On Thursday, several places in Kerala were looking at a potential repeat of the devastating 2018 floods, with rivers overflowing and a series of landslides. However, the intensity of rainfall has reduced on Friday and Indian Meteorological Department (IMD) has removed red alerts from all districts. Nevertheless, parts of Central Kerala, especially in low-lying Kuttanad region, are under water.

The severity of Thursday’s situation was highlighted by the large-scale evacuation of people living on the banks of the Chalakudy river in the Thrissur district as the weather predictions suggested a large amount of water will have to be released from the Peringalkuthu reservoir, which would receive excess inflow from dams that are further upstream in Kerala and Tamil Nadu. However, the worst did not come to pass as rainfall subsided, and the river has not risen in a way that the district administration had feared.

Still, the State government is exercising caution and is preparing for controlled release of water from some of the dams to avoid any future emergencies if rainfall intensifies in their catchment areas in the next few days.

The newly installed tetrapod seawall at the coastal village Chellanam in Ernakulam district seems to be holding up well against the monsoon fury of the Arabian Sea. Chellanam residents have been battered by sea erosion, especially during monsoon rains. However, the tetrapod seawall (still under construction), which will be over 7 km long after completion, is reported to have provided much needed protection to the long-suffering residents of Chellanam.

Idukki

3 shutters of Mullaperiyar dam opened

Three shutters of the Mullaperiyar dam were raised 30 cm each as the water level in the reservoir reached 137.50ft at 1 p.m. Kerala Water Resources Minister Roshy Augustine has urged the public to exercise extreme caution.

Water levels in various rivers in the low-lying Kuttanad plains spread across Alappuzha and Kottayam districts is dangerously high and have submerged parts of the region. Several roads, including Alappuzha-Chenganasseri (AC) road, are also underwater. Moreover, thousands of hectares of paddy fields are also under the threat of inundation. Although it’s not heavily raining in Kuttanad, more inflow is expected from the upstream of the various rivers that drain into the backwaters. This extra water will have to smoothly drain out via Thanneermukkam bund and Thottappally spillway for the flood waters to recede from various parts of Kuttanad.

Chief Minister Pinarayi Vijayan have sent a letter to his Tamil Nadu counterpart M.K. Stalin seeking help to control the water level in the Mullaperiyar dam, which is in Kerala’s Idukki district, but is managed by Tamil Nadu. Mr. Vijayan’s letter comes against the dam management’s decision to raise the barrier’s spillway shutters by 12.30 p.m. on Friday, and in it he requests CM Stalin to “give directions to authorities concerned to ensure that the outflow/discharge from the dam is more than the inflow, taking into consideration the heavy rainfall in the catchment area of Mullaperiyar Dam”.

The dam will release 534 cubic feet of water in the initial phase and incrementally increase the discharge to 1000 cubic feet by 2.30 p.m.

Idukki

Three shutters of Mullaperiyar dam to be opened

As the water level have reached 136 ft in Mullaperiyar dam in Idukki district, Kerala’s Minister for Water Resources Roshy Augustine has informed that water will be released from the reservoir by raising three shutters by 30 cm at 11:30 p. m. today. This will likely increase the water level in the Idukki reservoir downstream. He informed the press that any decision to open the Idukki dam will be taken after considering the water level in the downstream areas of Periyar river that passes through some of the most populous regions in Kerala.
