The Main Report generally summarizes data found in the Appendices and utilizes suitable plates originally presented in Appendix A. Appendix B (Emergency Identification Subplan) describes procedures and means for assuring reliable identification and evaluation of potential, impending and existing emergency situations, affecting the operation and safety of the dam, related to the two failure conditions, the SDF/PMF without dam failure, and sabotage to project features. Appendix C (Emergency Operations and Repair Subplan) specifies the emergency operations to be implemented and repairs to be considered upon 'flood warning condition'and 'emergency condition' declarations for cases of high reservoir level, excess seepage/internal drainage system malfunction, spillway discharges and dam failure. Appendix D (Notification Subplan) specifies notifications and other actions upon 'flood warning condition' and 'emergency condition' declarations, coordinated among the Corps of Engineers, National Weather Service, and state and local agencies.
