<br />Condition Index Scales <br /> <br />C <br /> <br />Condition Descri tion <br />Satisfactory: The safety inspection indicates no conditions that <br />appear to threaten the safety ofthe dam and the dam is expected to <br />rform satisfactoril under all desi loadin conditions. <br />Conditionally Satisfactory: The safety inspection indicates <br />symptoms of structural distress (seepage, evidence of major <br />displacements, etc,) that, if conditions worsen, could lead to failure <br />of the dam, Essential monitoring, inspection, and maintenance must <br />be erformed as a re uirement for continued full stora e, <br />Unsatisfactory: The safety inspection indicates definite signs of <br />hydrologic inadequacy or structural distress (excessive seepage, <br />cracks, slides, sinkholes, severe deterioration, etc,) that could lead <br />to failure of the dam if 0 erated at full stora e, <br /> <br />Grade <br />AorB <br /> <br />D <br /> <br />Criterion 2: Need versus Capacity (Manpower and Assets) <br /> <br />This criterion, as defined by the advisory board, pertains to the adequacy of the dam safety <br />programs that operate in Colorado. <br /> <br />With regard to dam safety programs, the "need" is for adequate dam safety inspections, <br />monitoring, record keeping, and emergency preparedness plans at federal, state, and local levels, <br />The advisory board attempted to define a "grade" for the dam safety programs that considers the <br />technical adequacy ofthe programs, and their current capacity in regard to manpower and assets <br />such as number of inspectors and support staff, available tools, and possibly other considerations, <br /> <br />Criterion 3: Funding versus Need <br /> <br />The advisory board chose to define this criterion on the basis of funding needed for dam <br />rehabilitation to bring deficient facilities up to current dam safety standards. <br /> <br />2.5.3 Composite Grades - Only high hazard, or Class 1, dams were considered in the <br />condition index evaluation. By the Colorado Division of Water Resources, a Class I dam is a <br />dam for which loss of human life is expected in the event of failure, <br /> <br />Composite grades were developed by each of the three agencies for high hazard dams under their <br />jurisdiction: (I) Colorado Division of Water Resources (includes state, local governments, <br />private, utilities, and some federal dam owners), (2) Department of the Interior (includes dams <br />owned and operated by U.S. Bureau of Reclamation and U.S. Forest Service), (3) U.S. Army <br />Corps of Engineers dams. The following point scale was assigned to compute the grades: A=4, <br />B=3, C=2, 0=1, F=O, - <br /> <br />Once composite grades for dams from each agency were developed, a weighted average grade <br />for all dams based on number of dams under each sector in the high hazard (Class I) <br />classification was computed, The overall composite grade for Colorado dam safety was <br /> <br />5 <br />
