Abstract:

Based on available records, past operational performance, visual inspections and Phase I engineering analysis, Cooks Pond Dam is assessed as being in fair overall condition. Based on investigations of the downstream flood plain made in connection with this report, it is recommended that the hazard potential classification be downgraded from high to significant hazard. The spillway is capable of passing the designated spillway design flood 100-year storm without an overtopping of the dam and, therefore, is assessed as being adequate. It is recommended that the following remedial measures be undertaken by the owner in the future 1 The spillway discharge chamber and discharge channel should be cleaned of debris. 2 Soil on the downstream side of the embankment should be properly graded, compacted and stabilized. 3 Trees and adverse vegetation on the embankment should be removed. 4 Deteriorated stoplogs should be replaced. 5 Riprap on the upstream side of dam should be renovated. 6 The crest of dam should be properly stabilized.
