Real-time Data

Our scientists gather information through periodic or continuous measurement in the field to provide a view of current conditions. In some instances, observations may not be subject to rigorous review before release; this will be noted in the documentation accompanying the data.

GAMA-Priority Basin Project Groundwater-Quality Results: Assessment and Trends

This interactive webmap plots water-quality data from domestic and public-supply wells sampled by the USGS for the California Groundwater Ambient Monitoring and Assessment Program (GAMA) Priority Basin Project, and allows users to download datasets.

Water use in the U.S., 2015

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 looks like this:

USGS Water Use Data for the Nation

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.

MODFLOW-NWT model used to simulate groundwater storage changes in the Quincy Basin, Washington

A three-dimensional, groundwater flow model (MODFLOW-NWT) was developed to examine groundwater storage changes in the Quincy Basin, Washington. The model was calibrated to conditions from 1920 to 2013. The model was used to (1) determine the change in groundwater storage from 1920 to 2013 , and (2) simulate the potential effects of increases in pumping.

Streamflow and water-quality samples collected during 2018 and 2019

Data Used to Characterize Peak Streamflows and Flood Inundation Resulting from Hurricane Harvey

In the immediate aftermath of Hurricane Harvey, the USGS and FEMA worked together to document the storm event in southeastern Texas and southwestern Louisiana.  This data release contains the flood inundation polygons, flood-depth rasters, mapped boundaries, and high-water mark (HWM) locations for the selected river basins, coastal basins, and coastal areas that flooded in Texas and Louisiana.

Post-Fire Debris Flows

Estimates of the probability and volume of debris flows that may be produced by a storm in a recently burned area, using a model with characteristics related to basin shape, burn severity, soil properties, and rainfall.

U.S. Water Use from 1950-2015

How much water do we use?
In the map below, State size (area) is scaled proportionally to State freshwater use.

USGS SWaTH Network

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.
