                                              WATER-QUALITY RECORDS

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

PERIOD OF DAILY RECORD.--
   SPECIFIC CONDUCTANCE:  April 1997 to September 1997, April 1998 to September 1998.
   WATER TEMPERATURE:  November 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 and specific conductance data
   from the in-situ probes often times did not exactly agree with the water temperature and specific conductance
   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 TEMPERATURE:  Maximum, 29.5`C, August 9, 1998; minimum, 0.0`C on many days during winter periods.

EXTREMES FOR CURRENT YEAR.--
   WATER TEMPERATURE:  Maximum, 29.5`C, August 9; minimum 0.0`C, on many days during winter period.

REMARKS.--The following data are for analytes from the National Water Quality laboratory (NWQL) schedule 2010--
   pesticides in filtered water.  Samples are filtered through a glass-fiber membrane filter with openings that
   are 0.7 microns in size to remove sediment and microorganisms.  A surrogate is then added to the sample.  The
   filtered water is field extracted on C-18 Solid Phase Extraction Cartridges and analyzed by a gas
   chromatography/mass spectrometric detector.
     The method detection limit (MDL) provides an index to indicate where measurement uncertainty is increased.
   When an analyte is detected and all criteria for a positive result are met, the concentration is reported.  If
   the concentration is less than the MDL, an 'E' code will be reported with the value.  If the analyte is
   qualitatively identified as present, but the quantitative determination is substantially more uncertain, the
   NWQL will identify the result with an 'E' code even though the measured value is greater than the MDL.  A value
   reported with an 'E' code should be used with caution.  When no analyte is detected in a sample, the default
   reporting value is the MDL preceded by a less-than sign (<).
   The abbreviations SRG, SURROGT, or SURROG indicate surrogate recovery in percent.

REMARKS.--The following data are for analytes from the National Water Quality laboratory (NWQL) schedule 2051--
   pesticides in filtered water.  Samples are filtered through a glass-fiber membrane filter with openings that
   are 0.7 microns in size to remove sediment and microorganisms.  A surrogate is then added to the sample. The
   filtered water is field extracted on a Carbopak B solid phase extraction cartridge and analyzed by high
   performance liquid chromatography.
     The method detection limit (MDL) provides an index to indicate where measurement uncertainty is increased.
   When an analyte is detected and all criteria for a positive result are met, the concentration is reported.  If
   the concentration is less than the MDL, an 'E' code willl be reported with the value.  If the analyte is
   qualitatively identified as present, but the quantitative determination is substantially more uncertain, the
   NWQL will identify the result with an 'E' code even though the measured value is greater than the MDL.  A value
   reported with an 'E' code should be used with caution.  When no analyte is detected in a sample, the default
   reporting value is the MDL preceded by a less-than sign (<).
   The abbreviations SRG, SURROGT, or SURROG indicate surrogate recovery in percent.

REMARKS.--The following data are for analytes from the National Water Quality laboratory (NWQL)
    schedule 79--organochlorine herbicides recoverable from whole water samples by gas chromatography/electron
    capture detector.  Samples are filtered through a glass-fiber membrane filter with openings that are 0.7
    microns in size to remove sediment and microorganisms.
     The method detection limit (MDL) provides an index to indicate where measurement uncertainty is
    increased.  When an analyte is detected and all criteria for a positive result are met, the concentration is
    reported.  If the concentration is less than the MDL, an 'E' code will be reported with the value.  If the
    analyte is qualitatively identified as present, but the quantitative determination is substantially more
    uncertain, the NWQL will identify the result with an 'E' code even though the measured value is greater than
    the MDL.  A value reported with an 'E' code should be used with caution.  When no analyte is detected in a

     The method detection limit (MDL) provides an index to indicate where measurement uncertainty is increased.
    When an analyte is detected and all criteria for a positive result are met, the concentration is reported.  If
    the concentration is less than the MDL, an 'E' code will be reported with the value.  If the analyte is
    qualitatively identified as present, but the quantitative determination is substantially more uncertain, the
    NWQL will identify the result with an 'E' code even though the measured value is greater than the MDL.  A
    value reported with an 'E' code should be used with caution.  When no analyte is detected in a sample, the
    default reporting value is the MDL preceded by a less-than sign (<).

                                              WATER-QUALITY RECORDS

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

PERIOD OF DAILY RECORD.--
   SPECIFIC CONDUCTANCE:  March 1997 to September 1997, March 1998 to July 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 and specific conductance
   data from the in-situ probes oftentimes did not exactly agree with the water temperature and specific
   conductance 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 TEMPERATURE:  Maximum, 29.5`C, July 18, 1997; minimum 0.0`C, many days during winter periods.

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.--The following data are for analytes from the National Water Quality laboratory (NWQL) schedule 2010--
   pesticides in filtered water.  Samples are filtered through a glass-fiber membrane filter with openings that
   are 0.7 microns in size to remove sediment and microorganisms. A surrogate is then added to the sample.  The
   filtered water is field extracted on C-18 Solid Phase Extraction Cartridges and analyzed by a gas
   chromatography/mass spectrometric detector.
     The method detection limit (MDL) provides an index to indicate where measurement uncertainty is increased.
   When an analyte is detected and all criteria for a positive result are met, the concentration is reported.  If
   the concentration is less than the MDL, an 'E' code will be reported with the value.  If the analyte is
   qualitatively identified as present, but the quantitative determination is substantially more uncertain, the
   NWQL will identify the result with an 'E' code even though the measured value is greater than the MDL.  A value
   reported with an 'E' code should be used with caution.  When no analyte is detected in a sample, the default
   reporting value is the MDL preceded by a less-than sign (<).
   The abbreviations SRG, SURROGT, or SURROG indicate surrogate recovery in percent.

REMARKS.--The following data are for analytes from the National Water Quality laboratory (NWQL) schedule 2051--
   pesticides in filtered water.  Samples are filtered through a glass-fiber membrane filter with openings that
   are 0.7 microns in size to remove sediment and microorganisms. A surrogate is then added to the sample. The
   filtered water is field extracted on Carbopak B solid phase extraction cartridge and analyzed by high
   performance liquid chromatography.
     The method detection limit (MDL) provides an index to indicate where measurement uncertainty is increased.
   When an analyte is detected and all criteria for a positive result are met, the concentration is reported.  If
   the concentration is less than the MDL, an 'E' code will be reported with the value.  If the analyte is
   qualitatively identified as present, but the quantitative determination is substantially more uncertain, the
   NWQL will identify the result with an 'E' code even though the measured value is greater than the MDL.  A value
   reported with an 'E' code should be used with caution.  When no analyte is detected in a sample, the default
   reporting value is the MDL preceded by a less-than sign (<).
     The abbreviations SRG, SURROGT, or SURROG indicate surrogate recovery in percent.
