UPPER MISSISSIPPI RIVER BASIN


05420500       MISSISSIPPI RIVER AT CLINTON, IA

(National Stream-Quality Accounting Network Station)


LOCATION.-- Lat 41°46'50", long 90°15'07", in NW1/4 sec.34, T.81 N., R.6 E., Clinton County, Hydrologic Unit 07080101, on right bank at end of Eighth Avenue in Camanche, 5.0 mi upstream from Wapsipinicon River, 6.4 mi downstream from Clinton, 10.6 mi downstream from Lock and Dam 13, and at mile 511.8 upstream from Ohio River.

DRAINAGE AREA.-- 85,600 mi2, approximately, at Fulton-Lyons Bridge at Clinton.

PERIOD OF RECORD.--
SURFACE-WATER DISCHARGE AND STAGE
 

DISCHARGE: June to August 1873 (fragmentary), October 1873 to current year (October 1932 to September 1939, published as "at Le Claire")(June 1873 to December 1932 published in the Iowa State Planning Board report "Stream-flow records of Iowa, 1873-1932").
SURFACE-WATER QUALITY
 

CHEMICAL: October 1974 to September 1987, October 1994 to current.
 

SEDIMENT: October 1994 to September 30, 1997 (discontinued).
 

SPECIFIC CONDUCTANCE: July 1975 to September 1976; sporadic measurements February 1977 to September 1981; October 1994 to September 30, 1997 (discontinued).
 

WATER TEMPERATURE: July 1975 to April 1989; January 1995 to September 30, 1997 (discontinued).
 

MISCELLANEOUS: Periodic observations.

REVISED RECORDS.-- WDR IA-75-1: 1974.

GAGE.-- Water-stage recorder, U.S. Army Corps of Engineers satellite telemeter and rain gage. Datum of gage is 562.68 ft above sea level. June 6, 1969 to Sept. 16, 1988, water-stage recorder at site 400 ft. upstream at same datum. Auxiliary water-stage recorder at Lock and Dam 13 since Oct. 1, 1958. See WSP 1728 for history of changes prior to Oct. 1, 1955.

REMARKS.-- Minor flow regulation caused by navigation dams. During periods of ice effect, sediment samples are collected in open water channel. Records of specific conductance are obtained from suspended-sediment samples at time of analysis.

EXTREMES FOR PERIOD OF RECORD.--
SURFACE-WATER DISCHARGE AND STAGE: Maximum daily discharge, 307,000 ft3/s, discharge affected by regulation or diversion, April 28, 1965, gage height, 24.65 ft; minimum daily discharge, 6,500 ft3/s, December 25, 1933.

EXTREMES OUTSIDE PERIOD OF RECORD.--
SURFACE-WATER DISCHARGE AND STAGE: Maximum stage known since at least 1828, that of Apr. 28, 1965.
SUSPENDED-SEDIMENT CONCENTRATIONS: Maximum daily mean, 294 mg/L; Apr. 7, 1997; minimum daily mean, 1 mg/L several days in December 1995 - January 1996.
SUSPENDED-SEDIMENT LOADS: Maximum daily, 108,000 tons, Apr. 7, 1997; minimum daily, 96 tons, Jan. 9, 1996.
SPECIFIC CONDUCTANCE: Maximum daily 560 microsiemens Nov. 24 to Dec. 3, 1979; minimum daily 220 microsiemens Apr . 19, 20, 1976, Nov. 8-18, 1980.
WATER TEMPERATURE: Maximum daily 31.5°C July 21-23, 1983; minimum daily 0.0°C on many days during winter periods.
