REMARKS - Record quality ratings may not be included in the water-year summary for approved records newer than 09/30/2018. Record quality is still being rated internally. For questions about record quality ratings, please send email to gs-w-nd_NWISWeb_Data_Inquiries@usgs.gov.

Accuracy of records for water years prior to 2014 are noted in the individual Annual Data Reports for those water years.

EXTREMES OUTSIDE PERIOD OF RECORD -

Contracted opening measurement, discharge 1,000 ft³/s, June 6, 1982, assumed stage 89.43 ft = 9.455 ft, gage datum using RM 1.

Discharge 26,300 ft³/s, August 10, 1962, from a slope-area measurement, made 2 mi upstream. Based on maximum discharges seen at downstream sites (example 05120000 Souris River Near Verendrye, ND had a peak of 1,380 ft³/s on August 12) indicates this discharge is highly suspect and is not published with the peak flows.
