06670500 LARAMIE RIVER NEAR FORT LARAMIE, WY
LOCATION - Lat 42°12'02", long 104°32'16" referenced to North American Datum of 1927, in NE 1/4 SE 1/4 NE 1/4 sec.28, T.26 N., R.64 W., Goshen County, WY, Hydrologic Unit 10180011, on right bank 600 ft upstream from bridge on county road, 0.6 mi upstream from mouth, and 1.1 mi southwest of Fort Laramie.
DRAINAGE AREA - 4,564 mi² of which 631 mi² probably is noncontributing.
REVISIONS HISTORY - WSP 1918: Drainage area.
SURFACE-WATER RECORDS
PERIOD OF RECORD - April 1915 to current year (no winter records prior to 1927). Monthly discharge only for some periods, published in WSP 1310. Records for water years 1926-39, previously published including diversions to Gering-Fort Laramie Canal, were adjusted to exclude flow in the canal in WSP 1310. Prior to October 1931, published as "at Fort Laramie". No diversion to Gering-Fort Laramie Canal since 1956.
GAGE - Water-stage recorder. Elevation of gage is 4,220 ft above NGVD of 1929, from topographic map. April 4, 1915 to March 31, 1925, nonrecording gage at site 0.1 mi downstream from station at different datum. April 1, 1925 to September 30, 1932, nonrecording gage and October 1, 1932 to August 20, 1935, water-stage recorder at site 4.3 mi upstream from station at different datum. August 21, 1935, to November 2, 1970, water-stage recorder at site 0.3 mi upstream from station at different datum. November 3, 1970 to May 9, 1973, water-stage recorder 0.1 mi downstream from station at different datum. May 10, 1973 to April 5, 1977, water-stage recorder 4.3 mi upstream from station at different datum. U.S. Army Corps of Engineers data collection platform with satellite telemetry at station.
