ALERT: December 5th update on the status of the nationwide data transmission error preventing stream gauge data collected at affected locations from being displayed on the Advanced Hydrologic Prediction Services (AHPS) webpages. As of 11/08/2018, The USGS has restored all impacted operational stream gauges to transmitting status. The status map of gauge outages from other agencies is here. The outage map will be updated each Thursday. We apologize for the service interruption and hope to have the data restored as soon as possible.

Low Water Impacts

If you notice any errors in the below information, please contact our Webmaster
700 cfs	Minimum base flow for August 15, September 1, September 15, October 1 and October 31 at this river gage, affecting water-rights junior to the base flows established June3, 1983 and prior to the 2008 rule.
900 cfs	Minimum base flow for August 15 and September 1 at this river gage, which is the lowest base flow of the year. The affected stream reach is from the mouth to the confluence of, and including, Derby Creek but excluding Mission Creek. Water-rights junior to the base flows established in this rule may be restricted if streamflow drops below this value. For more information on this and the minimum base flows for other times in the year and for other reaches, refer to Washington Administrative Code (WAC) Chapter 173-545.
