USGS Current Water Data for Nevada
The Nevada Water Science Center is transitioning to a new data management software package starting the week of June 19, 2017. While you may not notice this transition, some sites may have problems or delays in being updated. We are actively monitoring these conditions and are resolving them as quickly as possible. See the Dec 8 news entry for more information at: https://help.waterdata.usgs.gov/news
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.
The data on these pages is made possible with the cooperation from
Federal, Tribal, State, and local agencies.
