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 2024
06838000 Red Willow Creek near Red Willow, Nebr.
LOCATION - Lat 40°14'05", long 100°30'03" referenced to North American Datum of 1983, in NE 1/4 NE 1/4 sec.17, T.3 N., R.28 W., Red Willow County, NE, Hydrologic Unit 10250007, on left bank near downstream side of bridge on U.S. Highways 6 and 34, 0.8 mi north of Red Willow and 2.1 mi upstream from mouth.
DRAINAGE AREA - 820 mi² of which 415 mi² probably is noncontributing.
REVISIONS HISTORY - WSP 1510: 1945(M). WDR NE-94-1: Drainage area.
SURFACE-WATER RECORDS
PERIOD OF RECORD - September 1939 to current year.
GAGE - Water-stage recorder with satellite telemetry. Datum of gage is 2,399.41 ft above North American Vertical Datum of 1988 (NAVD88). May 26, 1945 to August 16, 2017 at 2,398.64 ft above National Geodetic Vertical Datum of 1929 (NGVD29). Prior to May 26, 1945, non-recording gage at bridge 1.2 mi upstream at 2,409.80 above NGVD29 ; May 26, 1945 to Aug. 2, 1974, water-stage recorder at left downstream side of bridge, datum 2,398.64 ft above NGVD29 ; Aug. 3, 1974 to June 27, 1980, on right bank at downstream side of bridge, datum 2,398.64 ft NGVD29 ; and June 28, 1980 to May 19, 1992, at left downstream side of bridge, datum 2,398.64 ft above 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 fair except for estimated daily discharges, which are poor, unless otherwise noted. Natural flow affected by irrigation development above station, since September 5, 1961 by storage in Hugh Butler Lake (06837390); and since June 1963 by Red Willow Canal, which diverts 4.5 mi above station for irrigation of about 4,150 acres.
EXTREMES FOR PERIOD OF RECORD - Before regulation by Hugh Butler Lake, maximum discharge, 30,000 ft³/s, June 22, 1947, from rating curve extended above 6,800 ft³/s on basis of slope-area measurement of peak flow, gage height, 18.36 ft; minimum daily discharge, 2.0 ft³/s, July 29-31, 1954, and September 10, 1961. Since beginning of storage in Hugh Butler Lake, maximum discharge, 3,900 ft³/s, May 23, 2008, gage height, 16.02 ft.
