The Aqueduct and Sewer Authority (AAA) reported today, Wednesday, that the Carraízo reservoir entered the control level with 37.12 meters, while the Cidra reservoir descended to the level of operational adjustments and accumulates 400.99 meters of water.
The level of control for any reservoir implies that the AAA must implement a service interruption plan to extend the life of the body of water. Meanwhile, the operational adjustment phase means that the public corporation must take preventive measures to avoid an abrupt and continuous decrease in the level of the reservoir in question.
However, one of the main problems of the Carraízo reservoir and that of Cidra is that both are in the eastern-inland area of the island where not enough rain has fallen and neither is an episode of vigorous expected in the next few days, according to weather models.
For example, the meteorologist from National Meteorological Service Fernanda Ramos announced that the arrival of a tropical wave with the potential to produce rains and thunderstorms is expected tomorrow, but it is not clear whether it will have a positive effect on the reservoirs.
“The tropical wave itself It has an area with enough humidity, but we have to see if that area reaches our area and provides us with persistent activity that leaves accumulations of water. However, we should not be depending on whether this wave will take us out of the drought or increase the level of reservoirs, because this type of rain event must occur for several days in order to achieve this, "said the expert.
For Carraízo or any of the reservoirs under observation to improve their condition, according to the meteorological agency, a large atmospheric system must arrive with the capacity to generate more than five inches of water accumulations. Only in this way could runoff be generated that reaches the reservoir basin and then increases its level.
Much of the island, from the south to the north, accumulates a precipitation deficit of between eight to 12 inches. However, for the east-interior area, where the Carraízo basin is located, the deficit is around 12 to 16 inches.
The term rain deficit refers to the amount of precipitation that a territory does not receive in a certain time and in the case of Puerto Rico the period exceeds 60 days.
From yesterday to today only four reservoirs saw an increase in their level: Patillas, Río Blanco, Caonillas and Fajardo. Meanwhile, the Cerrillos reservoir was the only one that did not reflect changes in its supplies.
Currently, five reservoirs are kept under observation: Patillas that has 61.79 meters of water, Toa Vaca (147.53), Carite (541.82) , Guajataca (193.64) and Cerrillos (157.98).
