The present Lake Hauto Dam was constructed from 1912 to 1914 and replaced a smaller dam located 350 feet upstream. The dam was designed by the Engineering Department of the American Pipe and Construction Company. Its Chief Engineer, J. W. Ledoux, made periodic inspection trips during construction, besides having a resident engineer engaged during the entire time of construction. The Contractor was McNichol Paving and Construction Company, Philadelphia. The dam was constructed for the Lehigh Coal and Navigation Company. The reservoir water was used as cooling water for a steam electric plant located south of the dam and for commercial water supply for collieries and washeries. The consulting firm Gannett, Seelye and Fleming, Inc., Harrsiburg, designed a two-foot high addition to the dam and an enlargement of the spillway capacity by widening the spillway. The spillway crest was also raised two feet. A suspension bridge was located across the spillway. PennDER objected to the low under-clearance of this bridge and requested a replacement to prevent possible clogging up of the spillway. A drawing, dated 1920, indicates details of the present bridge supported on bent mine rails and presumably this bridge was extended in 1923 when the spillway was enlarged from 70 feet to 100 feet. The files did not contain an application or a permit for the construction of the bridge. In 1963 major repairs were made to the concrete weir and upstream part of the spillway slab and walls. Author
