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 during Dec. 20, 2011 at 17:00 CST to Oct. 24, 2013 at 11:00 CDT (measured with KPSI 500 transducer) were accurate to plus-or-minus 0.5°C, due to noisiness in the water temperature record and the use of an uncalibrated thermistor. Water temperatures during Oct. 24, 2013 at 12:00 CDT to the present (currently measured with Design Analysis H-310 transducer) are accurate to plus-or-minus 1.0°C, due to the use of an uncalibrated thermistor. Differences in temperature are accurate to 0.1°C.
