USGS Water-Year Summary 2023
15388960 PORCUPINE RIVER NEAR INTERNATIONAL BOUNDARY, AK
LOCATION - Lat 67°25'27", long 140°53'28" referenced to North American Datum of 1927, UNSPECIFIED, Hydrologic Unit is unknown, 3.1 mi upstream from old townsite of Ramparts House, at Alaska-Yukon Territory Boundary.
DRAINAGE AREA - 22,750 mi². approximately.
SURFACE-WATER RECORDS
PERIOD OF RECORD - October 1987 to current year.
GAGE - Water-stage recorder. Elevation of gage is 600 ft above sea level, from topographic map.
COOPERATION - Discharge records furnished by the Water Survey of Canada.
REMARKS - Records fair except for estimated daily discharges, which are poor. Differences between data published herein and corresponding data in the reports of the Water Survey of Canada are due to variations in automated program techniques. After December 1978, data published in reports of the Water Survey of Canada are in International System (SI) units, and have been converted to inch-pound units for this report. Formerly the data reported in the USGS Water-Data Report were one year prior to those reported for U.S. gages because the Water Survey of Canada discharge records for the calendar year were not received until the following year. Since the 2003 water year, periods of record for this station are current with U.S. gage reports.
