PART III: HYDROGRAPHIC DATA 



5. The impact of the storm surge generated by Danny was minimal due to 

 the relatively low intensity of the hurricane and landfall being in a remote 

 and sparsely populated area of the Louisiana coastline. Moreover, much of the 

 reach of coastline affected by Danny is shallow swampland which tended to 

 dissipate the surge before it reached populated areas. Figures 2-4 show the 

 locations of hydrographs covering the reach of coastline from Cameron, La., to 

 the Rigolets near Slidell, La. Table 2 is the index to the tide gage loca- 

 tions. The hydrographs are contained in Plates 1-20. Table 3 is a listing of 

 the maximum water elevations recorded at each hydrograph location. 



6. Significant increases in water levels associated with the storm were 

 confined to approximately 60 miles of coastline extending westward from 

 Atchafalaya Bay to Pecan Island, La. These increases are evident in 



Plates 3-10, all of which were obtained within the previous reach of coast- 

 line. The highest water level recorded was 7.7 ft, relative to NGVD, which 

 occurred at Lukes Landing just north of Point Chevreuil, La. (Plate 7). Other 

 high-water levels were recorded at Vermilion Lock, east (7.1 ft, Plate 5), 

 Freshwater Bayou Lock (6.7 ft, Plate 3), and Atchafalaya Bay, Eugene Island 

 (6.7 ft, Plate 9).
