Short Description	This is a Quality Assurance Monitoring Plan for the Department of Ecology's Streamflow Gaging Network. Revisions made October 2007: Under "Dividing the Stream Channel into Segments" section, the number of segments in a measurement cross-section was increased to approximately 30 segments. The "Measuring Velocity of the Stream Segments" section was re-written to include the following updates: The number of measurement segments was increased to better address horizontal variability. The methods employed to address vertical variability in a measurement segment were updated. Velocity sampling times were updated to better address single-point velocity variation.

Abstract	Long Description
	Management of surface water in Washington State requires a streamflow measurement network capable of monitoring water diversions, minimum instream flows, and water availability, as well as detecting trends in all parts of the state. The Department of Ecology operates a streamflow gaging network program focused on obtaining information for water resource management needs. This document presents detailed information on each of the 14 elements required of a Quality Assurance Monitoring Plan. Any changes to methods or evaluation approaches described in this plan will be updated on Ecology′s website.
