Click to hide Water-Year Summary instructions and information
  • Water-Year Summary reports summarize a year of hydrologic data in a printer-friendly format.
  • For water years 2014 onward, choose a water year and parameter and an on-demand Water-Year Summary report will be generated.
  • For water years 2006 through 2013, choose a water year and an Annual Water Data Report will be provided.
  • For water years 2005 and earlier, Annual Water Data Reports may be available in digital format.
  • Not all sites have reports available for every water year.

USGS Water-Year Summary 2022
LOCATION - Lat 46°10'53", long 123°10'56" referenced to North American Datum of 1927, in NE 1/4 sec.16, T.8 N., R.4 W., Columbia County, OR, Hydrologic Unit 17080003, on left bank, 0.7 mi downstream from Crims Island, 3.0 mi northwest of Quincy and at mile 53.8.
DRAINAGE AREA - 256,900 mi². approximately.
PERIOD OF RECORD - May 1968 to June 1970, June 1991 to current year. Prior to 2017, published as "at Beaver Army Terminal, near Quincy."
GAGE - Water-stage recorder and acoustic velocity meter. Datum of gage is Columbia River Datum. Subtract 1.00 ft from gage heights to convert to NGVD of 1929 gage heights. May 1968 to June 1970, water-stage recorder with auxiliary water-stage recorder at site 5.6 mi downstream, at datum 10.00 ft lower; June 27, 1991 to September 30, 2004, at present site, at datum 1.52 ft higher.
REMARKS - Flow regulated by many reservoirs on Columbia River and in tributary basins. Flow significantly affected by astronomical tides, which can cause reverse flow during tidal cycle when daily mean discharges are less than 250,000 ft³/s. Daily mean discharges since water year 2007 are computed from filtered unit value discharge data. The Godin low-pass filter is used to remove tidal variations from unit values. Continuous water-quality records for some prior periods have been collected at this location. Chemical analyses and periodic suspended sediment data collected at this location are available via NWISWeb.
EXTREMES FOR PERIOD OF RECORD - Maximum daily discharge, 864,000 ft³/s Feb. 10, 1996; minimum daily discharge, 63,600 ft³/s Sept. 9, 2001; minimum unfiltered discharge recorded since water year 2007, -279,000 ft³/s Oct. 15, 2012, but may have been less during periods of missing record.
