National water summary 1987: Hydrologic events and water supply and use
Water use in the United States, as measured by freshwater withdrawals in 1985, averaged 338,000 Mgal/d (million gallons per day), which is enough water to cover the 48 conterminous States to a depth of about 2.4 inches. Only 92,300 Mgal/d, or 27.3 percent of the water withdrawn, was consumptive use and thus lost to immediate further use; the...

Coffman, Jerry L.; von Hake, Carl A.; Stover, Carl W.; Coffman, Jerry L.; Von Hake, Carl A.; Stover, Carl W. New seismic study begins in Puerto Rico
A new seismological project is now underway in Puerto Rico to provide information needed for accurate assessment of the island's seismic hazard. The project should also help to increase understanding of the tectonics and geologic evolution of the Caribbean region. The Puerto Rico Seismic Program is being conducted by the Geological Survey with...

Due to an unprecedented decision by the U.S. Geological Survey representative in Puerto Rico, two USGS employees in Guaynabo have actually moved to the city’s civil defense facility and will remain there until the latest in a series of hurricanes (Jose) no longer appears to threaten the lives and property of the residents of Puerto Rico and the Virgin Islands.
Today, as Hurricane Jose was upgraded from a tropical storm, the U. S. Geological Survey in Puerto Rico was monitoring the storm’s path and intensity very closely. If the hurricane threatens Puerto Rico later this week, as predicted, the USGS is prepared to provide critical information to local government and emergency management officials responsible for protecting the lives and property of Puert
USGS scientists from the Patuxent Wildlife Research Center, the National Wetlands Research Center and the Florida and Caribbean Science Center are gearing up to assess Hurricane Floyd damage to wildlife and habitat from Florida to Maine.
Hurricane Georges approached Puerto Rico on September 21, 1998 as a Category 3 hurricane. According to the National Weather Service, Hurricane Georges had sustained winds between 110 to 130 mph and gusts that probably exceeded 150 mph in the mountains of central Puerto Rico.
Electricity may be out and communication lines cut off by the tremendous winds and torrential rains of Hurricane Georges, but thanks to good foresight in "hardening" monitoring systems by the U.S. Geological Survey, real-time streamflow data in Puerto Rico continued to flow to reservoir operators, emergency officials, and others who need streamflow information and need it fast.
During the week of July 13-17, the U.S. Geological Survey (USGS) examined the coral reefs around Culebra, Puerto Rico.
Federal and local biologists captured and tagged three manatees in early August near Mayaguez, Puerto Rico, as part of efforts to better protect West Indian manatees inhabiting this Caribbean island.
The especially wet Hurricane Hortense has U.S. Geological Survey hydrologists and technicians working around the clock to measure its impact on the rivers of Puerto Rico. The Rio de la Plata in northeastern Puerto Rico, for example, has reached its highest level ever, exceeding the previous record high flow of Jan. 5, 1992, when the river reached a flow of 82 billion gallons per day.
