National Dam Inspection Program. Butler's Lake Dam (NDI Number PA-01067, PennDER Number 2-29) Ohio River Basin, Drennen Branch, Allegheny County, Pennsylvania. Phase I Inspection Report.
Abstract
The purpose of the investigation is to make a determination on whether or not the dam constitutes a hazard to human life or property. Butler's Lake Dam is classified as a 'high' hazard dam. Butler's Lake Dam is owned by Butler's Golf Course, Elizabeth, Pennsylvania 15037. The field inspection of the Butler's Lake Dam was performed on 11 December 1980, and consisted of: Visual observations of the embankment crest and slopes, groins and abutments; Visual observations of the principal (and emergency) spillway including approach and discharge channels and overflow crest; Visual observations of portions of the outlet works intake structure and conduit; Visual observations of the embankment's downstream toe area including drainage channels and surficial conditions; Visual observations of the reservoir shoreline, inlet stream channel, and watershed; Visual observations of downstream conditions and evaluation of the downstream hazard potential; Transit stadia surveys of relative elevations along the embankment crest centerline, spillway, and across the embankment slopes. The visual observations were made during periods when the reservoir was at normal operating level. There was no defined tailwater.
