Questions or concerns about USGS streamflow data in Wyoming and Montana can be directed to Kirk Miller (kmiller@usgs.gov; 307-775-9168).

UPDATED May 1, 2018: USGS streamflow monitoring will be discontinued at the following sites effective July 1, 2018:
  • 06268600 Bighorn River at Worland, WY (1965 to present; 7 years)
  • 06299980 Tongue River at Monarch, WY (2004 to present; 13 years)
  • 06313500 Powder River at Sussex, WY (1938 to present; 46 years)
  • 06755960 Crow Creek at 19th Street at Cheyenne, WY (1993 to present; 24 years)
USGS streamflow monitoring will be discontinued at the following site effective October 1, 2018:
  • 06274300 Bighorn River at Basin, WY (1990 to present)
USGS monitoring activities at these sites were funded by partner agencies. Lack of partner funding for these sites results in discontinuation of all streamgaging activities. Questions or concerns can be directed to Kirk Miller (kmiller@usgs.gov; 307-775-9168).

(4 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.

(21 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).

(169 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

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.
