07119700 ARKANSAS RIVER AT CATLIN DAM NEAR FOWLER, CO
LOCATION.--Lat 38°07'33", long 103°54'41", in NE14NE14 sec.20, T.22 S., R.58 W., Otero County, Hydrologic Unit 11020005, on right bank at Catlin Canal flume gage, 2.2 mi downstream from diversion dam for Catlin Canal, 2.3 mi downstream from Apishapa River, and 6.0 mi east of Fowler.
DRAINAGE AREA.--10,901 mi2, of which 54 mi2 is probably noncontributing.
PERIOD OF RECORD.--October 1964 to current year. Statistical summary computed for 1975 to current year, subsequent to completion of Pueblo Reservoir. For a complete listing of historical data available for this site, see http://waterdata.usgs.gov/co/nwis/inventory/?site_no=07119700
GAGE.--Water-stage recorder with satellite telemetry on river; water-stage recorder with satellite telemetry and Parshall flume on Catlin Canal. Datum of gage on river is 4,245.92 ft and on canal is 4,257.87 ft above NGVD of 1929. Prior to May 13, 1971, gage on river at site 2.2 mi upstream at datum 24.08 ft higher, and gage on canal at site 1.7 mi upstream at datum 3.26 ft higher.
REMARKS.--Records good, except for estimated daily discharges, which are poor. Discharge computed by combining discharge of river downstream from canal with that of Catlin Canal. Natural flow of stream affected by storage reservoirs, power developments, transbasin and transmountain diversions, diversions for irrigation and municipal use, ground-water withdrawals, return flows from irrigated areas, and flows from sewage-treatment plants. Flow partly regulated by Pueblo Reservoir (station 07099350) about 69 mi upstream since Jan. 9, 1974.
COOPERATION.--Records collected and computed by Colorado Division of Water Resources and reviewed by Geological Survey.
a Average discharge for 9 years (water years 1965-73), 636 ft3/s, 460,800 acre-ft/yr, prior to completion of Pueblo Dam.
f Maximum discharge and gage height for period of record, 43,200 ft3/s, Jun 18, 1965, gage height, 7.95 ft, site and datum then in use, from rating curve extended above 13,000 ft3/s on basis of flow-over-dam computation of peak flow.
