Data

The U.S. Geological Survey has a database/archive of about 850,000 wells across the Nation. A well with below normal groundwater levels is identified when the most recent water-level measurement is in the 24th percentile or lower in the month of measurement over the period of record for the well.

Mineral groups identified through automated analysis of remote sensing data acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) were used to generate a map showing the type and spatial distribution of hydrothermal alteration, other exposed mineral groups, and green vegetation across the northwestern conterminous United States. Boolean algebra was used...

Groundwater well networks for Natural Resources Districts in Nebraska. Real-time, continuous, and periodic data are available.

Real-time computed concentrations of water-quality constituents such as suspended sediment, total nitrogen, and total phosphorus are calculated using ordinary least squares regression models. The results of these models, along with direct water-quality measurements, can be viewed here as time-series graphs, or downloaded as tabular data.

The point and polygon layers within this geodatabase represent locations of mineral occurrences, mines, mining and mineral districts and sites of active mineral exploration within or near the Department of the Interior (DOI) Sagebrush Focal Areas in Montana, Wyoming and Utah, central Idaho, and the Oregon-Nevada-Idaho border area. The data were compiled by the U.S. Geological Survey...

This data release has been updated in 2017 with a newer version that includes additional states. It is recommended to use the updated data and map services of the new data release located at: https://doi.org/10.5066/F78W3CHG These data are part of a larger USGS project to develop an updated geospatial database of mines, mineral deposits and mineral regions in the United States. Mine and...

The polygon (vector) feature class represents locatable mineral resource assessment tracts (tracts of land) associated with the Department of the Interior (DOI) Sagebrush Focal Areas in Montana, Wyoming and Utah, central Idaho, and the Oregon-Nevada-Idaho border area. The mineral resources tracts are geographic areas that were assessed by the U.S. Geological Survey (USGS) and were...

Maps of flood and high flow conditions within Kansas

WaterQualityWatch provides access to real time water-quality data collected in surface waters in Kansas, including streamflow, water temperature, specific conductance, pH, dissolved oxygen, turbidity, and nitrate.

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.

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

From February 12 to March 8, 1981, EG and G Geometrics conducted an aeromagnetic survey in Montana for Anaconda Copper Company. A Piper Navajo aircraft was used to conducted the survey. The survey was flown along north-south flightlines spaced 660 feet at a nominal height of 450 feet above the terrain. Five uniformly spaced east-west tie-lines were also flown. During processing, the...
