DRAINAGE AREA - 30,100 mi² of which 3,800 mi² probably is noncontributing. including 3,800 mi² in closed basins.

REVISIONS HISTORY - WSP 855: 1936(M). WSP 1115: 1942. WSP 1175: 1897(M). WSP 1388: 1904, 1914-15, 1917-19, 1921-22, 1927, 1950. WSP 1728: Drainage area. WRD-ND-81-1: 1882, 1897 (M).

SURFACE-WATER RECORDS

PERIOD OF RECORD -

PERIOD OF RECORD.--DAILY DISCHARGE--April 1882 to current year. Prior to September 1902 (all monthly periods) and September 1929 (for winter months only), daily values are derived from monthly totals published in WSP 1308.

PERIOD OF RECORD.--DAILY GAGE HEIGHT--September 1902 to current year. History of daily gage height record is shown below;

Prior to 1923: a nonrecording gage was read to quarter-tenths twice daily.

1923 to November, 3, 1933: a nonrecording gage was read to tenths once daily.

November 4, 1933, to present: recording gage operated to tenths or less than tenths accuracy.

GAGE - Water stage recorder with concrete control. Datum of gage is 780.00 ft above North American Vertical Datum 1988 (NAVD88, Survey by USGS) and 779.00 ft. above National Geodetic Vertical Datum 1929 (NGVD29).

Previous locations and datums are as follows:

1882-92: staff gages near site of Northern Pacific Railway bridge 0.4 mi downstream, datum unknown.
1892 to October 15, 1926: staff gage and chain gages on Northern Pacific Railway bridge 0.4 mi downstream at datum of about 778.35 ft (NGVD29)
October 16, 1926 to November 2, 1933: staff gages about 1.9 mi downstream at datum of 778.35 ft (NGVD29)
November 3, 1933, to April 13, 1965: water-stage recorder 1.6 mi downstream at datum of 778.35 ft (NGVD29)
April 14, 1965, to September 30, 1983: water-stage recorder 1.9 mi downstream at datum of 778.35 ft (NGVD29)
October 1, 1983, to September 30, 1986: gage at present location at datum of 780.00 ft (NGVD29)

REMARKS - Accuracy of records for water years prior to 2014 are noted in the individual Annual Data Reports for those water years. For water years 2014 onward, records good except for estimated discharges, which are poor, unless otherwise noted.

EXTREMES FOR PERIOD OF RECORD - Maximum peak flow, 137,000 ft³/s, April 18, 1997. Maximum observed, affected by breakout from Red River of the North about 20 mi upstream of gage that entered Red Lake River about 2 mi upstream of confluence with the Red River of the North. Maximum peak stage, 54.35 ft, April 22, 1997, from floodmark.
