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. The stage discharge relationship was affected by ice for certain hours of the following
days: December 24-26; January 6, 11, 12; February 10. The mean GH for these days was computed by
using the chart and chopping off the ice peaks. These days are considered to be “fair” discharges
since the majority of each day had good record. The record is rated as good, except for estimated
daily discharges, which are poor. The following days are considered as estimates due to possible
ice-effect: Dec. 24-26; jan. 6,11,12; Feb. 7-8, 10, 23-28; Mar. 1-3, 2003. Station maintained and
record developed by Robert E. Cooper.
