Coastal Salinity Index
The location of the freshwater–saltwater interface along the coast is an important factor in the ecological and socioeconomic dynamics of coastal communities. Salinity is a critical response variable that integrates hydrologic and coastal dynamics including sea level, tides, winds, precipitation, streamflow, and tropical storms.

Fish Species Observations from Inland Chesapeake Bay Watershed Fish Samples
The following map summarizes data compiled within the Chesapeake Bay Watershed Inland Fisheries Database which comprises fish sampling data collected by federal and state agencies, river basin commissions, universities, and other organizations across the Chesapeake Bay Watershed.
USGS LMG WSC RESTORE Data Visualization Tool
This application provides a set of interactive data visualization tools to explore datasets generated by USGS researchers for the RESTORE project. The purpose of this tool is to help stakeholders, decision makers and other interested users access these datasets and develop a better understanding of spatial and temporal streamflow patterns in the Lower Mississippi-Gulf Region.
National Water Dashboard (NWD)
The National Water Dashboard (NWD) is a mobile, interactive tool that provides real-time information on water levels, weather, and flood forecasts - all in one place on a computer, smartphone, or other mobile device. The NWD presents real-time stream, lake and reservoir, precipitation, and groundwater data from more than 13,500 USGS observation stations across the country.
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.
WaterAlert
The U.S. Geological Survey WaterAlert service sends e-mail or text (SMS) messages when certain parameters, as measured by a USGS real-time data-collection station, exceed user-definable thresholds. The development and maintenance of the WaterAlert system is supported by the USGS and its partners, including numerous federal, state, and local agencies.
NWIS Current Water Data (Real-Time Data)
The USGS provides real-time or near-real-time conditions water data at sites across the Nation. Current data typically are recorded at 15- to 60-minute intervals, stored onsite, and then transmitted to USGS offices every 1 to 4 hours, depending on the data relay technique used. Recording and transmission times may be more frequent during critical events.
USGS Mobile Water Data
The USGS Mobile Water Data site highlights USGS current conditions water data in a mobile-friendly website, allowing users to monitor conditions at a favorite river or stream or locate nearby monitoring locations. All USGS current conditions water data is available.
How We Model Stream Temperature in the Delaware River Basin
Neural networks are powerful deep learning models that help us make accurate environmental predictions. This data visualization describes how to train an artificial neural network, and how the USGS uses them to make physically-realistic predictions with less data.
How We Monitor Stream Temperature in the Delaware River Basin
The USGS has been monitoring stream temperature in the Delaware River Basin since 1901, and has amassed over 650,000 daily temperature measurements. This data visualization story explores temporal and locational patterns in stream temperature observations, and how spatial variability and data gaps add complexity to prediction efforts.
