This interactive map shows river gauges listed at Dreamflows.com, a website geared toward river runners that provides flow and other information for rivers throughout the Western United States. Flow data for the gauges on this map are taken directly from the 'realtime' and 'daily' reports provided by Dreamflows. Realtime gauges are updated hourly, and daily gauges are updated every day at 5pm Pacific Time.
|Flow is known, but flow ratings are not available for this gauge|
|Flow is not known, but other information such as gauge height may be available|
|No flow information currently available|
Locations entered in the 'Center map at:' text box are marked with .
Flow ratings, provided by Dreamflows, are given as a general guideline and should be used with discretion; what is considered 'high', 'low', 'good', or 'optimum' will obviously vary from one river runner to the next.
Also note that some gauges do not have 'optimum' levels set for them, and many others do not have any ratings associated with them at all, so showing only gauges with 'good' or 'optimum' flows may exclude some that do in fact have favorable levels.
For more information about flow ratings and the levels which determine them, see the trigger levels page on the Dreamflows site.
Hover over markers for a 'tooltip' showing the gauge name and recent flow. Click on markers to open a window with more information.
