PLATTE RIVER BASIN

06729500 SOUTH BOULDER CREEK NEAR ELDORADO SPRINGS, CO

LOCATION.--Lat 39°55'52", long 105°17'43", in SE¼ sec. 26, T.l S., R.71 W., Boulder County, Hydrologic
Unit 10190005, on left bank 0.2 mi downstream from South Draw, 1.0 mi west of Eldorado Springs, 1.8
mi downstream from South Boulder diversion canal, 5.0 mi south of Boulder, and 6.7 mi downstream
from Gross Reservoir.

DRAINAGE AREA.--109 mi².

GAGE.--Water-stage recorder with satellite telemetry and shaft encoder in metal box shelter with
supplemental outside chain gage. DCP is the primary record with chart recorder as backup.

REMARKS.--The record is good, except for the following days, which were estimated due to ice in well and on
control and are considered poor. December 23, 2001 – March 7, 2002. There was an artificially created
rock dam put in place by someone on August 16 between the gage and control, which created a higher pool
elevation and gave artificially high Gage Heights. This rock dam was removed on August 22 and a datum
correction of -0.17 was applied to this period of record. Station maintained and record developed by
M.L.Cunning.

RATING TABLE.--BOCELSCO22 USED FROM 01-OCT-2001 TO 24-OCT-2001
