Examination of documents and visual inspection of Inghams Dam and appurtenant structures did not reveal conditions which would constitute a hazard to life or property. The dam has a number of problem areas which require further investigation and remedial action. These areas include: (1) Additional hydrologic investigations are required to more accurately determine the site specific characteristics of the watershed. It has been determined that the spillway embankment would be overtopped for all storms exceeding approximately 24% of the Probable Maximum Flood (PMF) spillway capacity = 21,000 cfs. The spillway is adjudged as 'seriously inadequate' and the dam is assessed as unsafe, non-emergency; (2) The stability analysis conducted in 1970 did not include the condition of ice loading pressures on the dam. Additional investigation is required to determine the type and extent of remedial action required; (3) The reservoir drain has not been operated since completion of the dam. The drain should be investigated and returned to operating condition; and (4) An inspection of the spillway should be conducted during no flow conditions to assess the integrity of the spillway.
