Updated UPDATE November 8, 2016 : USGS streamflow monitoring has been discontinued at the following sites effective November 8, 2016:
  • 06426130 Donkey Creek near Gillette, WY (2000 to present)
  • 06426160 Stonepile Creek at mouth near Gillette, WY (2000 to present)
USGS streamflow monitoring was discontinued at the following sites effective July 1, 2016:
  • 06306250 Prairie Dog Creek near Acme, WY (1970 to present)
  • 06324000 Clear Creek near Arvada, WY (1915 to present)
  • 06625000 Encampment River at mouth near Encampment, WY (1940 to present) UPDATE March 18, 2016 : Partner funding restored for site. USGS operation and maintenance will continue.
  • 06647500 Box Elder Creek at Boxelder, WY (1946 to present)
  • 06652800 North Platte River below Glendo Reservoir, WY (1957 to present)
Monitoring activities at these sites (map) were funded jointly by the USGS and a partner agency through the USGS Cooperative Water Program (http://water.usgs.gov/coop/). Lack of partner funding for these sites after June 30, 2016 resulted in discontinuation of all monitoring activities. Questions or concerns can be directed to Kirk Miller (kmiller@usgs.gov; 307-775-9168) or Wayne Berkas (wrberkas@usgs.gov; 406-457-5903).

Current Conditions
(5 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
(13 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
(161 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
(11 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
(10,440 sites)
Manual measurements of depth to water in wells.
Introduction

May 22, 2012: Groundwater-level monitoring at most wells in Wyoming will be discontinued June 30, 2012 due to insufficient funding. Historical data will continue to be available through NWISWeb. Direct questions to Kirk Miller 307/775-9168.

The USGS National Water Information System (NWIS) contains extensive water data for the nation. Public access to many of these data is provided via the USGS Water Data for the Nation site (additional background).

The Groundwater database consists of more than 850,000 records of wells, springs, test holes, tunnels,drains, and excavations in the United States. Available site descriptive information includes well location information such as latitude and longitude, well depth, and aquifer.
The USGS annually monitors groundwater levels in thousands of wells in the United States. Groundwater level data are collected and stored as either discrete current groundwater data. Once a complete day of readings are received from a site, daily summary data are generated and made available online. Annually, the USGS finalizes and publishes the daily data in a series of water-data reports.
