Water-Year Summary for Site 07239450
10/01/2021 - 09/30/2022: records good.
Some regulation by Canton Lake (station 07238500).
Quality of data for other periods can be obtained by contacting the Oklahoma-Texas Water Science Center.
WATER TEMPERATURE: Water quality data only was collected between 1974 - 1975. The site was set up for stream gaging and water quality monitoring in October 1988 to current year.
SPECIFIC CONDUCTANCE: Water quality data only was collected between 1974 - 1975. The site was set up for stream gaging and water quality monitoring in October 1988 to current year.
pH: Water quality data only was collected between 1974 - 1975. The site was set up for stream gaging and water quality monitoring in October 1988 to current year.
DISSOLVED OXYGEN: Water quality data only was collected between 1974 - 1975. The site was set up for stream gaging and water quality monitoring in October 1988 to current year.
Accuracy rating of the record for the 2022 Water Year:
WATER TEMPERATURE: Good; No fouling or calibration corrections were applied per USGS water temperature policy. This sensor was not 5-point NIST checked within this water year. For this reason, the accuracy rating has been downgraded from "excellent" to "good".
SPECIFIC CONDUCTIVITY: Fair; Fouling and calibration drift corrections were applied throughout the year, most of which fell into the good rating with one period having large corrections that required MAL deletions. Because the temperature sensor was not NIST checked within the 2022 water year, this accuracy rating has been downgraded from "good" to "fair".
pH: Poor; Several fouling and calibration drift corrections were applied throughout the year, and minimal data gaps occurred. It was determined that multiple, poor calibrations had been applied in the field which led to large, required corrections throughout the year. Additionally, because the temperature sensor was not NIST checked within the 2022 water year, this accuracy rating has been classified as "poor".
DISSOLVED OXYGEN: Fair; Moderate fouling and calibration drift corrections were applied throughout the year, many of which fell within the good rating ranges. Some periods required large corrections that exceeded MAL, while other periods did not require corrections at all. Minimal data gaps occurred. Because the temperature sensor was not NIST checked within the 2022 water year, this accuracy rating has been downgraded from "good" to "fair".
