USGS Water-Year Summary 2021
LOCATION - Lat 48°22'16", long 121°04'35" referenced to North American Datum of 1927, Skagit County, WA, Hydrologic Unit 17110005, on left bank of creek.
DRAINAGE AREA - 0.08 mi².
PERIOD OF RECORD - June 1961 to November 1975 (fragmentary), May 1976 to September 1993, October 2002 to February 2003, July 2003 to September 2012, October 2013 to current year (fragmentary).
GAGE - Water-stage recorder in a structure that channelizes creek into 3 ft wide flume leading to a V-notch weir located at its downstream end. The V-notch weir is the control at all stages, with the exception of very high flow, which may not be contained by the gage structure.  Discharge was classified as a high-precision weir beginning in October 2015 in order to compute daily discharge values to the thousandth of a cubic feet per second.  Elevation of gage is 5200 feet above NGVD of 1929, from topographic map. Gage height of zero is at the elevation of the bottom of the notch (zero flow). 
REMARKS - No regulation or diversion.
