DATUM - Land-surface datum is 916.09 ft above North American Vertical Datum of 1988. Measuring point: Transfer MP created for migration, 0 ft above land-surface datum, Apr. 13, 2016 to Jul. 16, 2020; Transfer MP created for migration, 7.2 ft above land-surface datum, Jul. 16, 2020 to present.

REMARKS - The record from 04/12/2016 to 04/18/2018 is poor based on 7 water level measurements made during the period to verify the data and is accurate to +/- 0.50 ft. The poor rating is due to large gaps in data and all but two of the measured water levels did not have any data transmitted to compare to. The record from 04/19/2018 to 12/25/2018 is good based on 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.05 ft. The record from 12/26/2018 to 04/16/2019 is good based on 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.10 ft. The record from 04/17/2019 to 09/16/2019 is good based on 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.10 ft.
