Abstract:

The Clarks Creek Watershed Project Site I dam consists of an earth dam with a service spillway pipe passing through the embankment and an excavated auxiliary spillway passing around the eastern end of the dam. The dam consists of a compacted earth embankment which is 46 feet high, has a crest length of 1250 feet and a crest width of 16 feet. The upstream slope is 1 vertical on 3 horizontal with a 10 foot wide berm near the base of the slope. The downstream slope is 1 vertical on 2.5 horizontal. The crest and exposed slopes are covered with grass and crownvetch. An earth cutoff trench of varying depth and width keys the embankment into the foundation soils. The examination of documents and visual inspection of the Clarks Creek Site 1 Dam did not reveal conditions which constitute a hazard to human life or property. The total discharge capacity of the spillways is adequate to impound and safely discharge the floodwaters resulting from the Probable Maximum Flood PMF.
