The Ogeechee River arises in
the Georgia Piedmont, but the Coastal Plain contribues most to its flow.
It is a 'black water' river, carrying a high load of dissolved organic
carbon that imparts a 'tea' color to the water. Unlike other black water
rivers, the Ogeechee has a high pH (near 7.0) due to a large input of
carbonate-rich water from Magnolia Springs. Flow in the Ogeechee River
averages 100 cubic meters per second and the drainage basin covers
7,000 square kilometers.
