Revisiting the Marikina mega dike project along Marikina River

The Marikina mega dike project along Marikina River has been ongoing for several years, with various phases and updates throughout its construction.  

Here's a summary of the latest information:


Progress:
Phase 3: As of 2020, Phase 3 of the project was completed, which included dredging the Manggahan floodway to increase its flood capacity.

Ongoing work: The project is still ongoing, with construction continuing on different sections of the dike.

Revised design: The original design of the road dike project has been revised and is now called the Riverside Development, which involves raising the elevation of some areas and constructing drainage outfalls.

The Marikina mega dike project is progressing, with various phases completed and ongoing work. The project aims to mitigate flooding in the Marikina area

In the meantime, the Pasig-Marikina River Channel Improvement Project - Phase IV, which includes building the Marikina Control Gate Structure, and the Metro Manila Flood Management Project, involve building and enhancing pumping stations along vital waterways.

Senior Undersecretary Sadain stated that in order to ensure safe flow of the remaining floodwaters through Metro Manila without causing significant flooding, two additional proposed projects are an Upper Marikina Dam, located approximately four (4) kilometers upstream from the current Wawa Dam in Montalban Gorge, and a retarding basin, located downstream of the Marikina River Basin. These projects are intended to help reduce peak river flows entering Metro Manila during typhoons and extreme rainfall.

Floating Crane Spotted Drifting in Marikina River

Last August 13, 2016, around 2:30pm, a crane on a barge was dislodged from the Marikina River banks and floated along the Marikina River. A portion bumped into the pillars beneath the Marikina Bridge as it floated underneath the bridge.  On the floating device was 19 year old Romeo Laguna, who was able to jump away from the barge and was rescued by Marikina City personnel before the crane eventually sunk when it collided with the Marcos Bridge, Marcos Highway.

According to Marikina Mayor Marcy Teodoro, the crane was situated by the side of Marikina River which was currently used for dredging and piledriving by the riverside for slope protection. Unfortunately, the water level rose at quick rate, unlocking the floating device and crane from its position.

Due to continuous rains brought by Habagat, the water level reached 18.6 meters around 6pm. Eight floodgates were opened to lower the water level. By 9:45pm, water level receded to 17.5 meters.

According to Panahon.tv, as of August 15, 9:00am, water level has receded to 14.8 meters and all flood alerts have been lifted. However, classes in all levels have been suspended for Marikina.

 Here are some news report situationer updates on Marikina River and the weather.

Addendum: This is the not the first time large man-made objects floated and crashed into the bridges in Marikina. In 2012, a floating stage also crashed into the bridge causing it to be schredded into pieces.
