PLATTE RIVER BASIN

06821360 ARIKAREE RIVER ABOVE SPRING CANYON NEAR IDALIA, CO

LOCATION.--Lat 39°45'07", long 102°24'42", in NW14SE14 sec.33, T.3 S., R.45 W., Yuma County, Hydrologic Unit 10250002, on right bank 1.2 mi upstream from Spring Canyon, 2.7 mi east of Rd U, 6.0 mi north of U.S. Hwy 36, and 5.0 mi northwest of Idalia.

DRAINAGE AREA.--1,111 mi2.

PERIOD OF RECORD.--August 2002 to September 2003 (discontinued). For a complete listing of historical data available for this site, see http://waterdata.usgs.gov/co/nwis/inventory/?site_no=06821360

GAGE.--Water-stage recorder with satellite telemetry. Elevation of gage is 3,820 ft above NGVD of 1929, from topographic map.

REMARKS.--Records fair except for estimated daily discharges, which are poor. Flow may be affected by irrigation well pumping throughout the basin upstream of the gage. Several measurements of specific conductance and water temperature were obtained and are published in the "Supplemental Water-Quality Data For Gaging Stations" section of this report.
