                                              WATER-QUALITY RECORDS

PERIOD OF RECORD.--October 1996 to September 1998 (discontinued).

PERIOD OF DAILY RECORD.--
   WATER TEMPERATURE:  October 1996 to September 1998.

INSTRUMENTATION.--Daily record measured and collected at hourly intervals with in-situ probes and electronic data
   loggers.  Water temperature was measured and collected at hourly intervals using an in-situ probe with an
   electronic data logger.

REMARKS.--All water-quality samples were collected and analyzed by the U.S. Geological Survey.  Interruptions
   in the daily record were due to malfunctions of the equipment.  Water temperature data from the in-situ probes
   oftentimes did not exactly agree with the water temperature of the monthly and storm samples because of the
   fixed location of the in-situ temperature probes. Additional sites in the (NAWQA) fixed-station network are
   shown in figure 6 on page 28.  An explanation of selected abbreviations used in the water-quality tables are
   given on pages 29-31.

EXTREMES FOR PERIOD OF DAILY RECORD.--Maximum, 23.5`C, July 29, 1997; minimum, 0.0`C, many days during winter
   periods.

EXTREMES FOR CURRENT YEAR.--
   WATER TEMPERATURE:  Maximum, 22.5`C, June 26,29, August 5, 15; minimum, 0.0`C, many days during winter
   periods.

                                              WATER-QUALITY RECORDS

PERIOD OF RECORD.--February to October 1956, October 1959 to May 1973, December 1975 to August 1978, April 1996
   to September 1998 (discontinued).

PERIOD OF DAILY RECORD.--
   WATER TEMPERATURE:  October 1996 to September 1998.
   SUSPENDED SEDIMENT DISCHARGE:  October 1971 to September 1972.

INSTRUMENTATION.--Suspended-sediment samples were collected daily and more often during storm events
   by an observer from October 1971 to September 1972.  Water temperature was measured and collected at hourly  	
   intervals using an in-situ probe with an electronic data logger from October 1996 to September 1998.

REMARKS.--All water-quality samples were collected and analyzed by the U.S. Geological Survey.  Interruptions
   in the daily records were due to malfunctions of the equipment. Water temperature data from the in-situ probes
   oftentimes did not exactly agree with the water temperature of the monthly and storm samples because of the
   fixed location of the in-situ temperature probes. Additional sites in the (NAWQA) fixed-station network are
   shown in figure 6 on page 28.  An explanation of selected abbreviations used in the water-quality tables are
   given on pages 29-31.

EXTREMES FOR PERIOD OF DAILY RECORD.--
   WATER TEMPERATURE: Maximum, 28.0`C,June 25, 26 1998; minimum, 0.0`C, November 19, December 31, 1997,
   January 1, 2, 1998.
   SEDIMENT CONCENTRATIONS:  Maximum daily, 404 µg/L, June 24, 1972; minimum daily, 3 µg/L on several days during
   February 1972.
   SEDIMENT DISCHARGES:  Maximum daily, 10400 tons, June 24, 1972; minimum daily, 3.5 tons, September 11, 1972.

EXTREMES FOR CURRENT YEAR.--
   WATER TEMPERATURE:  Maximum, 28.0`C,June 25, 26 ; minimum, 0.0`C, November 19, December 31, January 1,2.

REMARKS.--Records good except for estimated daily discharges, which are fair.  Regulation by mine pumpage and
   reservoirs and diversion above station; the four largest reservoirs have a combined capacity of 42,360 acre-ft.
   Figures of daily discharge do not include diversion from Stonycreek River and Quemahoning Creek Reservoir to
   plants of Bethlehem Steel Co., and from Mill Creek, Dalton Run, and North Fork Bens Creek Reservoirs for water
   supply of city of Johnstown.  Several measurements of water temperature were made during the year.  U.S. Army
   Corps of Engineers satellite telemeter at station.

                                              WATER-QUALITY RECORDS

PERIOD OF RECORD.--October 1975 to September 1981, September 1992 to May 1994, April 1996 to September 1998
   (discontinued).

PERIOD OF DAILY RECORD.--
   SPECIFIC CONDUCTANCE:  July 1997 to September 1997, March 1998 to September 1998.
   pH:  July 1997 to September 1997, March 1998 to September 1998.
   WATER TEMPERATURE:  January 1978 to September 1979, November 1996 to September 1998.
   SUSPENDED SEDIMENT DISCHARGE:  February 1977 to September 1979.

INSTRUMENTATION.--From January 1978 to September 1979, water temperatures were once daily readings by an observer
   and suspended sediment samples were collected daily and more often during storm events by an observer.  From
   November 1996 to current year, daily records of water temperature, specific conductance and pH were measured
   and collected at hourly intervals with in-situ probes and electronic data loggers.

REMARKS.--All water-quality samples were collected and analyzed by the U.S. Geological Survey.  Interruptions in
   the daily record were due to frozen river conditions or malfunctions of the equipment.  Water temperature,
   specific conductance, and pH data from the in-situ probes often times did not exactly agree with the water
   temperature, specific conductance, and pH of the monthly and storm samples because of the fixed location of the
   in-situ probes.  Additional sites in the (NAWQA) fixed-station network are shown in figure 6 on page 28.  An
   explanation of selected abbreviations used in the water-quality tables are given on pages 29-31.

EXTREMES FOR PERIOD OF DAILY RECORD.--
   WATER TEMPERATURES:  Maximum, 27.5`C, July 3, 1997; minimum, 0.0`C, many days during winter period.
   SEDIMENT CONCENTRATIONS:  Maximum daily, 2,800 µg/L, June 17, 1978; minimum daily, 2 µg/L,
   September 9, 10, 11, 1978.
   SEDIMENT DISCHARGES:  Maximum daily, 20,900 tons, March 5, 1979; minimum daily, 0.44 ton,

REMARKS.--The following data are for trace elements and other constituents that were part of the suspended-
   sediment fraction of the water sample.  Suspended sediments were dewatered using a continuous flow centrifuge,
   dried, and analyzed directly for total metals using a nitric, hydrofluoric, perchloric acid digestion.  Whole
   water contributions by the suspended sediment were then calculated using the suspended-sediment concentration
   in kilograms per liter (kg/L) and the analyte concentration in milligrams per kilogram (µg/kg) from the direct
   analysis of the suspended sediments, resulting in micrograms per gram (mG/G) concentrations.  Values reported
   in percent are the percent of that constituent in the suspended sediment.  When no trace element was detected
   in the sample, the default reporting value is the method detection limit preceded by a less-than sign (<).

                                              WATER-QUALITY RECORDS

LOCATION.--Lat 40`33'52", long 79`46'22", Allegheny County, Hydrologic Unit 05010009, at New Kensington highway
   bridge, 5.1 mi downstream from dam at Lock 4 at Natrona, 5.3 mi downstream from gaging station at Natrona,
   and at mile 19.0 upstream from mouth.

DRAINAGE AREA.--11,500 mi2.

PERIOD OF RECORD.--July 1972 to December 1973, October 1974 to current year.

PERIOD OF DAILY RECORD.--
   SPECIFIC CONDUCTANCE:  October 1974 to September 1981.
   WATER TEMPERATURE:  October 1974 to September 1981 and October 1996 to September 1998.
   SUSPENDED SEDIMENT DISCHARGES:  October 1976 to September 1979.

INSTRUMENTATION.--From October 1974 to September 1981, specific conductance and water temperature were once daily
   readings by an observer.  From October 1976 to September 1979, suspended-sediment samples were collected
   daily and more often during storm events by an observer.  From October 1996 to current year, daily records of
   water temperature were measured and collected at hourly intervals with an in-situ probe and electronic
   data logger.

REMARKS.--Records of discharge are given for 03049500 Allegheny River at Natrona, Pa.  All water-quality samples 	
   were collected and analyzed by the U.S. Geological Survey.  Interruptions in the daily record were due to
   malfunctions of the equipment. Water temperature data from the in-situ probes often times did not exactly
   agree with the water temperature of the monthly and storm samples because of the fixed location of the in-situ
   temperature probes. Additional sites in the (NAWQA) fixed-station network are shown in figure 6 on page 28.
   An explanation of selected abbreviations used in the water-quality tables are given on pages 29-31.  Throughout
   the period of record, samples for this site have been collected at both the New Kensington highway bridge and
   the Hulton bridge in Oakmont (6.0 mi. downstream of the New Kensington highway bridge) due to factors such as
   bridge construction, highway detours, ice cover, etc.  From April 1996 to the current year, all samples have
   been collected at the Hulton bridge in Oakmont because this location is downstream of Deer Creek.  Deer Creek
   near Dorseyville, Pa., is an intensive fixed site for the NAWQA study unit.

EXTREMES FOR PERIOD OF DAILY RECORD.--
   SPECIFIC CONDUCTANCE:  Maximum, 440 micromhos, February 20, 1980; minimum 120 micromhos, March 11, 1979.
   WATER TEMPERATURE:  Maximum, 30.0`C, August 1, 2, 1975; minimum, 0.0`C, on many days during winter period.
   SEDIMENT CONCENTRATIONS: Maximum daily, 805 µg/L, January 2, 1979; minimum daily, 1 µg/L, August 4, 5, 1979.
   SEDIMENT DISCHARGES:  Maximum daily, 192,000 tons, January 2, 1979; minimum daily, 22 tons, August 5, 1979.

                                              WATER-QUALITY RECORDS

PERIOD OF RECORD.--October 1996 to September 1998 (discontinued).

PERIOD OF DAILY RECORD.--
   SPECIFIC CONDUCTANCE:  June 1997 to September 1998.
   pH:  June 1997 to August 1998.
   WATER TEMPERATURE:  October 1996 to September 1998.

INSTRUMENTATION.--Daily record measured and collected at hourly intervals with in-situ probes and electronic data
   loggers.  Water temperature was measured and collected at hourly intervals using an in-situ probe with an
   electronic data logger from October 1996 to September 1998.

REMARKS.--All water-quality samples were collected and analyzed by the U.S. Geological Survey.  Interruptions in
   the daily record were due to malfunctions of the equipment.  Water temperature, specific conductance, and pH
   data from the in-situ probes often times did not exactly agree with the water temperature, specific
   conductance, and pH of the monthly and storm samples because of the fixed location of the in-situ probes.
   Additional sites in the (NAWQA) fixed-station network are shown in figure 6 on page 28.  An explanation of
   selected abbreviations used in the water-quality tables are given on pages 29-31.

REMARKS.--The following data are for trace elements and other constituents that were part of the suspended-
   sediment fraction of the water sample.  Suspended sediments were dewatered using a continuous flow centrifuge,
   dried, and analyzed directly for total metals using a nitric, hydrofluoric, perchloric acid digestion.  Whole
   water contributions by the suspended sediment were then calculated using the suspended-sediment concentration
   in kilograms per liter (kg/L) and the analyte concentration in milligrams per kilogram (µg/kg) from the direct
   analysis of the suspended sediments, resulting in micrograms per gram (mG/G) concentrations.  Values reported
   in percent are the percent of that constituent in the suspended sediment.  When no trace element was detected
   in the sample, the default reporting value is the method detection limit preceded by a less-than sign (<).

                                              WATER-QUALITY RECORDS

PERIOD OF RECORD.--November 1975 to August 1981, April 1996 to September 1998 (discontinued).

PERIOD OF DAILY RECORD.--
   SPECIFIC CONDUCTANCE:  July 1997 to September 1998.
   pH:  July 1997 to September 1998.
   WATER TEMPERATURE:  October 1996 to September 1998.

INSTRUMENTATION.--Daily record measured and collected at hourly intervals with in-situ probes and electronic data
  loggers.  Water temperature was measured and collected at hourly intervals using an in-situ probe with an
   electronic data logger from October 1996 to September 1998.

REMARKS.--All water-quality samples were collected and analyzed by the U.S. Geological Survey.  Interruptions in
   the daily record were due to malfunctions of the equipment.  Water temperature, specific conductance, and pH
   data from the in-situ probes often times did not exactly agree with the water temperature, specific
   conductance, and pH of the monthly and storm samples because of the fixed location of the in-situ probes.
   Additional sites in the (NAWQA) fixed-station network are shown in figure 6 on page 28.  An explanation of
   selected abbreviations used in the water-quality tables are given on pages 29-31.

EXTREMES FOR CURRENT YEAR.--
   WATER TEMPERATURE:  Maximum, 28.0`C, July 22; minimum 0.0`C, on may days during winter period.

REMARKS.--The following data are for trace elements and other constituents that were part of the suspended-
   sediment fraction of the water sample.  Suspended sediments were dewatered using a continuous flow centrifuge,
   dried, and analyzed directly for total metals using a nitric, hydrofluoric, perchloric acid digestion.  Whole
   water contributions by the suspended sediment were then calculated using the suspended-sediment concentration
   in kilograms per liter (kg/L) and the analyte concentration in milligrams per kilogram (µg/kg) from the direct
   analysis of the suspended sediments, resulting in micrograms per gram (mG/G) concentrations.  Values reported
   in percent are the percent of that constituent in the suspended sediment.  When no trace element was detected
   in the sample, the default reporting value is the method detection limit preceded by a less-than sign (<).

                                              WATER-QUALITY RECORDS

PERIOD OF RECORD.--October 1947 to September 1950, October 1958 to September 1959, October 1968 to September 1972,
  November 1975 to September 1981, April 1996 to September 1998 (discontinued).

PERIOD OF DAILY RECORD.--
   WATER TEMPERATURE:  October 1996 to September 1998.

INSTRUMENTATION.--Daily record measured and collected at hourly intervals with an in-situ probe and electronic
   data logger.  Water temperature was measured and collected at hourly intervals using an in-situ probe with an
   electronic data logger from October 1996 to September 1998.

REMARKS.--All water-quality samples were collected and analyzed by the U.S. Geological Survey.  Interruptions
   in the daily record were due to malfunctions of the equipment.  Water temperature data from the in-situ probes
   oftentimes did not exactly agree with the water temperature of the monthly and storm samples because of the
   fixed location of the in-situ temperature probes.  Additional sites in the (NAWQA) fixed-station network are
   shown in figure 6 on page 28.  An explanation of selected abbreviations used in the water-quality tables are
   given on pages 29-31.

EXTREMES FOR CURRENT YEAR.--
   WATER TEMPERATURE:  Maximum, 28.5`C, August 9,10; minimum 0.0`C,December 31, January 1,2.

                                              WATER-QUALITY RECORDS

PERIOD OF RECORD.--October 1958 to September 1993 (discontinued). September 1994 to current year.

PERIOD OF DAILY RECORD.--
   SPECIFIC CONDUCTANCE:  January 1973 to October 1975.
   WATER TEMPERATURE:  January 1973 to September 1979, November 1996 to September 1998.
   SUSPENDED SEDIMENT DISCHARGE:  January 1973 to September 1979.

INSTRUMENTATION.--From January 1973 to September 1979, specific conductance and water temperature were once daily
   readings by an observer.  From January 1973 to September 1979, suspended-sediment samples were collected 	
   daily and more often during storm events by an observer.  From November 1996 to current year, daily records
   of water temperature were measured and collected at hourly intervals with an in-situ probe and electronic 	
   data logger.

REMARKS.--All water-quality samples were collected and analyzed by the U.S. Geological Survey.  Interruptions
   in the daily record were due to malfunctions of the equipment.  Water temperature data from the in-situ probes
   often times did not exactly agree with the water temperature of the monthly and storm samples because of the
   fixed location of the in-situ temperature probes.  Additional sites in the (NAWQA) fixed-station network are
   shown in figure 6 on page 28.  An explanation of selected abbreviations used in the water-quality tables are 	
   given on pages 29-31.

EXTREMES FOR PERIOD OF DAILY RECORD.--
   WATER TEMPERATURE:  Maximum, 30.0`C, on several days during the summer periods; minimum, 0.0`C, on several
   days each year before 1979 water year.
   SEDIMENT CONCENTRATIONS:  Maximum daily, 830 µg/L, March 15, 19, 1978; minimum daily, 2 µg/L,
   November 29, 1976.
   SEDIMENT DISCHARGES:  Maximum daily, 210,000 tons, January 12, 1974; minimum daily, 14 tons, February 8, 1977.
