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.
Hydrogeology of the Adelaida Area, San Luis Obispo County, CA
The USGS is conducting a comprehensive evaluation of groundwater resources of the Adelaida area. Use this map to explore the hydrogeology of the area, including land use, geology, and USGS hydrologic data by watershed or water management district.
TrendPowerTool: A web lookup tool for estimating the statistical power of a monitoring program to detect population trends
A simulation-based power analysis can be used to estimate the sample sizes needed for a successful monitoring program, but requires technical expertise and sometimes extensive computing resources. We developed a web-based lookup app, called TrendPowerTool.
LCMAP CONUS Mosaic Download Portal
A web based application used for searching and downloading LCMAP science products at the Conterminous United States (CONUS) scale.
Storm Summary Timelapse Dashboard (SSTL)
Many USGS water-resource monitoring sites have webcams installed to allow remote visibility of current water and environmental conditions, identify technical issues, verify remote measurements, and gather data for visual analyses. The Storm Summary Timelapse Dashboard (SSTL) displays many of these active webcams and provides access to still-frame images and timelapse videos of recent...
Pennsylvania Groundwater Quality Monitoring Network
USGS Pennsylvania Water Science Center, in cooperation with the Pennsylvania Department of Environmental Protection, samples 28 wells biannually to monitor ambient groundwater quality conditions in a variety of settings throughout Pennsylvania. The most recent results for selected constituents can be accessed through the Groundwater Quality...
Pennsylvania StreamStats
StreamStats is a national web-based application that provides selected water-resource information for Pennsylvania. Users can easily obtain descriptive information, basin characteristics, and streamflow statistics for USGS streamgages and ungaged stream locations throughout the Commonwealth. Water use data is also available for Pennsylvania in StreamStats.
