摘要

Examination of documents and the visual inspection of Mariaville Lake Dam did not reveal conditions which would constitute an immediate hazard to human life or property. However, the dam has some deficiencies which require further investigation and remedial action. Using the Corps of Engineers' 'screening criteria' for the initial review of spillway adequacy, it has been determined that the embankment would be overtopped for all storms in excess of 10% of the Probable Maximum Flood (PMF). The spillway is, therefore, adjudged as 'seriously inadequate' and the dam is assessed as unsafe, non-emergency. The classification of 'unsafe' applied to a dam because of a 'seriously inadequate' spillway means that there appears to be a serious deficiency in spillway capacity and if a severe storm were to occur, over-topping and failure of the dam could take place, significantly increasing the hazard to loss of life downstream of the dam. It is recommended that within 3 months of notification to the owner, detailed hydrological/hydraulic investigations of the structure should be undertaken to more accurately determine the site specific characteristics of the watershed and their effect upon the overtopping potential of the dam. Seepage found in and around the spillway during the inspection was of major concern.
