Real-time Data

The VegDRI and QuickDRI are complementary drought monitoring tools that show drought patterns at relatively high spatial detail compared to traditional drought indicators.

Many volcanoes in the U.S. are monitored by arrays of several instruments that detect subtle movements within the earth and changes in gas and water chemistry. The Volcano Hazards Program streams this data to its Volcano Observatories and makes it available on volcano-specific websites.

The National Water Information System (NWIS) provides map-interface access to data at over 1.5 million water-monitoring sites.

Table-based interface allow you to get the latest water-quality data for thousands of water monitoring sites in the Nation.

Realtime Water Quality Data

Chemical, physical, and biological properties of water, sediment from Maryland, Delaware, and Washington DC sources. 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.

Stream water-quality characteristics provide scientists and water managers with a better understanding of the effects of natural and anthropogenic (human) activities on streams and ecosystems. The USGS operates a network of near-real-time water-quality monitoring stations that provide data for temperature, specific conductance, pH, dissolved oxygen, and turbidity of surface water.

Realtime Water Use Data

Chemical, physical, and biological properties of water, sediment, and tissue samples from Nebraska. 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.

Chemical, physical, and biological properties of water, sediment, and tissue samples from Wisconsin. 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.

Summaries of water-quality monitoring data are now available for several major river basins in Colorado. For each basin, current data from a network of sites are compared to previously collected data and instream standards. Lowess curves are provided on plots for selected constituents where a sufficient period of record and limited censored data are available.

Water-use data is collected by area type (state, county, watershed, or aquifer) and source (such as rivers or groundwater), and category (such as public supply or irrigation). Water-use data has been reported every five years since 1950. The USGS works in cooperation with local, State, and Federal agencies as well as academic and private organizations to collect and report withdrawals.
