<br />Final Determination of Hazard Rating <br /> <br /> <br />The final step is assignment of the hazard classification. Information from <br /> <br /> <br />Step 3 is used, and the definition of hazard ratings as developed by the <br /> <br /> <br />Bureau of Reclamation. [5] <br /> <br />Hazard classifications are defined as follows: <br /> <br />Classification <br /> <br />Abbreviated <br /> <br />Low Hazard <br /> <br />L <br /> <br />Description <br />Failure would cause only loss of <br /> <br />the dam itself with little <br /> <br />additional damage to property <br /> <br />and project operation. <br /> <br />Moderate Hazard <br /> <br />M <br /> <br />Failure would cause great damage <br /> <br />to property and project <br /> <br />operation, but loss of human <br /> <br />life is not envisioned, <br /> <br />High Hazard <br /> <br />H <br /> <br />Failure of structure would <br /> <br />result in probable loss of human <br /> <br />life. <br /> <br />The State Engineer's Office uses additional generalized criteria which relate <br /> <br /> <br />depth and velocity of flow at the various critical sections (Step 3) to hazard <br /> <br />classification. These are described as follows: <br /> <br />20 <br />
