Water-Monitoring Sites in Montana and Wyoming

USGS's National Water Information System Web (NWISWeb) provides access to water-resources data collected at approximately 1.5 million sites throughout the Nation. We offer real-time data for hundreds of surface-water, groundwater, water-quality, and precipitation sites in Wyoming and Montana, as well as historical and summary data and statistics. Use the forms below to search for data for a particular site. NWISWeb help is available for the data categories below.

Real-Time Data  Real-time data are time-series (recorded at fixed intervals) data from automated equipment and represent the most current hydrologic conditions. Measurements are commonly recorded at 5-60 minute intervals and transmitted to the NWIS database every 1-4 hours. Real-time data are available online for 31 days.tiny question gif

Daily Data  Daily data are derived by summarizing time-series data for each day for the period of record. The time-series data used to derive daily values, sometimes referred to as real-time or instantaneous values may be collected as often as every minute. These data are used to calculate daily data, such as the daily mean, median, maximum, minimum, and/or other derived values. Daily data include approved, quality-assured data that may be published, and provisional data, whose accuracy has not been verified.tiny question gif

Streamflow Statistics  Statistics are computed from approved daily mean time-series 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.tiny question gif

Streamflow Measurements  Long-term records of physical measurements of streamflow. Data include date and time, gage height, mean velocity, stream width, shift adjustments, and controls.tiny question gif

Water-Quality Samples  Data from field and/or laboratory analyses of water samples, biological tissue, stream sediments, or other environmental samples. Data include approved, quality-assured data that may be published, and more recent provisional data, whose accuracy has not been verified.tiny question gif

Site Information  The Site Inventory System contains and provides access to inventory information about sites at stream reaches, wells, test holes, springs, tunnels, drains, lakes, reservoirs, ponds, excavations, and water-use facilities.

About 300 components make up the descriptive elements of the site inventory. The retrieval program can be used for retrieving information about sites in summary lists, in detailed tables, or a file suitable for input to other programs.

Streamflow Duration Hydrographs (from Water Watch)  Duration hydrographs from WaterWatch display a plot for the past two years that depicts the daily maximum, minimum, and 90th, 75th, 25th, and 10th percentiles for the period of record, along with the daily mean flow for each USGS real-time station having at least 20 years of record.tiny question gif
