The director of the Arecibo Zone of the Bureau for Emergency Management and Disaster Administration (Nmead), Juan Santos, indicated that are vigilant to the overflow in Lake Dos Bocas because it could flood areas of the urban center of Arecibo.
Santos indicated that, at the moment, it is not necessary to carry out evictions of residents, but that they would be prepared to carry them out if necessary together with the Office of Emergency Management (Omme) of the Municipality of Arecibo.
The waters that overflow the Dos Bocas lake discharge to the Grande de Arecibo river that empties into the urban area of Villa del Capitán Correa. If the overflow is severe, it can flood La Puntilla, the Rodríguez Olmo community, the Martel urbanization, and several streets in the urban center.
The director of dams and reservoirs of the Electric Power Authority (PREPA), José Bermúdez, said that Dos Bocas is overflowing and that its design has no gates to control the amount of accumulated water.
“Anything that comes in excess is going to go through the spillway,” said the PREPA official.
Dos Bocas is a gravity dam with a spillway to handle the overflow, that is, to discharge what exceeds the top of that spillway.
“All the basins are active and This means that all the water that is falling into the basins is reaching the reservoirs. Right now everyone is loading water, many near the overflow and others overflowing, “said Bermúdez.
Dos Bocas is part of the northern basin that is made up of four dams and is an interconnected system that receives a lot of water, explained the director of dams and reservoirs. Dos Bocas is the last dam in that system.
According to data from the United States Geological Survey (USGS), the dam exceeded its storage capacity by two feet. The federal agency, through a collaborative agreement with PREPA, has measurement instruments in the reservoirs that allow viewing graphs in real-time.
