Data and Tools
RTD- Water
Water
Get current water conditions that are important to you, such as water levels, streamflow, temperatures, and more.
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.

Walla Walla County Groundwater Watch
Network wells depicted on the Walla Walla County, WA location map Note: Color shading in the table below indicates multiple wells that plot as a single point on the state location map above. Note: BLS = Water Level in Feet Below Land Surface, RVD = Water Level referenced to a vertical datum
Profile Analysis Tool - Detroit Lake, OR
Lake profiler used to display water-quality data in Detroit Lake, OR. These data also provide insights into the evolution, behavior, and decay of the seasonal blooms which can inform management strategies, modeling, and perhaps prediction of blooms in the future.
Surface water sites associated with the hydrologic assessment of the Blackfeet Reservation, Montana
Surface water sites associated with the hydrologic assessment of the Blackfeet Reservation in Montana.
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.
