Notes
AHD @ G6 1.46
About 18 hrs. after artificial opening 10-3-18.
Very strong dark & dirty discharge carrying a large amount of sand down channel through very wide opening (18-20 m) cut in berm overnight. Outflow is going out to sea over a higher sand projection then turning east. Sides of cut about 3-4 m. high collapsing into fast flow. Flow level is higher at rocks then cascades down to lower level where sand is building up (or remaining) in front of 1st rock.The strong outflow is being crossed over by equally strong longshore drift at entrance, waves generated are entering channel
Several very small flounder were found stranded on lower part of berm., many sea birds 'fishing' in outflow. Large number of very small fish observed in shallow water at S/E corner of estuary
