The outage of the GOES-13 East satellite that occurred on May 22, 2013 which has kept some USGS Water Data current condition data from being updated is only affecting a few sites presently.
LOCATION.--Lat 43° 07'31", long 112° 31'08"
(NAD83), in SE1/4 SE1/4 sec.30, T.3 S., R.34 E., Bingham County,
Hydrologic Unit 17040206, Rockford quad., on right bank 0.3 mi
downstream from highway bridge, 0.7 mi downstream from Blackfoot
River, 10 mi southwest of Blackfoot, and at mile 750.1.
DRAINAGE AREA.--11,310 mi², approximately, excluding indeterminate
nontributary area on Snake River Plain.
PERIOD OF RECORD.--June 1910 to current year. Monthly discharge
only for some periods, published in WSP 1317. Published as "at
Clough ranch, near Blackfoot", 1924-45.
GAGE.--Water-stage recorder. Datum of gage is 4,399.83 ft above
NGVD of 1929. Prior to July 6, 1913, nonrecording gages; July 6, 1913
to Aug. 19, 1962, water-stage recorder at site 0.1 mi upstream at
datum 1.00 ft higher.
REMARKS.--Flow regulated by Jackson Lake, Palisades Reservoir,
Henrys Lake (sta 13039000), Grassy Lake, Island Park Reservoir, and
Blackfoot Reservoir (sta 13065000), having a combined capacity of
2,883,000 acre-ft. Diversions above station for irrigation of about
121,000 acres below and about 832,000 acres above station, 155,000
acres of which are irrigated by withdrawals from ground water (1966
determination). Considerable water leaks above the station into the
Snake River Plain aquifer.
EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, 53,500 ft³/s
June 7, 1976, gage height, 15.44 ft, result of Teton Dam failure.
Maximum discharge excluding 1976, 46,200 ft³/s June 18, 1918, gage
height, 14.80 ft, site and datum then in use; minimum, 111 ft³/s Nov.
10, 1934, gage height, 0.80 ft, site and datum then in use.
EXTREMES OUTSIDE PERIOD OF RECORD.--Late in summer of 1905 there
was no flow in Snake River for a distance of 10 mi in vicinity of
Blackfoot. Aug. 9, 1905, discharge of Snake River just below mouth of
Blackfoot was 39 ft³/s, supplied by ground-water inflow a short
