LOCATION.--Lat 39°24'37", long 106°14'57", in NW14SW14 sec.29, T.7 S., R.79 W., Eagle County, Hydrologic Unit 14010003, on right bank 0.9 mi upstream from Sheep Gulch, and 4.5 mi northwest of Climax.

DRAINAGE AREA.--7.78 mi2.

PERIOD OF RECORD.--June 2002 to current year. For a complete listing of historical data available for this site, see http://waterdata.usgs.gov/co/nwis/inventory/?site_no=09061600

GAGE.--Water-stage recorder with satellite telemetry and crest-stage gage. Elevation of gage is 10,000 ft above NGVD of 1929, from topographic map.

REMARKS.--Records good except for discharges above 45 ft3/s, which are fair, and estimated daily discharges and the period June 13-27, which are poor. Transbasin diversion upstream from station from Robinson Reservoir, (capacity 2,520 acre-ft) to Tenmile Creek for mining development. 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.
