Descriptive Information

Station Type Streamgage, continuous record Location Lat 43°37'15.2", long 110°37'23" referenced to North American Datum of 1983, in NW 1/4 sec.11, T.42 N., R.115 W., Teton County, WY, Hydrologic Unit 17040102, 3 mi below Turpin Creek and 0.3 mi south of Kelly, WY.

Gage Water-stage recorder. Elevation of gage is 6,660 ft above NGVD of 1929, from topographic map. June 16 to September 30, 1918, staff gage at site 1.2 mi upstream at different datum.

October 1, 1944 to August 8, 1949, wire-weight gage on bridge 280 ft upstream at different datum. August 9, 1949 to June 25, 1953, staff gage 315 ft upstream at different datum. May 15 to July 23, 1954, May 22 to June 28, 1955, supplementary staff gage 5 ft upstream at datum different, and May 20 1956 to July 10, 1958, supplementary staff gage at site 5 ft upstream at datum at different datum. July 10 to September 30, 1958, staff gage at site 305 ft upstream at different datum. U.S. Geological Survey data collection platform with satellite telemetry at station.

Regulation and Diversions Diversion dam structure has been removed as of March 2013. Ditch on right side of channel 600ft downstream of gage is now defunct.
