PLATTE RIVER BASIN

06711500 BEAR CREEK AT MOUTH, AT SHERIDAN, CO

LOCATION.--Lat 39°39'08", long 105°01'57", in NW¼NW¼ sec. 5, T,5 S., R.68 W., Arapahoe County, Hydrologic
Unit 10190002 on left bank just downstream from bridge on South Lowell Blvd., at Highway Department
maintenance building at northwest city limits of Sheridan, 1.3 mi upstream from mouth, and 2.l mi
west of city hall in Englewood.

DRAINAGE AREA AND PERIOD OF RECORD.--260 mi². April to Nov. 1914, March 1927 to current year. Monthly
data only prior to Oct. 1933.

GAGE.--Water-stage recorder with satellite telemetry, shaft encoder and Telemark in a 42-inch metal shelter
and well with supplemental outside wire weight gage.

REMARKS.--The primary record is hourly data from satellite with chart back-up. The data is complete and
reliable, except for the following days when the stage-discharge relationship was ice-affected:
January 19, 20, 23, 24, 25; February 10, 2002. A correction of –0.02 ft. occurred when the control
was cleaned of debris on the June 06 and October 15, 2002 measurements. The record is rated as
good, except for the following days which were estimated: January 19, 20, 23, 24, 25; and February
10. Computed flow came so close to zero this year that it is entirely possible to visualize a
condition where the only flow would be a small amount leaking under the control. The gage could not
accurately record a flow like this. Station maintained and record developed by Robert E. Cooper.
