AAA official bulletin
The chart published by the Puerto Rico Aqueduct and Sewer Authority, exactly as they publish it.
Bulletin for August 31, 2026
Three agencies, one bulletin
AAA publishes the bulletin but does not operate all 19 reservoirs. Six are its own, twelve are operated by the Electric Power Authority (AEE) — they are hydroelectric reservoirs — and Cerrillos is operated by the Department of Natural and Environmental Resources (DRNA). The logos across the top of the chart show which is which.
