Dive report: Million Bay

Jul 11, 2023
High tide 2:00pm
Sunny
10-15 knots but westerly and very calm
2hrs
4.6 m
Transect at 120° looking for Caulerpa
Vis 3-4 m

Two NNZD and a pair of VOC on Baddleys Beach as I got in the water. I walked through the water for about 100 meters then snorkelled further out into the bay. I nearly made it to the mouth of the bay (about 1km) before doing a surface swim back with 70 bar.

I was surprised by the great vis and healthy looking cockle bed. The seagrass condition was poor and I didn't see any fish larger than my fingers other than a snake eel whose hole was very shallow (2.1 m). It was sandy to about 3 m which is well out into the bay, which was very shallow. The crimson jellies seemed abundant for this time of year.
