Due to rising reservoir levels, the Peechi Dam in Thrissur will open four spillway shutters on August 31. Residents near the Manali and Karuvannur rivers are advised to remain vigilant.

  • Four spillway shutters of Peechi Dam will open on Monday, August 31.
  • Water levels in nearby rivers may rise by up to 30 cm.
  • Residents along Manali and Karuvannur rivers are under alert.
  • Heavy rainfall is expected due to cyclonic circulation.

In response to the continuous rise in water levels following heavy rainfall in its catchment areas, the Peechi Dam in Thrissur is scheduled to open all four of its spillway shutters on Monday morning, August 31, 2026. This strategic move aims to regulate the reservoir's capacity and prevent overflow.

The scheduled release will follow a phased approach. At 11:00 AM on Monday, the shutters will be raised by two inches (5 cm). By 2:00 PM, they will be lifted by an additional two inches, bringing the total opening to four inches (10 cm). This decision has been formalized with the direct approval of the District Collector.

Hydrological Impact and Discharge

In addition to the spillway discharge, water will also be released into the Manali River through the KSEB small hydel power generation station. Meteorological experts warn that the region is likely to experience further precipitation in the coming days, driven by a low-pressure system and cyclonic circulation associated with the monsoon.

The controlled release of water is a critical preventive measure to manage reservoir pressure amidst heavy monsoon activity.

Why This Matters

BozokMedia analysis shows that such hydrological management is vital for preventing catastrophic dam failures and uncontrolled flooding. However, the rapid rise in river levels poses a direct threat to the livelihoods and safety of riparian communities.

The District Collector has issued an urgent warning to residents living along the banks of the Manali and Karuvannur rivers. Following the opening of the shutters, the water level in these rivers is projected to rise by as much as 30 cm from its current level.
