APPENDIX C: SURVEY DATA 

 Time History Graphs of Bottom Elevations (Figures CI and C2) 



1. Each graph shows how the bottom elevation varied throughout the year. 

 The vertical datum is National Geodetic Vertical Datum (NGVD) , and the hori- 

 zontal datum is the monumentation baseline. 



Contour Diagrams (Figures C3 through CI) 



2. Contour diagrams were constructed from the bathymetric survey data. 

 The profile lines surveyed are identified on each diagram. Contours are in 

 half meters referenced to NGVD.
