PROVISIONAL DATA SUBJECT TO REVISION
 
 
  STATION.--09416000 MUDDY RIVER NEAR MOAPA, NV
LOCATION.--Lat 36°42'40", long 114°41'40", in SE 1/4 SE 1/4 sec.15, T.14 S., R.65 E., Clark County, Hydrologic Unit 15010012, on left bank, 0.1 mi upstream from Battleship Wash, 0.8 mi downstream from Home Ranch, 5 mi northwest of Moapa, 9.5 mi upstream from Meadow Valley Wash, and 26 mi upstream from Lake Mead.
DRAINAGE AREA.--3,820 mi2, approximately, of which about 40 mi2 contributes directly to surface runoff.
PERIOD OF RECORD.--July 1913 to September 1915, April 1916 to September 1918, June 1928 to October 1931, April to July 1932, October 1944 to current year.
REVISED RECORDS.--WSP 1243: 1914 (M). WSP 1343: 1950 (M). WSP 1733: Drainage area.
GAGE.--Water-stage recorder and Cipolletti weir. Recording tipping bucket rain gage with 0.04 inch increment since December 1989. Elevation of gage is 1,710 ft above NGVD of 1929, from river-profile map. October 21, 1944, to September 30, 1948, water-stage recorder at datum 0.08 ft higher.
REMARKS.--Diversions for irrigation above station. Beginning October 1, 1976, records do not include part-time diversion about 100 ft upstream, for cooling of powerplants downstream. Normal flow originates from springs in reach 0.9 to 2.5 mi upstream from station. Flood peaks may be dampened by Arrow Canyon Dam.
EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, 5,760 ft3/s, August 16, 1990, gage height, 13.33 ft, on basis of slope-area measurement of peak flow; minimum daily, 19 ft3/s, October 10, 1997. Maximum daily precipitation, 2.12 inches, September 11, 1998.
FLOOD FORECAST.--NOAA, National Weather Service river forecast station accessed on September 11, 2003, at URL http://www.cbrfc.noaa.gov/river/station/flowplot/flowplot.cgi?MOAN2
