Water
Get current water conditions that are important to you, such as water levels, streamflow, temperatures, and more.
Freshwater Flow into Chesapeake Bay
The USGS provides estimates of the monthly and annual amounts of freshwater flow into the Bay so scientists and managers can better understand effects on ecosystem conditions.
USGS Installed Wells - San Diego County, CA
Summary tables of data for USGS installed wells in San Diego County, CA. Included are links to data sets, including well construction, geophysical logs, lithologic logs, groundwater levels, water quality, and streamgages.
Puget Sound Real-Time Water-Level Data
The chart shows the most recent 7 days of data at all Puget Sound water level sites with available data. Use mouse scroll wheel to zoom and drag to pan. Sites include Bellingham, Oak Harbor, Edmonds, Lofall, Steilacoom, and Olympia.
Drought Streamflow Probabilities in Northeast Region
Maximum likelihood logistic regression (MLLR) is used to estimate drought probabilities for selected Northeast rivers and streams. Winter streamflows are used to estimate the chance of hydrologic drought during summer months. This application allows the display and query of these drought streamflow probabilities for Northeastern streams.
Detailed Aquifer Mapping Program in Upstate New York
Define the hydrogeology of extensively used (primary) stratified-drift aquifers in upstate NY, and present the information as individual sets of maps at 1:24,000 scale. Each published report describes the hydrogeology of a specific aquifer or segment, and depicts selected hydrogeologic characteristics. Continue the hydrogeologic assessment and mapping of selected principal aquifers in upstate...
WaterWatch (surface water)
WaterWatch displays maps, graphs, and tables describing real-time, recent, and past streamflow conditions for the United States, including flood and droughts. Real-time information generally is updated on an hourly basis.
Groundwater Watch
Groundwater Watch displays maps, graphs, and tables describing real-time, recent, and historical groundwater data from wells and springs across the United States. Groundwater Watch groups related wells and data from active well networks and provides basic statistics about the water-level data collected by the USGS and from data supplied to us from partners through cooperative agreements.
WaterQualityWatch
WaterQualityWatch provides access to real-time water-quality data collected at more than 2,000 stream sites throughout the United States, including streamflow, water temperature, specific conductance, pH, dissolved oxygen, turbidity, and nitrate.
WaterNow
The USGS WaterNow service lets users receive current conditions for USGS water-data-collection stations on demand via email or cell-phone text message. The user sends an email or text message containing a USGS current-conditions gaging site number, and will quickly receive a reply with the station's most recent data for one or more of its monitored parameters.
USGS Surface-Water Data for the Nation
Real-time, daily, peak-flow, field measurements, and statistics of current and historical data that describe stream levels, streamflow (discharge), reservoir and lake levels, surface-water quality, and rainfall across the U.S. Surface-water data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.
USGS Water-Quality Data for the Nation
Chemical, physical, and biological properties of water, sediment, and tissue samples from across the U.S. Water-quality data are collected as either discrete field measurements or as continuous time-series data from automated recorders that continuously record physical and chemical characteristics including pH, specific conductance, temperature, and dissolved oxygen.
USGS Groundwater Data for the Nation
Data from wells, springs, test holes, tunnels, drains, and excavations across the U.S.; well location data includes information such as latitude and longitude, well depth, and aquifer. Groundwater level data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.
