Abstract
Mathay Dam, a flood water retarding dam designed by the U.S. Department of Agriculture, Soil Conservation Service (SCS), is also known by its SCS number PA 459. The dam is a homogeneous earth embankment with a crest length of approximately 3260 feet and a maximum height of about 22 feet. The material available for construction of the dam consisted primarily of silty (ML) and silty clay (ML-CL) soils, with a lesser amount of silty sand (SM) soil. A 5-foot deep foundation cutoff trench with a base width of 15 feet was constructed along the centerline of the dam from Station 13+30 to Station 19+34. A filter trench with two drain outlets was installed in the main embankment from Station 14+94 to Station 18+41.
