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 only to ± 0.1 feet based on a differential
GPS survey and an optical level survey. Water-level differences are
accurate to within 0.01 feet.
Water temperatures are accurate to ± 0.1°C.
