12 | 26-Aug | 16:30 | 81 | 25 | 3.0 | 3 | 3 | Brown | 85% surface coverage (coontail).  Difficult to gain access into sampling area.
13 | 2-Sep | 15:30 | 82 | | | | | | Unable to access sample area due to 100% vegetation surface coverage beyond bridge.
14 | 9-Sep | 17:30 | 74 | 18.4 | 4.0 | 2 | 2 | Brown | 50% surface covered by vegetation
15 | 15-Sep | 16:45 | 82 | 20.6 | 5.0 | 2 | 2 | Brown | Lots of weeds just below surface, reducing navigation; 35% surface coverage
