Kerala Precautionary Dam Release: Residents Along Periyar Advised Caution

The district administration of Idukki in Kerala permitted the opening of shutters of the Pambla dam on Saturday, July 4, 2026, as a precautionary measure following heavy rainfall in the catchment areas. The dam, operated by the Kerala State Electricity Board (KSEB) for hydroelectric power generation, was allowed to discharge up to 500 cubic metres per second (cumecs) of water starting from 10 am, according to an official order issued by the District Collector.

Officials said the water level in the reservoir had risen to 251.70 metres due to continuous rainfall, prompting the executive engineer to seek permission to regulate the inflow. The maximum permissible water level of the dam is 253 metres. The decision to release water was taken in view of the heavy rainfall forecast for the district and in accordance with the dam safety and disaster management guidelines.

Authorities directed dam operators to implement all precautionary measures prescribed under the Disaster Response Guidelines before releasing water. Residents living along both banks of the Periyar River have been advised to exercise caution, while officials have been directed to take all necessary safety and precautionary measures. The district administration has also alerted local authorities to monitor the situation closely and ensure preparedness for any emergency.

The Pambla dam is one of the key hydroelectric projects in Idukki, and its operation follows strict protocols to balance power generation and flood safety. The current release is a standard precautionary step to prevent the reservoir from exceeding its maximum capacity, which could pose a risk during continuing rains. This measure reflects the state's commitment to disaster risk reduction and public safety.
