Notes

Strongly flowing dark discharge around entrance & travelling south with some moving east along foreshore.

Beach is undulating with waves going further in low depressions (running north south), large amount of sand in back wash from these areas. Strong longshore drift across mouth.

Heavy local rainfall combined with higher falls in catchment (41 ml. recorded @ G6 -total since 15-10-2018) have greatly increased flow with river flushing strongly. Depth profile showed similar readings from top to bottom of water column at G5 & G4
