¿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.…

Each store’s release notes, as the developer wrote them. They are the developer’s words, not ours.
Made-to-measure settings, and real iPad support. • The app is now universal: on iPad you see the list and the details side by side, in portrait and landscape. • New Settings screen: – Pick your unit: feet or meters. – Pick your reference: above sea level (as the USGS reports it) or depth of the water at the dam. – Pick the app's language, independent from the device's.

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
