The colored dots on this map depict streamflow conditions as a percentile, which is computed from the period of record for the current day of the year. Only stations with at least 30 years of record are used.
The gray circles indicate other stations that were not ranked in percentiles either because they have fewer than 30 years of record or because they report parameters other than streamflow. Some stations, for example, measure stage only.
Go to the

Current Streamflow Conditions Table


Current conditions data typically are recorded at 15-60 minute intervals, stored onsite, and then transmitted to USGS offices in Wyoming every hour. Recording and transmission times may be more frequent during critical events. Data from current conditions sites are relayed to via satellite and are available for viewing within minutes of arrival.

All real-time data are provisional and subject to revision.
