PLATTE RIVER BASIN

06708000 SOUTH PLATTE RIVER AT WATERTON, CO

LOCATION.--Lat 39°29'18", long 105°05'32", in NE¼ sec. 34, T.6 S., R.69 W., Jefferson County, Hydrologic
Unit 10190002, on left bank 168 ft downstream from bridge on State Highway 221, 0.4 mi south of
Waterton, 4.7 mi west of Louviers, and 6 mi upstream from Plum Creek.

DRAINAGE AREA AND PERIOD OF RECORD.--2,621 mi²; 1926 to present.

GAGE.--Graphic stage recorder, and satellite monitoring DCP with a phone modem (on separate floats)-- in a
60” galvanized, corrugated steel shelter and well. The primary reference is an electric drop tape.
Datum of gage 5,484.43 ft National Geodetic Vertical Datum.

REMARKS.--The primary record is hourly data taken from satellite monitoring with chart back up. The record
is complete and reliable except for December 22-25; February 24, 25; and March 18 when ice could
have accumulated on the control and in the well. The record is rated good except December 22-25;
February 24, 25; and March 18 which were estimated and poor. Denver’s attempt to maintain 15 cfs
during certain periods at the Waterton gage was complicated by ice conditions and the need for
better definition of the rating at this low flow. Station was maintained and record was developed
by R.E.Cooper.
