REMARKS -

Data from May 28, 2008 to November 01, 2009 is good based on 4 water level measurements made during this period to verify recorded water levels. The record from 11/02/2009 to 07/07/2010 is good based on 3 water level measurements made during the period to verify the record and is accurate to +/- 0.05 ft. The record from 07/07/2010 to 06/28/2011 is good based on 5 water level measurements made during the period to verify the record and is accurate to +/- 0.1 ft.This accuracy is a function of the pressure transducer. The record from 06/28/2011 to 08/16/2012 is good based on 4 water level measurements made during the period to verify the record and is accurate to +/- 0.1 ft. This accuracy is a function of the pressure transducer drift. The record from 08/17/2012 to 11/12/2013 is good based on 5 water level measurements made during the period to verify the record and is accurate to +/- 0.05 ft. The record from 11/13/2013 to 11/24/2014 is fair based on 2 water levels measurements made during the period to verify the recorded data and is accurate to +/- 0.10 ft. The record from 11/25/2014 to 07/26/2016 is good based on 4 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.10 ft. T he record from 07/27/2016 to 11/30/2016 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 11/31/2016 to 08/16/2017 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 08/17/2017 to 12/20/2017 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 12/21/2017 to 06/20/2018 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 06/21/2019 to 02/12/2019 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 02/13/2019 to 10/02/2019 is good based on 2 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.05 ft.
