Book Description
The Dam is an earthfill structure about 1000 feet long and 23.3 feet high with a gravel roadway traversing the entire dam. The dam is classified as small on the basis of size, and given a hazard classification of significant on the basis of downstream area development. The principal spillway consists of a 42-inch diameter corrugated metal pipe (CMP) vertical riser connected to a 36-inch diameter CMP which passes through the dam at a low level. The emergency spillway is an open earth channel cut in the left abutment. The spillways will pass 10 percent of the PMF or 20 percent of the SDF without overtopping the crest of the dam. The spillway is adjudged inadequate but not seriously inadequate. The visual inspection revealed that there are no immediate needs for remedial measures, except for the monitoring of the spring beneath the primary spillway outlet. It is recommended that a regular maintenance and operations program be instituted with provisions for accurate records of all maintenance performed.

Book Description
Pursuant to Public Law 92-367, Phase I Inspection Reports are prepared under guidance contained in the recommended guidelines for safety inspection of dams, published by the Office of Chief of Engineers, Washington, D.C. 20314. The purpose of a Phase I investigation is to identify expeditiously those dams which may pose hazards to human life or property. The assessment of the general conditions of the dam is based upon available data and visual inspections. Detailed investigation and analyses involving topographic mapping, subsurface investigations, testing, and detailed computational evaluations are beyond the scope of a Phase I investigation; however, the investigation is intended to identify any need for such studies. Based upon the field conditions at the time of the field inspection and all available engineering data, the Phase I report addresses the hydraulic, hydrologic, geologic, geotechnic, and structural aspects of the dam. The engineering techniques employed give a reasonably accurate assessment of the conditions of the dam. It should be realized that certain engineering aspects cannot be fully analyzed during a Phase I inspection. Assessment and remedial measures in the report include the requirements of additional indepth study when necessary.

Book Description
The dam is an earthfill structure about 800 feet long and 45.2 feet high. The dam is classified as an intermediate size dam with a significant hazard classification. The designed principal spillway is a 10-inch steel drop-inlet stand pipe located in the reservoir. Because of underlying cavernous limestone beneath the reservoir, the water level is considerably below the normal design pool. There are two emergency spillways. The left emergency spillway is an open channel spillway which is a low point in natural ground. The right emergency spillway is an open channel cut into natural ground. The spillways will pass the PMF without overtopping; therefore, the spillways are adjudged as adequate. The visual inspection revealed no apparent problems or remedial measures in need of immediate attention.
