Daily Streamflow Conditions

Select a site to retrieve data and station information.
Stream gage levels in Washington, relative to 30 year average.

Explanation
	High
	> 90th percentile
	75th - 89th percentile
	25th - 74th percentile
	10th - 24th percentile
	< 10th percentile
	Low
	Not ranked

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.
