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 signific11nt temperature differences between flooding, estuarine or Gulf of M~xico waters were observed. During March, April, and May, 1973, coastal Alabama (Fig. 1) was subjected to two periods of flooding from the Mobile River System. Figure 2 presents the daily average discharges of the Mobile River System2 and illustrates the two flooding intervals. Utilizing Figures 32 and 33 in Pierce (1966), the first flooding period, with discharges of 9.5 x 103 m3 sec -1 , is classified as a five-year flood, while the second period, with a maximum discharge of 7.5 x 10 m3 sec -1, was of a magnitude equivalent to the mean annual flood. Recognizing the importance of understanding the impact that flooding of the Mobile River system has on Mobile Bay and Mississippi Sound, eleven hydrographic cruises were undertaken in these areas between April16 and May 15, ' Marine Environmental Sciences Consortium Contribution No. 020. 2 Mobile River System discharges are computed using 1973 U.S. Geological Survey Surface Water Records (Alabama) of the flows of the Tombigbee River at Coffeeville (02469761), Alabama, and of the Alabama River At Claiborne (02429500), Alabama. To calculate the discharge of the System, the flows at these two gauging stations are added together and multiplied by 1.07. Because of the distance between Mobile Bay and these gauging stations, a Jag period for transit time of five to nine days is needed. 68 1973 (Table 1 ). Specifically, the objective of these cruises was to document the extent of the river water influence on lower Mobile Bay and East Mississippi Sound. Previous studies provide a limited picture.
