Observation ID #13429
Date and Time Friday 22nd November 2019 11:45am

Dark discharge out mainly around the mouth -slight paler water along shoreline.

SW /WSW swell = occasional longshore drift to mouth creating small waves along east side of channel into the lagoon. Mid beach has 2 high areas of sand the most easterly one projecting out to sea. Waves going over this have created a small area of retained salt water further up the beach. Beach is undulating N/S with depressions allowing waves to go further up on beach & scour out sand with backwash

Sand on south side of lagoon well exposed extending far into lagoon. Separate sand bar closer to G2 is also exposed. The area on east side has a very large amount of green algae covering dying sea grass. Latrobe wetlands also has algae over most of the water
