PLATTE RIVER BASIN

06720000 CLEAR CREEK AT DERBY, CO

LOCATION.--Lat 39°49'42", long 104°57'30", in SW¼SW¼ sec. 36, T.2 S., R.68 W., Adams County, Hydrologic
Unit 10190004, on right bank 875 ft downstream from York Street bridge, 0.5 mi upstream from mouth,
and 2.5 mi west of Derby.

DRAINAGE AREA AND PERIOD OF RECORD.--575 mi²; 1927 to present.

GAGE.--Graphic water-stage recorder with satellite monitoring DCP with digital shaft encoder and Telemark
in a 60 inch corrugated metal shelter and well. Station at this datum since June 26, 1992. Primary
reference is by electric drop tape.

REMARKS.--The primary record is hourly satellite data and mean daily gage heights from the chart. Daily
maximum and minimum stages for the satellite record checked to within ± 0.02 with the chart. Where
DCP data was missing, data was entered hourly from the chart. The beaded cable slipped out of the
wheel on the Shaft Encoder May 14, during a rise in stage. The chart values were entered for this 4
hour period. The problem was corrected during a visit to the gage that same day. The record is
good. Station maintained and record developed by Brent Schantz.
