PLATTE RIVER BASIN

06738100 CHARLES HANSEN FEEDER CANAL WASTEWAY TO BIG THOMPSON NEAR DRAKE, CO

LOCATION.--Lat 40°25'11", long 105°13'30", NE¼NW¼ sec. 10, T.5 N., R.70 W., Larimer County.

GAGE.--Graphic water-stage recorder with satellite telemetry in concrete shelter with supplemental outside
staff gage at 15' Parshall flume. Station maintained by N.C.W.C.D.

REMARKS.--The primary record is hourly DCP data with the graphic chart as backup. There were periods when
water was in the stilling well, causing a residual gage-height, which was entered as zero flow for
those periods. During the peak period (October 26-30) the DCP data bounced between a value that
agreed with the station visit & chart and a value that was 0.01 too low. A +0.01 correction was
applied to the individual hours that were low compared to the chart. Record is good. Station
maintained and record developed by Merlin Friedrichsen.
