. Louis Basin, Madison County, Missouri. Phase I Inspection Report
Newman Lake Dam is classified as a small earth dam, based on its height of approximately 25 ft and storage capacity of 140 ac-ft. The small dam classification criteria are: height between 25 and 40 ft, or storage capacity between 50 and 1000 ac-ft. The St. Louis District (SLD), Corps of Engineers, has classified this dam as having a high hazard potential. The SLD estimated damage zone length extends approximately 4 mi downstream. Within this estimated damage zone are several dwellings, a church, an electric transmission line, and a buried petroleum pipeline. The contents of the damage zone were verified by aerial reconnaissance. Based on the findings of the visual inspection and analysis of other data, the dam appears to be in generally fair condition. No evidence was noted of disruption of the vertical or horizontal alignment of the dam crest, sinkhole development, cracking, slumping or animal burrows. The downstream slope is considered to be quite steep, on the order of 1.5(H) to 1(V) at the maximum section. Some wave erosion has occurred along the upstream slope. Trees growing on the downstream slope, some of which have been cut down, are considered a deficiency. Seepage and stability analyses for this dam comparable to the 'Recommended Guidelines for Safety Inspection of Dams' are not on record, which is also considered a deficiency.
