Real-time Data

A site on the Rio Grande near the town of Embudo, New Mexico, was established as the first USGS training camp for hydrographers. See Publications: Embudo, New Mexico, birthplace of systematic stream gaging | The USGS at Embudo, New Mexico: 125 years of systematic streamgaging in the United States

The Ground-Water database contains ground-water site inventory, ground-water level data, and water-quality data. Additional ground-water information for New Jersey is available at the New Jersey Water Science Center web page. This page includes geologic maps, a description of the aquifers in New Jersey, and references to selected ground-water reports.

This map interface represents continuous and discrete water-quality data collected by Bureau of Reclamation and USGS at Klamath Basin sites. The USGS and Reclamation data stored in NWIS are accessible using existing tools such as NWIS-Web and the USGS Data Grapher system.

The National Water Information System (NWIS) is the USGS water data portal where you can find a wealth of historic and real-time data related to floods. The NWIS website also is where you can query peak streamflow data by station, state ( Wyoming or Montana), or region.

Access to current conditions, historical observations, daily data, statistics, peak-flow data, and field measurements for streamflow gaging stations in Arizona.

Nationally, USGS surface-water data includes more than 850,000 station years of time-series data that describe stream levels, streamflow (discharge), reservoir and lake levels, surface-water quality, and rainfall. The data are collected by automatic recorders and manual field measurements at installations across the Nation.

SWaTH is a system of flood-hardened, real-time telemetered tide gages, rapid deployment gages, and storm tide sensors deployed in integrated network configurations along the Northeastern Atlantic Coast from North Carolina to Maine.

National water-use data are reported by source (surface water or groundwater, fresh and saline, and total), and category for the United States as a whole. The water-use data presented here are the current best estimates, and may have been revised from previous publications.

At selected surface-water and ground-water sites, the USGS maintains instruments that continuously record physical and chemical characteristics of the water including pH, specific conductance, temperature, dissolved oxygen, turbidity, and percent dissolved-oxygen saturation. At sites where this information is transmitted automatically, data are available from the real-time data system.

How do we use water in the U.S.? We all depend on water every day, ranging from the water from our faucets, to the food we eat, to much of the electricity we use. The U.S. and its territories used nearly 322 billion gallons of water per day in 2015. This would cover the continental U.S. in about two inches of water over the course of a year. The national breakdown of water withdrawals...

WaterWatch is a U.S. Geological Survey (USGS) World Wide Web site that displays maps, graphs, and tables describing real-time, recent, and past streamflow conditions for the United States.
