Water levels below land surface are accurate to 0.01 feet. Water levels above North 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 plus-or-minus 0.3°C, and differences in temperature are accurate to 0.1°C.
