_________________________ADDITIONAL NOTES AND FINDINGS________________________


1) The Patch Test was performed on 02-28-2013 and 03-15-2013.
2) The Multibeam data was collected on 04-07,08,17-2013.
3) Laser data not submitted with this survey.
4) Due to a higher water surface elevation during the 2012 Revetment survey,
   there is a decrease in bankline coverage of approximately 2.5 foot.
5) There are no sunken objects located within the survey limits.
   
**The following note was established by a comparison of the 2013 Revetment
Bank to Bank Multibeam Survey to the 2012 Revetment Multibeam Survey**

6) There seems to be few areas of accretion and scour.
