Figure 27. Bathymetry at St. Paul Harbor, July 1995 



of its old location with accretion observed. Accretion of 1 .8 m (6 ft) had occurred at 

 the seaward head of the detached breakwater. Cut and fill inside the harbor north of 

 the TDX dock was probably related to the dredging operations at West Landing by 

 local interests. 



In an effort to better quantify scour and fill conditions at the harbor entrance, 

 two areas were selected for more detailed analysis. Figure 29 presents the areas 

 identified. Area A consists of 15,500 sq m (166,800 sq ft) and was initially used to 

 determine scour adjacent to the head of the breakwater extension; Area B includes 

 1 1 ,770 sq m (125,700 sq ft) and was used to depict accretion across a portion of the 

 entrance. Detailed bathymetry (0.3-m (1-ft) intervals) for Areas A and B are shown 

 in Figures 30 through 32 for the 1986, 1992, and 1995 surveys, respectively; and
