USGS Water-Year Summary 2024

0344878100 HOMINY CREEK NEAR WEST ASHEVILLE, NC

LOCATION - Lat 35°33'41", long 82°35'49" referenced to North American Datum of 1983, Buncombe County, NC, Hydrologic Unit 06010105,

DRAINAGE AREA - 104 mi².

REVISIONS HISTORY - Revised: Turbidity data above 1000 FNU for the period of 6/4/2019 to 9/18/2024 were revised on 5/28/2025 based on the creation of a new TBY.Censored time-series. Based on the manufacturers recommended sensor limits and the calibration standards used at this site the decision was made to censor all Turbidity values above 1000 FNU as the uncertainty in the value becomes higher.

SURFACE-WATER RECORDS

PERIOD OF RECORD - June 2019 to current year.

GAGE - Data collection platform. Datum of Gage is 1,975.32 ft. above NAVD of 1988. Satellite telemetry at site.

REMARKS - Gage-height records are generally good. Discharge records are generally good except for period of backwater conditions or estimated discharges, which are poor. Stage and discharge records are provisional August 3, 2021 to present while stage-discharge relationship is being reestablished. Additional details on the accuracy of the records can be obtained by contacting the USGS South Atlantic Water Science Center at gs-w-nc_nwisweb_data_inquiries@usgs.gov.

WATER-QUALITY RECORDS

PERIOD OF RECORD - June 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. 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.
