USGS Water-Year Summary 2023

02187010 HARTWELL LAKE NEAR ANDERSON, SC

LOCATION - Lat 34°30'30", long 82°51'19" referenced to North American Datum of 1983, Anderson County, SC, Hydrologic Unit 03060103, at Hattons Ford Rd bridge crossing, 1.0 mi south of I-85 and 1.5 mi west of SC Highway 24.

DRAINAGE AREA - 2,088 mi².

REVISIONS HISTORY -

Relative humidity analysis in RMS updated on 01/15/2021 to the following:

08/08/2019 to 10/15/2019

The humidity sensor has been collecting erroneous data intermittently throughout the period, as noted in DCT. A threshold suppression removed all data greater than 100%. Spikes that exceed this threshold began occurring on August 19 and occurred frequently through the rest of the analysis period.

10/15/2019 to 12/09/2019

12/09/2019 to 03/10/2020

The humidity sensor has been collecting erroneous data intermittently throughout the period, as noted in DCT. A threshold suppression removed all data greater than 100%. Spikes that exceed this threshold occurred throughout the period, as listed in DCT. Sensor appears to be collecting less erroneous data than in previous periods.

03/10/2020 to 06/17/2020

The humidity sensor has been collecting erroneous data intermittently throughout the period, mostly from 03/19/2020 to 05/06/2020. A threshold suppression removed all data greater than 100%. Spikes that exceed this threshold occurred throughout the period, as listed in DCT. After 05/06/2020, the sensor began producing better quality data.
