USGS Surface-Water Data for Wyoming

Click to hide state-specific text
Updated July 6, 2016 : 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 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.

(157 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).

(715 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 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.

Annual maximum instantaneous peak streamflow and gage height

(1,000 sites)

Manual measurements of streamflow and gage height. These measurements are used to supplement and (or) verify the accuracy of the automatically recorded observations, as well as to compute streamflow based on gage height.


The U.S. Geological Survey's (USGS) National Water Information System (NWIS) is a comprehensive and distributed application that supports the acquisition, processing, and long-term storage of water data. Water Data for the Nation serves as the publicly available portal to a geographically seamless set of much of the water data maintained within NWIS (additional background).

Nationally, USGS surface-water data includes more than 850,000 station years of time-series data that describe stream levels, streamflow (discharge), reservoir and lake levels, surface-water quality, and rainfall. The data are collected by automatic recorders and manual field measurements at installations across the Nation.

Data are collected by field personnel or relayed through telephones or satellites to offices where it is stored and processed. The data relayed through the Geostationary Operational Environmental Satellite (GOES) system are processed automatically in near real time, and in many cases, current data are available online within minutes.

Once a complete day of readings are received from a site, daily summary data are generated and made available online. USGS finalizes data at individual sites on a continuous basis as environmental conditions and hydrologic characteristics permit.
