USGS National Water Dashboard
Tablero de Recursos Hídricos Nacionales
The USGS monitors and studies water resources to deliver a wide range of data including streamflow conditions, groundwater information, lake and reservoir elevation, water quality, water use, and water availability, which can be accessed through the USGS National Water Dashboard. As of 2022, the USGS real-time water data network is comprised of 109 streamflow observation stations, 20 groundwater stations (3 in U.S. Virgin Islands), 27 lake and reservoir elevation stations, and 3 continuous water quality stations. The USGS also maintains a periodic data collection network of 51 water quality sampling sites and 30 groundwater level sites. The USGS maintains these stations to produce real-time information to end users. Hydrologic technicians perform damage assessment and take corrective actions to restore the network after storms. The Water Resources Mission Area has also created water-use and flood reports of Puerto Rico. On this page, Explore news and information related to water resources in Puerto Rico including data from the real time and periodic networks, flood reports, and water use.
El USGS vigila y estudia los recursos hídricos para ofrecer una amplia gama de datos que incluyen las condiciones de los caudales de agua, información sobre las aguas subterráneas, la elevación de los lagos y embalses, la calidad del agua, el uso del agua y la disponibilidad del agua. Todos estos datos se pueden acceder mediante el National Water Dashboard (Tablero de Recursos Hídricos Nacionales). Hasta el 2022, la red de datos de agua en tiempo real del USGS se compone de 109 estaciones que miden el flujo del agua; 20 estaciones de aguas subterráneas (3 en las Islas Vírgenes de los Estados Unidos); 27 estaciones de elevación de agua en lagos y embalses; y 3 estaciones de calidad de agua. El USGS también mantiene una red de recolección de datos periódicos compuesta por 51 estaciones de muestreo de calidad y 30 estaciones de nivel freático. El USGS mantiene estas estaciones para proporcionar información en tiempo real a los usuarios. Los técnicos hidrológicos realizan una evaluación de daños y toman las medidas necesarias para restablecer la red luego de tormentas.

Water Withdrawals and Use | La extracción de agua y sus usos
USGS researchers have provided water use data for Puerto Rico since 1980 to help planners and managers with information to adequately assess water resources. Five major categories are considered: public-supply water withdrawals and deliveries, domestic and industrial self-supplied water use, crop-irrigation water use, and thermoelectric-power freshwater use. Access the latest report on water withdrawals and water use in Puerto Rico for 2015 here.
Los investigadores del USGS han provisto datos del uso de agua en Puerto Rico desde 1980 para que los planificadores y administradores puedan contar con la información necesaria para evaluar adecuadamente los recursos de agua. Los reportes consideran cinco categorías principales: las extracciones y provisiones hídricas del suministro público, el uso hídrico doméstico e industrial de abastecimiento propio, el uso hídrico para la irrigación de cultivos y al uso de agua dulce para la energía termoeléctrica.

Puerto Rico Natural Hazards | Peligros naturales de Puerto Rico
The island of Puerto Rico is subject to numerous threats from natural hazards, including hurricanes, landslides, earthquakes, tsunamis, coastal and inland flooding, environmental contaminants, and freshwater scarcity, among others. USGS science can help citizens better prepare for, mitigate, and adapt to these hazards. This website compiles USGS resources available for Puerto Rico to provide...Water Quality for Puerto Rico
The U.S. Geological Survey operates and maintains approximately 7,300 streamgages nationwide, 194 in Puerto Rico, which provide long-term, accurate, and unbiased information that meets the needs of many diverse users. The USGS collects the streamflow data needed by Federal, State, and local agencies for planning and operating water-resources projects and regulatory programs. The links below allow...Sedimentation Surveys in Puerto Rico
Reservoirs provide most of the water supply for Puerto Rico. Most of them were constructed in the early and middle 20th century and sediment accumulation has significantly reduced their original storage capacity. The U.S. Geological Survey (USGS) has been conducting a series of bathymetric surveys using a global positioning system (GPS) and a geographic information system (GIS) technology on the...Water-Use in Puerto Rico
The National Water-Use Information Program of the U.S. Geological Survey (USGS) is a cooperative program designed to compile, store, and disseminate water-use information locally and nationwide. Since 1950, the USGS has compiled data at 5-year intervals on amounts of water used in homes, businesses, and on farms in the United States, and has described how that use changed with time.Climate of Puerto Rico
In general, the east-west trending Cordillera Central and Sierra de Cayey mountains form an insular hydrologic divide that separates the island of Puerto Rico into two climatologically distinct regions. The northern two-thirds of the island has a relatively humid climate whereas the southern one-third of the island is semi-arid. - Maps
