Alternate Title

The Impact of the 1973 Flooding of the Mobile River System on the Hydrography of Mobile Bay and East Mississippi Sound


Hydrographic conditions in lower Mobile Bay and East Mississippi Sound are documented during two flooding intervals of the Mobile River System. The flooding river waters so dominated Mobile Bay that a near limnetic system prevailed for over 30 days except in the deeper areas. East Mississippi Sound was also greatly influenced by river waters, but to a lesser extent than Mobile Bay. Dissolved oxygen concentrations were decreased in both locations as flooding progressed. No significant temperature differences between flooding, estuarine or Gulf of Mexico waters were observed.
