SURFACE-WATER RECORDS

PERIOD OF RECORD - April 1912 to September 1924, October 1926 to September 1927, October 1931 to June 2016 (discontinued). No winter records for river since 1972; no winter records for canal 1972 to 1996. Monthly discharge only for some periods, published in WSP 1310.

GAGE - River: Water-stage recorder and concrete control. Elevation of gage is 7,388.99 ft above NGVD of 1929. April 16 to November 15, 1912, nonrecording gage and November 16, 1912 to September 22, 1915, water-stage recorder 90 ft downstream from station between dam crest and canal headgates at datum 1.00 ft higher. September 23, 1915 to September 30, 1924, April 19 to September 30, 1927, and April ll, 1932 to September 30, 1935, water-stage recorder at site 50 ft downstream from station at datum 1.00 ft higher. October 1, 1935 to July 13, 1950, water-stage recorder at site 50 ft downstream from station at present datum. Canal: Water-stage recorder and Parshall flume. Elevation of gage is 7,390 ft above NGVD of 1929, from topographic map. April 16, 1912 to April 10, 1923, nonrecording gage; April 11, 1923 to September 30, 1924, and April 19 to June 9, 1927, water-stage recorder; June 10 to September 30, 1927, and April 11, 1932 to May 8, 1938, nonrecording gage; May 9, 1938 to April 26, 1966, water-stage recorder at site 1.5 mi downstream from station at different datums. April 27, 1966 to May 8, 1967, at present site, at datum 0.06 ft lower. From 2002 through 2010, water was diverted from the Laramie River by a City of Laramie pipeline upstream from the Pioneer Canal headgate and returned to the canal downstream from the flume. This diverted flow was added to the discharge record from 2002 through 2010. In 2011 the pipeline was rerouted and flow was no longer returned to Pioneer Canal. Flows from the pipeline are no longer included beginning in 2011. National Weather Service, in cooperation with Wyoming State Engineer's Office, has data collection platform with satellite telemetry at station.

COOPERATION - Station operated and record provided by the Wyoming State Engineer's Office; record reviewed by U.S. Geological Survey (discontinued June 2016).

Pioneer Canal diverts from left bank of river at diversion dam 100 ft downstream from station for 
irrigation in vicinity of Laramie. Records show combined flow of river and canal. Three small 
reservoirs upstream from station in Wyoming, total capacity, about 600 acre-ft for irrigation, stock 
water, and domestic use. Diversions for irrigation upstream from station. Transbasin diversions 
upstream from station to Cache la Poudre River and tributaries.
