WATER-QUALITY RECORDS

PERIOD OF RECORD - May 23, 2016 to June 20, 2017.

INSTRUMENTATION - 2-inch diameter Eureka Manta 2 equipped with water temperature, specific conductance, pH, and optical dissolved oxygen connected to a Campbell Scientific CR10X datalogger.

REMARKS - Water year 2017 data quality assessment: Quality of daily records for water temperature is excellent; quality of daily records for specific conductance is excellent, except for the period of 2017/01/05 to 2017/02/03 which is rated good; quality of records for pH is good, except for the period of 2017/04/09 to 2017/06/20 which is fair; and quality of records for dissolved oxygen are excellent except for the daily ranges 2016/12/01 to 2016/12/02, 2016/12/18, 2016/12/28 to 2017/01/22, 2017/01/25 to 2017/01/26, 2017/04/05 to 2017/04/10, and 2017/04/27 to 2017/04/29 which are rated good, 2017/01/23 to 2017/01/24, 2017/01/27 to 2017/02/03, 2017/04/11 to 2017/04/16, and 2017/04/30 to 2017/05/07 which are rate fair, and 2017/04/17 to 2017/04/21 and 2017/05/08 to 2017/06/20 which are rated poor. Water year 2016 data quality assessment: Quality of daily records for water temperature and specific conductance is excellent; quality of records for pH for the daily ranges 2016/05/24 to 2016/07/09 and 2016/09/19 to 2016/09/30 is excellent; otherwise quality of daily records for pH is good; and quality of records for dissolved oxygen for the daily ranges 2016/05/24 to 2016/07/09 and 2016/09/19 to 2016/09/30 is excellent; otherwise quality of daily records is good.
