Groups urge LLDA to open Napindan to deflood Laguna Lake

LAKE based groups today urged the Laguna Lake Development Authority (LLDA) to open the Napindan Hydraulic Control Structure (NHCS) to deflood the 90,000 hectare lake.

The group urged LLDA general manager Neric Acosta to open all the control panels of NHCS so the excess water from Laguna de Bay will be flushed out to Manila Bay via the Pasig River.

The groups Pambansang Lakas ng Kilusang Mamamalakaya ng Pilipinas (Pamalakaya), Save Laguna Lake Movement (SLLM) and Anakpawis party list-Laguna Lake chapter said the hydraulic control structure was constructed in the 80s to hold volumes of water deflected by Manggahan floodway to Laguna Lake and those coming from Caliraya Dam to avoid mass flooding in Metro Manila.

The groups said the control structure was never meant to control flood but to maintain there is a huge supply of water in Laguna de Bay for industrial needs and possible source of potable water ready to cater to big business interests like Maynilad and Manila Water Company.

The LLDA reported that the water level in Laguna de Bay rose to 13.6 meters above sea level Wednesday afternoon from 13.2 meters on Tuesday. The lake’s normal water level during the rainy season is 12.5 meters above sea level.

At the height of typhoon Ondoy water level in Laguna Lake rose to almost 15 meters above sea level, adding that if heavy downfall continue to batter Laguna de Bay it is not a remote possibility that Laguna Lake will reach the same level that of tropical storm Ondoy unless the LDDA orders a full-blown opening of the hydraulic control structure.

Also, at the height of typhoon Ondoy, all the fishing towns of Laguna Lake in Rizal and Laguna provinces, including several cities in the National Capital Region (NCR) were submerged under waters and it lasted for three months from October to December of 2009.

Officials of Pamalakaya, SLLM and Anakpawis party list the number of residents surrounding Laguna Lake are more or less 3.9 million people, majority of these people are small fisherfolk, lake farmers and urban poor situated along the 9 towns of Rizal, 18 towns of Laguna and cities of Taguig, Muntinlupa and municipality of Pateros.

Reports reaching the groups revealed that the fishing towns of Binangonan, Angono and Taytay and several barangays in Talim Island divided by boundaries of Cardona and Binangonan towns are flooded due to overflowed Laguna Lake.
