PLATTE RIVER BASIN

06699005 TARRYALL CREEK AT BORDEN DITCH NEAR JEFFERSON, CO

LOCATION.--Lat. 39°17’13”, Long. 105°41’43”, in the NW ¼ of the NW ¼ of Sec. 8, T. 9 S., R. 74 W., Park County,
Hydrologic unit 10190001, on left bank 1800 ft. downstream from Rock Creek, 9 mi. southeast of Jefferson
and 1.0 mi. northwest of Bordenville.

DRAINAGE AREA AND PERIOD OF RECORD.--230 mi². Apr. 26, 1983 (no previous gage at this site). Operation
discontinued by USGS 9-30-97. Taken over by Colorado Division of Water Resources.

GAGE.--Shaft encoder and satellite monitoring DCP in a in a metal shelter on an 18-inch metal well. Well is
connected to stream by one 2-in. intake. Altitude of gage is 9020 ft, from USGS topographic map.
Station is maintained by the City of Aurora.

REMARKS.--Record is taken from hourly satellite readings and is complete and reliable, except for the following
periods: October 10-11, 2005, appeared to have ice in the stream; October 12, 2005 - April 11, 2006, when
the station was closed for winter; April 12, 2006 partial (start-up) day; April 13-20, 2006 showed
unusual gage height variations which could have been caused by ice in the stilling well; June 12-13,
2006, due to DCP failure; and, June 14, 2006 - July 18, 2006, when a single abnormally low gage height
value was recorded each day, which were considered to be erroneous and replaced with values obtained by
interpolation from adjacent good record, without loss in accuracy. The record is good for the entire
period of operation, except for October 10-11, 2005; April 12, and June 12-13, 2006 which are poor; and
April 13-20, 2006, which is fair. Station operated by Garver Brown and record developed by Garver Brown
and Russell Stroud.
