USGS Groundwater Data for Nebraska

Click to hide state-specific text

Current Conditions
(52 sites)

Current conditions at selected sites based on the most recent data from on-site automated recording equipment. Measurements are commonly recorded at a fixed interval of 15- to 60-minutes and transmitted to the USGS every hour. Values may include "Approved" (quality-assured data that may be published) and/or more recent "Provisional" data (of unverified accuracy and subject to revision). Most current data are provisional.

Historical Observations
(89 sites)

The same data accessed by the Current Conditions link above but including both active and discontinued sites with data for any part of the period October 1, 2007, through the present. Values may include "Approved" (quality-assured data that may be published) and/or more recent "Provisional" data (of unverified accuracy and subject to revision).

Daily Data
(133 sites)

Summary of all data for each day for the period of record and may represent the daily mean, median, maximum, minimum, and/or other derived value. Values may include "Approved" (quality-assured data that may be published) and/or more recent "Provisional" data (of unverified accuracy and subject to revision). Example.

Statistics
(36 sites)

Statistics are computed from approved daily mean data at each site. These links provide summaries of approved historical daily values for daily, monthly, and annual (water year or calendar year) time periods.

Field Measurements
(22,216 sites)
Manual measurements of depth to water in wells.
Introduction

The Groundwater database contains groundwater site inventory, groundwater level data, and water-quality data.

The Nebraska groundwater site database consists of more than 28,000 records of wells, springs, and test holes in Nebraska. Available site descriptive information includes well location information (latitude and longitude, well depth, site use, water use, and aquifer).

In 1930, the Conservation and Survey Division (CSD) of the University of Nebraska and the USGS began a cooperative water-level measurement program to observe and document, on a continuing basis, the changes in groundwater levels throughout Nebraska. As a part of that program, the USGS has maintained and updated this groundwater level data- base, which includes water levels from the following agencies and associations: CSD, USGS, Natural Resources Districts (NRDs), Groundwater Conservation Districts, U.S. Bureau of Reclamation, U.S. Fish and Wildlife Service, Central Nebraska Public Power and Irrigation District, County Extension offices, Omaha Metropolitan Utilities District, and Lincoln Water System. Since 1974, most water levels have been measured by NRDs.
