Our scientists gather information through periodic or continuous measurement in the field to provide a view of current conditions. In some instances, observations may not be subject to rigorous review before release; this will be noted in the documentation accompanying the data.

Shift Adjusted Ratings for Georgia, North and South Carolina Stream Gages Shift Adjusted Ratings for Georgia, North and South Carolina Stream Gages

Use the URL below to view the shift-adjusted rating table for any USGS site. Stage-discharge relationships (ratings) are primarily developed from a graphical analysis of multiple streamflow measurements.

South Dakota Ground Water Data South Dakota Ground Water Data

Data from wells, springs, test holes, tunnels, drains, and excavations in South Dakota; 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.

South Dakota Surface Water Data South Dakota Surface Water Data

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 in Wisconsin. Surface-water data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.

South Dakota Water Quality Data South Dakota Water Quality Data

At selected surface-water and groundwater sites, the USGS maintains instruments that continuously record physical and chemical characteristics of the water including pH, specific conductance, temperature, dissolved oxygen, and percent dissolved-oxygen saturation. Supporting data such as air temperature and barometric pressure are also available at some sites.

StreamStats for New Jersey StreamStats for New Jersey

The USGS StreamStats website is a GIS-based web tool for estimating streamflows at gaged and ungaged locations. Features similar to the National Streamflow Statistics program are presented to users with no programs to install. Users can visit the StreamStats website linked here and click on a stream location on the interactive map to compute estimated streamflows for floods and other...

Treasure Valley Drains Treasure Valley Drains

To begin filling data gaps for development of a Treasure Valley groundwater-flow model, we installed 10 new real-time streamgages on drains along the lower Boise River from Eagle to Parma. The streamgages will monitor the amount of shallow groundwater the aquifer system discharges to surface water. This was a missing component in previously developed models.
