PROVISIONAL DATA SUBJECT TO REVISION
Water levels below land surface (BLS) are accurate to ±0.01 feet;
differences are also accurate to ±0.01 feet. Water levels above the
North American Vertical Datum of 1988 (sea level) are calculated by
subtracting water levels, BLS from the land surface elevation (accuracy
is site-dependent).
Groundwater temperature is accurate to between ±0.1–1.0°C
depend on site; differences are accurate to ±0.1°C. Temperature is
depth-dependent. Therefore, temperatures at different depths are stored
in separate data sets, which specify the measurement depth.
Precipitation is accurate to ±0.01 inches except during freezing
periods (about December through early April). Rain gages are unheated
and uncovered. Precipitation recorded during freezing periods can be
caused by snow (previously accumulated in the rain gage) melting in the
gage funnel during warm periods and does NOT represent actual
precipitation at the time of recording. Precipitation recorded during
freezing periods likely underestimates actual precipitation because the
gage funnel may be full of snow (preventing further accumulation) or
because snow in the funnel may sublimate or blow out instead of melting
through the gage.

NOTE: During winter months, stage
and discharge may be significantly affected by backwater from ice,
resulting in incorrect discharge data. Consequently, discharge data may
not be displayed during periods of ice effect.
