Embalses de Puerto Rico, lectura por lectura
A bilingual dashboard tracks the water levels of Puerto Rico’s 19 reservoirs using USGS sensor readings and the AAA’s daily bulletin.
Field notes
The dashboard separates the freshest sensor reading from the fixed 5:00 a.m. AST reading used for day-to-day comparisons, avoiding misleading comparisons between different times of day. USGS sensors measure every 15 minutes and transmit in hourly batches, while the site retains those measurements and presents coverage across all 19 reservoirs. Individual cards include operating labels such as Safety, Operational Adjustments, and Observation.
