Para hindi tayo dumating sa ganoong point, kaya nagkakaroon ng spilling operations ang mga dams natin,” she said. </p><p>The move has prompted the issuance of a flood watch by the Flood Forecasting and Warning System for Dam Operation.</p><p>PAGASA said that opening one gate of Ambuklao will affect Barangay Ambuklao in Bokod, Benguet, while the two open gates of Binga will affect Barangays Dalupirip and Tinongdan in Itogon.</p><ul class="op-related-articles">	<li><a href="https://news.abs-cbn.com/video/news/08/05/23/expert-says-bulacan-floods-not-caused-by-dam">Expert says Bulacan floods not caused by dam</a></li></ul><p>“Mayroon po minsan kasing activities doon, although mababa siya, pero &#x27;yung iba magugulat biglang mayroong mga tubig na dumarating na ganito. Para ma-warningan na &#x27;yung mga tao ay huwag na pumunta sa ilog if ever may ganitong gate operations ang mga dam.”</p><p>She added that those living in affected areas must understand that aside from open dam gates, isolated rain showers will also contribute to possible flooding.</p><p>The water level at Binga Dam may still rise in the next couple of days. Aside from isolated rain, it also catches water released by the Ambuklao Dam, while water from Binga is in turn caught by the San Roque Dam.</p><ul class="op-related-articles">	<li><a href="https://news.abs-cbn.com/news/08/02/23/nia-called-out-for-unfinished-projects-including-dam-in-tarlac">NIA called out for unfinished projects, including decades-old dam in Tarlac</a></li></ul><div><strong>ANGAT DAM WAY ABOVE RULE CURVE ELEVATION</strong></div><p>PAGASA said the inclement weather the past couple of days has contributed largely to the rise in water level of Angat Dam.</p><p>Its rule curve was at 180.79 meters, but following continuous rain, the reservoir water level is now at almost 200 meters.</p><ul class="op-related-articles">	<li><a href="https://news.abs-cbn.com/news/08/06/23/angat-dam-level-nears-200-meter-mark">Angat Dam level slightly rises, nears 200-meter mark</a></li></ul><p>Despite an almost 20-meter rise, Pagulayan said it remains difficult to predict if the level is enough to tide the public through the El Niño.</p><p>“Mahirap pong sabihin kasi we’re talking of future use. We are still on the flood season so pwede pa po itong tumaas. So maaring ma-reach natin ang 210 if ganito po &#x27;yung continuous na pag-ulan dito. Sa mga suceeding months makikita natin &#x27;yung mga pag-ulan sa watershed at masabi natin na baka pwede tayong mag last talaga until mag peak &#x27;yung El Niño,” Pagulayan said.</p><div><strong>RELATED VIDEO</strong></div><figure class="op-interactive"><iframe allow="autoplay; fullscreen" frameBorder="0" height="100%" id="ivsplayer01" scrolling="no" src="https://player.ivideosmart.com/ivsplayer/v4/dist/html/iframe-src.html?iframeid=ivsplayer01&amp;key=e8c22c015ca9eafa76f1e3edfa03c603&amp;spid=3001339&amp;vid=2743869" width="100%"></iframe></figure><div class="iwantbar">Watch more News on <a href="https://www.iwanttfc.com/#!/browse/Genres/News/tag_id_genres/id_news" target="_blank">iWantTFC</a></div>
