Notes
AHD G2 0.50 AHD G6 1.00 @ 11:45
Outflow reducing - dark discharge only around entrance & south out to sea. Sand has built up in channel & at mouth. As a result of wave impact & recent short time swell times the beach has dramatically changed with very high /wide build up of sand projecting a long way out to sea from about 50m from entrance to east end.This build up has high front to sea & a large depression behind the front extending towards dunes. South west swell is impacting on start of projection & causing some longshore drift back to west across the mouth. The beach from the start of the projection to mouth is lower & has formed a bay
