Emergency Action Plan for Krishnarajasagara Dam KA06HH0020 Water Resources Department State of Karnataka. EMERGENCY ACTION PLAN OF KRISHNARAJASAGARA DAM [KA06HH0020] Prepared for Karnataka Water Resources Department (Cauvery Neeravari Nigam Limited) Prepared by Chief Engineer, Irrigation South Zone, Mysuru. Emergency Action Plan for KRISHNARAJASAGARA (KRS) DAM [KA06HH0020] version 2.0 KRISHNARAJASAGARA DAM Project ID Code [KA06HH0020] Mandya, Karnataka DISCLAIMER Every effort has been taken to estimate the severity of flooding and inundation areas likely to be affected by Krishnarajasagara Dam in an emergency condition. These estimates are based on available primary and secondary data. Every effort has been made to foresee varied emergency possibilities and develop appropriate notification procedures for timely rescue and relief operations. However, implementation of the Emergency Action Plan (EAP) involves many agencies, who are required to work in a coordinated manner to reduce the consequences of the emergency triggered by the dam site condition. Effectiveness of the rescue and relief operations depend on many factors including the adequacy and accuracy of the estimation of the severity of flooding, coordinated efforts of all the agencies involved in rescue and relief efforts and availability of facilities like power, telephones, road communications, etc. EAP developer may therefore, not be held responsible for the efficacy of the EAP.
