98. Current meters at Site 2 would be heavily influenced by the 

 residual TGI - TG3 . Figure 12 shows the correlation regarding the directions 

 and timing of reversals for currents at site CM2S. At 1700 hr on 7 August, 

 the residual abruptly switched from positive to negative; the current switched 

 from inbound to outbound at the same hour and increased in magnitude to a max- 

 imum 8 hr later, when the residual reached its minimum of -0.4 ft. 



99. Examination of the three vector plots at Site 2 plainly shows that 

 more water flowed out of the channel here than flowed in, particularly at the 

 surface and middepth (Plates 24-26). This verifies the trend illustrated sta- 

 tistically in the rose plot. 



100. A similar look at residual TG6 - TG3 (Plate 27) shows even better 

 agreement with the meter at site 3 for all depths (Plates 28-30). At 0000 hr 

 on 8 August, all three meters had peaked in their outward flow and had begun 

 reversing inward after the peak (negative) residual. Similar correlation was 

 maintained over the 2 -day interval, but not without some phase shifts verti- 

 cally. The trend of meter CM3S toward the southeast and of meter 3B to the
