All the Suwannee River Basin USGS gages in Georgia just got a new flood level reporting system (except they missed one).
They’ve added a level measurement from sea level,
probably not coincidentally about the same as the Florida gages
added a level measurement from dry riverbed,
so both Georgia and Florida gages now have both measurements.
This actually does not affect the WWALS level charts for the
Withlacoochee and Little River Water Trail
nor for the
Alapaha River Water Trail,
because those continue to display water levels from dry riverbed.
To see this change at all, you have to drill down to the USGS detail pages,
for example on the Withlacoochee River
at Skipper Bridge Road in Georgia,
near Pinetta, Florida.
