Water levels below land surface are accurate to 0.01 feet. Water levels above National American Vertical Datum of 1988 (sea level) are calculated by subtracting recorded water levels from the land surface elevation, which is accurate to ± 0.01 feet based on a differential GPS survey. Water-level differences are accurate to within 0.01 feet.
Water temperature is accurate to ±0.3°C during 31 May 2019 to the present (measured with KPSI 500 transducer), due to moisiness in the water temperature record. Differences in temperature is accurate to 0.3°C. Water temperature were accurate to ±0.3°C during 23 May 2014 to 30 May 2019 (measured with KPSI 500 transducer), due to noisiness in the water temperature record. Differences in temperature were accurate to 0.3°C.
