At a glance

  • La Plata reservoir lost 8 centimeters of water between Saturday and Sunday
  • Other reservoirs, including Carraízo and Matrullas, also registered decreases in their water levels
  • The El Niño phenomenon may be contributing to the decreases in water levels

Why this matters: The water level decreases in Puerto Rico’s reservoirs, particularly La Plata, may impact the island’s water supply and increase the risk of drought, affecting local households and communities.

Puerto Rico’s La Plata reservoir dropped 8 centimeters between Saturday and Sunday, falling from 44.47 meters to 44.39 meters, according to a graphic published by the Puerto Rico Aqueduct and Sewer Authority (AAA). It is the only reservoir remaining below its adjustment level, and had already lost 9 centimeters between Friday and Saturday.

Matrullas, in Orocovis, saw one of the largest declines, losing 17 centimeters to reach 734.47 meters.
