Natural opening occurred over night. Strong outflow through a very wide entrance both at mouth & start of channel

AHD 1.09 @  08:52       0.86   @  10:36      0.82  @  11:37  

AHD G6  2.31  @ 08:38    

Waves pulsing from entrance to G2 but very strong flow downstream below 2.00m increasing with depth.   Weights & rope covered with dead veg. & coarse black silt

Similar conditions at Lt1 but too much drift on weighted rope / probe to monitor. Large amount of dead veg. in flow. Fish (about 10 -15 cm) trying to swim upstream  against flow

Fresh water inflow not possible to estimate, there seem to be currents crossing downstream but pulsing going upstream. (influence of barred mouth ??) Slight N wind about 2-3
