The Puerto Rico Water Authority reported on Friday that 13 of the 19 daily monitored reservoirs recorded decreases in water levels. [^1]

The Autoridad de Acueductos y Alcantarillados (AAA) confirmed that 14 of the 19 monitored reservoirs in Puerto Rico recorded declines in water levels as of 5:00 a.m. on August 20, 2026. [^3] An estimated 3,063,519 people live in zones affected by some level of drought across Puerto Rico. [^2]

For the first time since late June, none of the 19 monitored reservoirs in Puerto Rico are in the flood stage category. [^4] The read here is that the island has shifted from flood concerns to widespread water shortages, though the facts do not specify the speed or severity of that transition. [^3]
