¿Hay Agua?

¿Hay agua? shows you at a glance how Puerto Rico's reservoirs are

doing, with data straight from the U.S. Geological Survey (USGS).

All in one list

The island's 23 reservoirs on a single screen, each with its current

level and which way it's heading. Mark the ones you care about as

favorites and they stay at the top.

The full history

Tap any reservoir to see its level over the last 7, 30, or 90 days in

a clear chart, along with how much it has risen or fallen in the last

hour, day, week, and quarter.

Alert level

Each reservoir shows which band it falls into —Overflow, Safety,

Observation, Adjustments, Control, or Out of service— with the same

colors and thresholds published by Puerto Rico's Aqueducts and Sewers

Authority (AAA).

By reservoir name or by your municipality.

Where the data comes from

From USGS gauges, which take readings every 15 minutes. The data is

provisional and subject to revision. The app shows where the USGS

reading falls; AAA's official bulletin may report a different band,

since it measures with its own instruments.
