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.

13055000 TETON RIVER NEAR ST. ANTHONY, ID
LOCATION - Lat 43°55'38", long 111°36'50" referenced to North American Datum of 1983, in SW 1/4 SW 1/4 sec.15, T.7 N., R.41 E., Fremont County, ID, Hydrologic Unit 17040204, Newdale quad., on right bank 0.5 mi. upstream from railroad bridge, 4 mi. southeast of St. Anthony, and at mile 22.
DRAINAGE AREA - 876 mi².
REVISIONS HISTORY - 1997 (M)
SURFACE-WATER RECORDS
PERIOD OF RECORD - January 1890 to September 1893, April 1903 to June 1909, (irrigation seasons only 1920-21, 1923-33), April 1920 to May 1976 (destroyed by flood of June 5, 1976), October 1977 to current year. Monthly discharge only for some periods, published in WSP 1317. Published as "near Wilford" or "at Chases Ranch" 1890-93.
GAGE - Water-stage recorder and crest-stage gage. Datum of gage is 4,972.54 feet above NAVD 1988. Apr. 5, 1890 to Sept. 30, 1893, nonrecording gage at site 1 mi. downstream at different datum. Apr. 23, 1903 to June 30, 1909, non recording gage at site 0.8 mi. upstream at different datum. Apr. 19, 1920 to May 1, 1921, non recording gage, and May 2, 1921 to Nov. 5, 1933, water-stage recorder at site 400 ft. downstream at different datum. Nov. 6, 1933 to June 5, 1976, water-stage recorder at approximately same site at different datum.
REMARKS - Diversions above station for irrigation of about 58,000 acres of which about 4,400 acres are irrigated by withdrawals from ground water (1966 determination). Water is diverted at times (since 1939) during irrigation season from Henrys Fork through Cross Cut Canal to Teton River 0.8 mi. upstream from station.
EXTREMES FOR PERIOD OF RECORD - Maximum discharge, about 1,700,000 ft³/s, estimated from the average of slope-area measurements of peak flow at Teton, 5.3 mi downstream, and near Newdale, 3.4 mi upstream, June 5, 1976 (Teton Dam failure); maximum stage, 42.2 ft.
Maximum discharge excluding 1976, 11,000 ft³/s Feb. 12, 1962, gage height, 9.36 ft, on basis of contracted-opening measurement of peak flow, site and datum then in use. Minimum discharge, 103 ft³/s Oct. 4, 1975, gage height, 2.38 ft, site and datum then in use, due to filling of Teton Reservoir; minimum, excluding the filling period of Teton Reservoir, 203 ft³/s Jan. 13, 1983.
