StreamNet OnLine

StreamNet is a cooperative venture of the Pacific Northwest's fish and wildlife agencies and tribes. They provide data and data services in support of the region's Fish and Wildlife Program and other efforts to preserve and restore the region's aquatic resources.

Dreamflows (NEW)

Dreamflows is a fully automated system that polls the Internet for stream and reservoir data, and stores it in a database.  It also estimates the flows at some sites, based on the flows at other, known, sites.  It correlates all this flow data and uses it to create a daily report.  Dreamflows emails the report to all subscribers who requested one on that day, and at the same time updates the current Daily Dreamflows report webpages.

Dreamflows also maintains a separate database, with realtime flow information for select rivers (currently California and Nevada only), including a number of estimated flows.  Dreamflows updates this database every 30 minutes during the day, every hour at night, and at the same time updates the Realtime report page.
