The Carraízo reservoir level decreased by 8 centimeters to 39.01 meters, remaining within the 'observation' level set by the Autoridad de Acueductos y Alcantarillados (AAA). This decrease follows a significant increase in the reservoir’s level due to recent rainfall. The 'observation' threshold for Carraízo is 38.50 meters, so it remains 51 centimeters above this mark.

Other reservoirs also experienced changes, with 13 out of 19 monitored reservoirs registering decreases, 5 increases, and 1 remaining unchanged. Notable decreases include Río Blanco, which lost 4 centimeters to 24.85 meters, and Fajardo, which decreased by 5 centimeters to 46.69 meters. The largest decrease was in Dos Bocas, which lost 26 centimeters to 89.70 meters.

In contrast, 5 reservoirs registered increases, with Loco experiencing the largest increase of 10 centimeters to 69.56 meters. The AAA continues to monitor the reservoir levels, with some reservoirs still above the 'observation' or 'operational adjustments’ thresholds.
