WATER-QUALITY RECORDS

PERIOD OF RECORD - May 2019 to current year.

PERIOD OF DAILY RECORD -

WATER TEMPERATURE: May 2019 to current year.

SPECIFIC CONDUCTANCE: May 2019 to current year.

DISSOLVED OXYGEN: May 2019 to current year.

PH: May 2019 to current year

INSTRUMENTATION - This site is run using YSI EXO3 multiparameter sondes that are swapped between continuous monitor and field monitor approximately every two months. The sondes are calibrated in the Asheville Field office. Upon swapping the sondes calibration checks are completed within 24 hours of swapping sondes. All calibration techniques are derived from the USGS National Field Manual for the Collection of Water-Quality Data as well as manufacturer recommendations.

REMARKS - Station operated to define water-quality characteristics in the French Broad River Basin.
