Three major dams in Luzon, one of which is still above its high water level, kept their gates open Monday morning to let out excess water.

PAGASA said that as of 6 a.m. Monday, Ambuklao kept one gate open, while Binga and San Roque each kept two gates open.

Ambuklao is located in Bokod town in Benguet while Binga is in Itogon town also in Benguet. San Roque spans San Manuel and San Nicolas in Pangasinan, and extends to Itogon, Benguet.

Last week, several dams in Luzon kept their gates open amid heavy rain brought by Tropical Storm Helen (Kai-Tak).

Ambuklao's water level as of 6 a.m. Monday was at 750.98 meters, down slightly from 751.71 meters Sunday morning. It was below the 752-meter high water level

Binga kept two gates open as its water level stood at 574.35 meters, slightly below Sunday's water level of 574.50 meters. This was below the high level of 575 meters.

However, San Roque, which kept two gates open, had water levels of 281.33 meters, higher than the 280.78 meters recorded Sunday.

San Roque's water level for Monday was also above its high level of 280 meters. — RSJ, GMA News
