Knight Island Summary & Conclusions

• The area within the initial beach fill limits between DNR reference monuments R-27.5 and R-30.5 show signs of material spreading from the north end of the project towards the central and south ends.
• The most notable change in 1997 has been the continued volumetric gain at R-29 and R-30.   The southward spreading of the accreted material identified in the previous monitoring reports has continued and has now reached the southern end of the project, which was previously experiencing the highest losses.  The accretion at R-30 from 1997 to 1998 has reduced previous accumulated losses by more than half since the intial fill placement.
• Based on the comparison of the profiles between the January 1995, post construction survey and the most recent profiles collected in February 1998, there is more sand in the active littoral system within the beach fill limits today than following the initial beach fill placement.   The net gain is approximately 144,110 cubic yards, most of which is in the immediate nearshore region.  Between February 1997 and February 1998, there was a gain of approximately 28,755 cubic yards.
