SURFACE-WATER RECORDS

PERIOD OF RECORD - DAILY DISCHARGE--October 2001 to current year. October 1981 to September 2001 equivalent discharge site formerly published as James River at Dakota Lake Dam near Ludden (06470875).

PERIOD OF RECORD.--DAILY GAGE HEIGHT--November 1981 to September 1999, October 2001 to current year.

GAGE -

Acoustic doppler velocity meter and water-stage recorder. Datum of gage is 1,200.88 ft above the North American Vertical Datum of 1988 (NAVD88) and 1,200.00 ft above the National Geodetic Vertical Datum of 1929 (NGVD29, levels by USBR).

REMARKS -

Discharge is heavily influenced by wind speed and direction. Negative discharge values are generally the result of southerly winds.

REGULATION AND DIVERSION.--Flow regulated by Jamestown Reservoir, capacity, 220,980 acre-ft, since 1953, Pipestem Lake, capacity 147,110 acre-ft, since 1973. Small amounts can be diverted to or from Hyatt Slough, which is 1 mile east of station and is connected by road ditch containing culvert gates.

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 flows less than 100 ft³/s and estimated discharges, which are poor, unless otherwise noted.

EXTREMES FOR PERIOD OF RECORD - Maximum peak flow, 11,800 ft³/s, April 18, 2009, peak stage, 96.35 ft, from floodmark; maximum peak stage, 98.04 ft, April 6, 1997, from floodmark at present location. Reverse flow on July 20, 2006, wind aided.

WATER-QUALITY RECORDS

PERIOD OF RECORD - Water year 2002 to 2012.
