Click to hide state-specific text

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

UPDATED October 1, 2020: USGS current stream monitoring information will continue at the following sites with funding from partner agencies and USGS Cooperative Matching Funds: UPDATED July 12, 2020: USGS current streamflow monitoring information will be discontinued at the following sites effective August 1, 2020:
  • 06289600 West Pass Creek near Parkman, WY (37 yrs)
  • 06289820 East Pass Creek near Dayton, WY (37 yrs)
  • 06297500 Highline Ditch near Dayton, WY
  • 06311400 North Fork Powder River below Pass Creek near Mayoworth, WY (46 yrs)
  • 06392900 Beaver Creek at Mallo Camp near Four Corners, WY (37 yrs)
  • 06392950 Stockade Beaver Creek near Newcastle, WY (37 yrs)
  • 06429500 Cold Springs Creek at Buckhorn, WY (37 yrs)
USGS monitoring activities at these sites had been supported through June 30, 2020 with funding from our partner agency and USGS cooperative matching funds. Without funding from another partner, current water-resources information from these sites will no longer be available from the USGS. Historical data will continue to be available from USGS. Questions or concerns can be directed to Kirk Miller (kmiller@usgs.gov; 307-775-9168).

(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.

(22 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).

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.

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.
