13 shutters on the spillway will be raised by 10 centimeters each. Initially, 250 cubic feet of water will be released per second.
Idukki, June 29: Due to continuous heavy rainfall in the catchment areas, the water level at the Mullaperiyar dam has risen to 136.20 feet, prompting authorities to begin the controlled release of water. The dam will be opened at 12 PM, and 13 shutters on the spillway will be raised by 10 centimeters each.
Initially, 250 cubic feet of water per second (cusecs) will be released.
The increased inflow is a result of intensified rainfall in the Periyar Tiger Reserve, which forms the dam's catchment area. Once the dam is opened, the released water will flow through the Periyar River and eventually reach the Idukki reservoir.

Public safety measures and advisory
The Idukki District Collector has assured the public that there is no cause for alarm, but issued a set of safety guidelines for residents living near the riverbanks:
- Residents in homes close to the Periyar river that are prone to flooding should consider relocating to relatives' homes as a precaution.
2. Arrangements have been made for relocation to relief camps if needed.
3. A total of 20 relief camps will be set up across the affected region.
4. If the dam reaches maximum water release, approximately 3,200 people from 883 families may be impacted.
5. Bathing, washing, or entering the river while the spillway shutters are open is strictly discouraged.
6. Crossing the Periyar river should be avoided during the water release.
7. Residents living along the riverbanks need not panic, as no immediate danger is expected.
