  • Notice - The USGS Water Resources Mission Area's priority is to maintain the safety and well-being of our communities, including providing critical situational awareness in times of flooding in all 50 U.S. states and additional territories. Our hydrologic monitoring stations continue to send data in near real-time to NWISWeb, and we are continuing critical water monitoring activities to protect life and property on a case-by-case basis. The health and safety of the public and our employees are our highest priorities, and we continue to follow guidance from the White House, the CDC, and state and local authorities.

SURFACE-WATER RECORDS
PERIOD OF RECORD - Jan. 1966 to Feb. 1967, Mar. 1992 to current year (daily mean discharges less than 2,950 ft³/s). Prior to Oct. 1994, published as "above Calallen".
GAGE - Water-stage recorder. Datum of gage is NGVD of 1929. Prior to Mar. 27, 1992, at same site at datum 6.04 ft higher. Satellite telemeter at station.
REMARKS - Water Year record is rated good. Since installation of gage in Jan. 1966, at least 10% of contributing drainage area has been regulated. Some records listed in the "Period of Record" for surface water and water quality may not be available electronically.
EXTREMES FOR PERIOD OF RECORD - Maximum gage height, 32.22 ft, Sept. 16, 2002; no flow at times.
WATER-QUALITY RECORDS
PERIOD OF RECORD - CHEMICAL DATA: Feb. 1966 to Mar. 2008. BIOCHEMICAL DATA: Feb. 1966. SEDIMENT DATA: May 2006 to July 2007.
PERIOD OF DAILY RECORD - SPECIFIC CONDUCTANCE: Nov. 2008 to current year. pH: Nov. 2008 to current year. WATER TEMPERATURE: Nov. 2008 to current year. DISSOLVED OXYGEN: Nov. 2008 to current year.
INSTRUMENTATION - A 4-parameter continuous water-quality monitor since Nov. 2008. Turbidity added in 2011.
REMARKS - Interruptions or periods of missing record may be due to instrument failure, no flow conditions or data corrections exceeding allowable criteria, which were deleted. Other than no flow conditions, minimum and maximum extremes may have occurred during period of missing record.
