PLATTE RIVER BASIN

WIND RIVER NEAR ESTES PARK, CO

LOCATION.--Lat 40º19’38”, long 105º34’53”

DRAINAGE AREA.--N/A

GAGE.--Graphic water-stage recorder with satellite telemetry in a wooden shelter with a concrete well and a
4’ Parshall flume. The electric drop tape is the primary reference. The DCP is the primary record
with chart backup. The Parshall flume and the well were replaced in August of 1995 due to extreme
settling over the years.

REMARKS.--The record is hourly satellite data with chart back up. It is complete and reliable except for
the following days: November 4, 2002 thru April 28 ,2003: Closed for winter; October 30, 31;
November 3, 4: Stage discharge relationship affected by ice. Satellite data GH’s agreed with chart
data to within +-0.02 except for periods in September when the chart recorder showed unexplained
drift. This is a partial year record station operated as part of the Colorado Big Thompson Project.
The record is good, except for October 30, 31 and November 3, 4 which were estimated. Stream flows
are affected by diversions above the station amounting to approximately 300 AF per water year.
Station maintained and record developed by Merlin Friedrichsen.
