Figure 4-35. Channel elevation change, October 1990 to January 2002
A post-dredging condition survey following the recent dredging of
17-24 March 2004 was not available at the time of this writing. Figure 4-36
compares the shoreline of Mattituck Inlet of 16 April 2003 (11 months prior to
the most recent dredging) to the shoreline of 15 April 2004 (immediately after
dredging). The volume of 13,786 cu yd was removed from Mattituck Inlet and
the sediment was placed on the beach directly east of the inlet. The observed
morphology change clearly illustrates the placement of this sediment and
dredging of the main area of shoaling on the east bank, as well as the dredging of
the area of secondary shoaling in the west bank.
