Notes
AHD G6 3.24 @ 14:28
Very dark strong discharge out around the mouth for about 100 m. also continuing a long way to the east along the shoreline. Eastern end of beach covered with dark silt. The strong outflow has created sheer east side to channel about 1 m. high above water level (87 ml rain @ G6 over past 8 days). Beach is undulating & scouring areas especially at mid beach where backwash is taking out a lot of sand -waves in all directions at this area creating occasional longshore drift across mouth. Large amount of sand build up remains downstream of rocks but is being covered by outflow & entering waves. More erosion on east face of Pt. Ronald.
Large areas of deep flood water covering large areas from G4 & G5 (also some between G5 &G6) but very little downstream G4. OOR only had slight flow across near flood markers (run off only.
