South bay surveys 



On 25 August, ADCP transect lines 1-10 in the south bay were monitored during flood 

 flow conditions (Plates A4 and A5). On 29 August, the south bay transect lines 4, 5, 7, 9, 

 and 10 (beginning 5 km south of the inlet and extending to the inlet) were monitored during 

 ebb flow conditions (Plates A17 and A 18). 



ICWW surveys 



On 25 August, ADCP transects in the ICWW were monitored during flood flow 

 conditions and slack conditions (Plates A5-A7). The transect lines are located in the area 

 between the confluences of the ICWW with the north and south bay channels and the 

 feeding channels behind the inlet. On 27 August, ICWW transect lines 13, 17, and 19 

 were repeated during flood flow conditions (Plates Al 1 and A 12). During this period, 

 longitudinal transects along the main channel and side channel center lines were also 

 monitored. 



Spring Tide Data Collection 



During the week of 15-19 September, the data collection effort was conducted for a 

 spring tide condition. The majority of the ADCP transect lines, monitored during the neap 

 tide period, were repeated for this data collection effort. For the spring tide measurements, 

 a greater priority was placed on obtaining data during periods of peak ebb and flood 

 currents. Additionally, the transect lines at the inlet (96), the entrance to the north bay 

 (30), and the entrance to the south bay (4) were repeated frequently in an effort to 

 determine current direction and magnitude both before and after each data set was 

 collected. Plate A22 identifies the locations for each area monitored during this spring tide 

 data collection period. On 15 September, ebb and flood flow conditions were monitored in 

 the south bay area. These data are summarized in Table A6, and the depth-averaged 

 velocity vectors are presented in Plates A23-A28. During the morning of 16 September, 

 transect lines on the ebb shoal were monitored for ebb flow conditions. These data are 

 summarized in Table A7, and the depth-averaged velocity vector plots are presented in 

 Plate A29. During the afternoon of 16 September, currents for ebb flow conditions were 

 monitored in the north bay area. These data are also summarized in Table A7, and the 

 depth-averaged velocity vector plots are presented in Plates A30-A33. Measurements on 

 17 September began on the ebb shoal during flood flow conditions. Afternoon 

 measurements, on this same day, were made on the ICWW during ebb flow conditions. 

 The data are summarized in Table A8 and plotted in Plates A34-A38. On 18 September, 

 an intensive 13-hr data collection effort was conducted in the inlet area. These data are 

 summarized in Table A9 but are not plotted. The data collection efforts for 19 September 

 were designed to cover transect lines located in areas of the north bay and the ICWW 

 during flood flow conditions. The data obtained for this period are summarized in 

 Table A 10, and velocity vector plots are presented in Plates A39-A42. 



The following is a detailed daily summary of the data collection effort conducted in the 

 respective areas during the period of the second trip (spring tide).
