Notes:
(1) CLF-UD location is the transducer installed in the underdrain sump side slope riser. The groundwater elevation is the average elevation from the entire transducer record on that
date.
(2) CLF21-14 was not replaced but the casing was adjusted in April 2022.
(3) Depth to water measurement for CLF21-10 was collected on 8/10/2021.
(4) The underdrain sump's construction dewatering pump was replaced with the temporary pump on 11/16/21.
(5) Depth to water measurement for CLF21-14 was collected on 1/14/2022.
(6) Location CLF-UD was inadvertently missed during the 7/7/2022 and 7/8/2022 gaging event. Data will be collected from the transducer at the end of the Q3 Quarter, corresponding with
a full water level gaging event for the ILF monitoring locations.
(7) Depth to water measurements for CLF-301, CLF-304, CLF-402, and CLF22-307 were collected on 10/12/2022; underdrain groundwater elevation is from 10/12/2022.
(8) Underdrain groundwater elevation is from 11/15/2022.
(9) Underdrain groundwater elevation is from 01/10/2023.
