Click to hide 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 2020
LOCATION - Lat 47°40'38.69", long 104°09'19.48" referenced to North American Datum of 1983, in SW 1/4 NE 1/4 SW 1/4 sec.09, T.22 N., R.59 E., Richland County, MT, Hydrologic Unit 10100004, on left bank at Montana-Dakota Utilities Company powerplant, 0.2 mi downstream from bridge on State Highway 23, 2.5 mi south of Sidney, 3.0 mi downstream from Fox Creek, and at river mile 29.2.
DRAINAGE AREA - 69,099 mi² of which 692 mi² probably is noncontributing. Area at site 4.5 mi upstream. 68,812 mi².
REVISIONS HISTORY - Water Data Report MT-04-1: Drainage area.
PERIOD OF RECORD - October 1910 to September 1931 (published as "at Intake"), October 1933 to current year. If monthly figures of diversions to Lower Yellowstone Canal at Intake are added to records at this site, records equivalent to those published as Yellowstone River at Glendive (1898-1910, 1931-34) can be obtained. Monthly discharge only for some periods, published in Water Supply Paper (WSP) 1309. Monthly figures of diversions into Lower Yellowstone Canal prior to 1951 published in WSP 1309, 1951-60 published in WSP 1729, 1961-65 published in WSP 1916, 1966-70 published in WSP 2116, and 1971 to current year are published in annual reports.
GAGE - Water-stage recorder. Elevation of gage is 1,881.3 ft, referenced to National Geodetic Vertical Datum of 1929, levels by U.S. Army Corps of Engineers. Jan. 1, 1911, to Sept. 30, 1931, nonrecording gage at site 32 miles upstream at different elevation. Apr. 9, 1934, water-stage recorder at two sites within 500 ft of highway bridge 0.2 mi upstream and May 17, 1945, to Apr. 3, 1952, nonrecording gage on same bridge at elevation 1.36 ft higher. Apr. 4, 1952, to Nov. 19, 1967, water-stage recorder at site 4.5 mi upstream at different elevation. U.S. Army Corps of Engineers satellite telemeter is located at the station.
10-01-2018 to 09-30-2019: records are good, except estimated records, which are poor.
10-01-2017 to 09-30-2018: records are good, except estimated records, which are poor.
10-01-2016 to 09-30-2017: records are good, except estimated records, which are poor.
10-01-2015 to 09-30-2016: records are good, except estimated records, which are poor.
10-01-2014 to 09-30-2015: records are good, except estimated records, which are poor. 
10-01-2013 to 09-30-2014: records are good, except estimated records, which are poor. 

Flow is regulated to some extent by Bighorn Lake, usable capacity, 1,312,000 acre-ft, on the Bighorn 
River and on other tributary streams in Wyoming and Montana. Diversion for irrigation of about 
1,250,000 acres occurs upstream from station. Lower Yellowstone Project Main Canal diverts from left 
bank in NW1/4 sec.36, T.18 N., R.56 E., at Lower Yellowstone diversion dam at Intake about 36.6 mi 
upstream for irrigation of about 52,000 acres of which about one-third lies upstream from station.
PERIOD OF RECORD - Water years 1948 to current year.
SPECIFIC CONDUCTANCE: October 1964 to September 1981. 
WATER TEMPERATURE: January 1951 to September 1985, May 2016 to current year (seasonal record). 
SUSPENDED-SEDIMENT DISCHARGE: October 1971 to September 1981, October 1982 to September 1991, 
seasonal records (March (or ice breakup) through November) from October 1991 to current year. 

WATER TEMPERATURE (seasonal record):
Records no longer rated
04-19-2018 to 10-31-2018: records are excellent.
04-04-2017 to 10-31-2017: records are excellent.
08-07-2016 to 08-21-2016, 09-04-2016 to 09-05-2016: records are fair.
05-09-2016 TO 08-06-2016, 08-22-2016 to 09-03-2016, 09-06-2016 to 09-30-2016: records are excellent.

Daily sediment records are rated good except for several periods of storm runoff, which are rated 
fair to poor. Daily sediment data collected seasonally (October 2011 through November 2011 and 
April 2012 through September 2012) during open water. Hydrologic events during summer months, when 
sampling frequency is reduced, were not sampled at an ideal frequency. All sample results were used 
in the construction of the sediment concentration curve. Suspended and bed sediment samples plus the 
seasonal daily sediment record were obtained as part of the Corps of Engineers program.



SPECIFIC CONDUCTANCE: Maximum daily, 1,220 microsiemens per centimeter (uS/cm) at 25.0°C, Apr. 6, 
1979; minimum daily, 261 uS/cm at 25.0°C, June 4, 1966. 
WATER TEMPERATURE: Maximum, 29.0°C July 23, 1960; minimum, 0.0°C on many days during winter. 
SEDIMENT CONCENTRATION: Maximum daily mean, 26,800 mg/L May 8, 1975; minimum daily mean, 8 mg/L 
Jan. 9, 1973. 
SEDIMENT LOAD: Maximum daily, 3,030,000 tons May 8, 1975; minimum daily, 63 tons Jan. 2, 1989. 
EXTREMES FOR CURRENT YEAR - SEDIMENT CONCENTRATION: During period of seasonal operation, maximum daily mean, 2,370 mg/L, June 8; minimum daily mean, 23 mg/L, Nov. 8 and Sep. 25-29. SEDIMENT LOAD: During period of seasonal operation, maximum daily, 233,000 tons, June 8-9; minimum daily, 136 tons, Sep. 3.
