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

UPDATED December 12, 2017: USGS streamflow monitoring will be discontinued at the following site effective July 1, 2018:
  • 06755960 Crow Creek at 19th Street at Cheyenne, WY (1993 to present)
USGS streamflow monitoring will be discontinued at the following site effective October 1, 2018:
  • 06274300 Bighorn River at Basin, WY (1990 to present)
USGS streamflow monitoring was discontinued at the following sites effective October 1, 2017:
  • 06225000 Bull Lake Creek near Lenore, WY (1918 to present)
  • 06225500 Wind River near Crowheart, WY (1945 to present)
  • 06317020 Wild Horse Creek near Arvada, WY (2000 to present)
  • 06425720 Belle Fourche River below Rattlesnake Creek near Piney, WY (2001 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).

(1985-2010)

State water-use data are reported by source (surface water or groundwater, fresh and saline, and total), category, and area type (county). The water-use data presented here are the current best estimates, and may have been revised from previous publications. Data collection varied between the different compilations. Pre-1995 datasets have more data available than 2000 and later. A chart is available that provides for a conceptual picture of the changes in water-use categories between compilations.

The details of a water-use category sometimes changed between compilations. For example, for 1985-1995, thermoelectric power withdrawal data was grouped by fuel type, but for 2000-2010, thermoelectric power data was grouped by the cooling method (once-through or closed-loop).

Introduction

The USGS's National Water Use Information Program compiles and publishes the Nation's water-use data. Public access to some of these data is provided via the USGS Water Data for the Nation site (additional background). Water use refers to water that is used for specific purposes. Water-use data is collected by area type (State, county, watershed or aquifer) and source such as rivers or groundwater, and category such as public supply or irrigation. Water-use data has been reported every five years since 1950, for years ending in "0" and "5". The USGS works in cooperation with local, State, and Federal agencies as well as academic and private organizations to collect and report total withdrawals.

Annual water-use data are expressed in units of million gallons per day (abbreviated as Mgal/d) and thousand acre-feet per year. For the irrigation category, water-use data are the average daily quantities used over a period of a year and do not represent actual daily rates. In most parts of the nation, irrigation water is applied during only a part of each year and at variable rates; therefore, the actual rate of application is much greater than the average daily rate. For all other categories, the daily quantity of water that is withdrawn may be based on daily usage or more often, monthly usage that is averaged to a daily quantity.
