Interactive Maps

Depth-to-water is measured periodically to evaluate hydrologic conditions at important aquifers throughout Puerto Rico. The water-level measurements from observation wells can be computed to understand the hydrologic stresses acting on aquifers and how these stresses affect groundwater conditions.

Both the GOA Dashboard and the Sea-level Tool feature interactive maps for viewing either water data and associated weather data or the potential for flooding. Both maps are specific to regions along the Gulf of America.

The Biomonitoring of Environmental Status and Trends (BEST) Program's Large River Monitoring Network (LRMN) has examined fish health in multiple river basins by using a suite of organismal and suborganismal endpoints, which monitor and assess the effects of environmental contaminants in fish.

This site provides hydrologic data collected or compiled by the USGS in the Yucaipa area; some additional data may be available from the USGS database National Water Information System (NWIS).

The Geologic CO2 Sequestration interactive web map includes investigated basins, assessed areas, stratigraphic columns, and well density information.

The following graphs show water surface elevations above NGVD 1929 in selected reservoirs for several years, including 2015. The purpose of these graphs is to compare water surface elevations during 2015 with water surface elevations observed during years when documented droughts have occurred.
