USGS Flood Update for Western Washington, Nov. 8, 2006

Overview:
A "pineapple express" storm system that brought intense rainfall to western Washington during the past three days has pushed river flows at 15 river gaging stations to new all-time record high flows, shown in the following table:

Currently, there are 9 river gaging stations above flood stage set by the National Weather Service. Of the river gaging stations with 30 or more years of record for today, 75 percent of them are at new record high flows for the day of the year.

USGS crews are now in the field, working to keep all gaging equipment in continuous operation, and to manually measure peak river flows under typically hazardous river conditions as trees and other large debris are flushed down the rivers.

Interest in streamflow data has been intense. In just the first six days of November, the USGS Washington Water Science Center’s Web site has received nearly 1,000,000 hits.

USGS river gaging stations form the backbone of flood-warning systems in the state. Federal agencies such as the Corps of Engineers and the National Weather Service, as well as state, county, and local emergency management agencies, use real-time streamflow data from USGS river gaging stations to monitor the rivers closely and to protect people and property.

Definitions and Abbreviations:
Gage height: The elevation of a river’s surface at a gaging station, in reference to an established elevation point. Sometimes called stage.
Flow: The amount of water flowing in a river past the gaging station, usually stated in cubic feet per second. Sometimes called streamflow or discharge.
Flood stage: The elevation of a river’s surface at a gaging station, determined by the National Weather Service, at which overflow of the natural banks of a river begins to cause damage in the local area by flooding.
ft = feet; cfs = cubic feet per second; NWS = National Weather Service
