The condition of a dam is categorized into one of the following <br />classifications: <br />• Satisfactory - No existing or potential dam safety deficiencies are recognized. Acceptable <br />performance is expected under all loading conditions (static, hydrologic, seismic) in accordance <br />with the applicable regulatory criteria ortolerable risk guidelines. <br />• Fair - No existing dam safety deficiencies are recognized for normal loading conditions. Rare or <br />extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in <br />the range to take further action. <br />• Poor - A dam safety deficiency is recognized for loading conditions which may realistically <br />occur. Remedial action is necessary. "Poor" may also be used when uncertainties exist as to <br />critical analysis parameters which identify a potential dam safety deficiency. Further <br />investigations and studies are necessary. <br />• Unsatisfactory - A dam safety deficiency is recognized that requires immediate or emergency <br />remedial action for problem resolution. <br />Page Igo <br />
