Water-Year Summary for Site 435723092171801
Water temperature: On 04 Dec. 2023, a +0.3°C shift was applied to all previously approved water temperature (21.9 ft. BLS) data during 20 Sept. 2018 at 21:00 CDT to 11 Apr. 2023 at 07:30 CDT. This shift was applied because for two reasons. First, there was a 1-pt calibration check on 23 Nov. 2022, which showed evidence the water temperature data collected during this period were inaccurately low by 0.3°C. Secondly, it was discovered after the transducer thermistor replacement on 08 Jun. 2023 that the previously approved water temperature data should be adjusted by +0.3°C to match the current transducer thermistor, which recently had a 3-pt calibration check.
Water temperature: On 12 April 2023, it was discovered that previously published (approved) water temperature (21.9 ft. BLS) were inaccurately corrected during 20 September 2018 to 20 October 2022. These previously published data were adjusted by -1.0°C during this period.
The hole for well WLN10 was drilled with an 12-inch-diameter and 8-inch diameter, rotary drill rig to a depth of 80 feet. The well is constructed of 18 feet of 4-inch-diameter, schedule-40 steel well casing. The casing measuring point (stickup) was 1.85 feet above land surface when measured on 21 Sept. 2016. The open interval (open hole) of the well is between 18 and 80 feet below land surface and the well is 80 feet deep.
NOTE: A total well depth of 99.15 ft. BLS was measured on 20 Sept. 2018 after pumping the well. The values above were recorded from the driller's log, which may be inaccurate according to this total well depth measurement.
Water levels were recorded periodically from 25 October 2016 to the present. Water levels were recorded hourly from 25 October 2016 at 14:00 CDT to 17 February 2017 at 08:00 CST.

23 Aug. 2017 at 08:15 CDT - 07 Oct. 2017 at 2:45 CDT: due to transducer hanging in air; WL dropped below bottom of transducer.
10 Nov. 2017 at 09:30 CST - 17 Jan. 2018 at 12:45 CST: due to transducer hanging in air; WL dropped below bottom of transducer.
17 Jul. 2018 at 13:45 CDT - 18 Jul. 2018 at 01:00 CDT: due to unknown pressure transducer recording issue.
30 Aug. 2018 at 15:00 CDT - 31 Aug. 2018 at 01:45 CDT: due to unknown pressure transducer recording issue.
10 Apr. 2019 at 22:45 CDT - 11 Apr. 2019 at 09:15 CDT: due to datalogger over-writing data and not downloading soon-enough.
25 Oct. 2019 at 08:45-14:45 CDT: due to removing transducer from well during attempted WQ sampling.
Intermittent gaps: 01 Jun. 2023 at 05:15 CDT - 06 Jun. 16:00 CDT: due to periodic transducer failures.
27 Sept. 2023 at 14:30 CDT - 28 Sept. 2023 at 04:45 CDT: due to removing transducer and pumping well during WQ sampling.
Highest instantaneous water level: 0.45 ft. below land-surface datum on 19 July 2019.
Lowest instantaneous water level: 15.74 ft below land-surface datum on 13 December 2022.

Lowest manual (discrete) water level: 15.11 ft below land-surface datum on 22 February 2018.
Precipitation were recorded quarter-hourly from 20 September 2018 at 18:00 CDT to the present, except during the following periods with gaps longer than 60 minutes:
10 Apr. 2019 at 22:45 CDT - 11 Apr. 2019 at 09:15 CDT: due to datalogger over-writing data and not downloading soon enough.
