Species List: 21-01-2021, Toilet Block, La Balsa Park, Mooloolah River, Mooloolaba, Qld.

 24 species sighted at Toilet Block, La Balsa Park, Mooloolah River, Mooloolaba, Qld. 21-01-2021.

A single shore entry dive with Gary, Harvey and Tracey of 270 minutes. Maximum depth 6.7 m, 26 C water temperature, up to 6 m viz.

With a 1.3 m tidal flow we thought of giving Toilet Block another go. Upon arrival the river is finally getting brown. I knew this brown run-off was new and thought the bottom would be ok with a 1 m layer of fresh water on the surface. As we began our search it was clear the was the case. Oddly the numbers of species was low. It was nice quite a few Knoutsodonta maugeansis from under rocks. It was also a treat to see Diversidoris aurantionodulosa with it's egg mass... the future!

 40 species sighted at Fish Cage up river, La Balsa Park, Mooloolah River, Mooloolaba, Qld. 19-01-2021.

A single shore entry dive with Gary and Tracey of 310 minutes. Maximum depth 6.1 m, 27 C water temperature, up to 5 m viz.

Trying to get in as much as we can, with the potential of big rain coming. A 1.5 m tidal flow was very kind and very nice to search in. The first rock I turned over had one of favs - Knoutsodonta maugeansis while after 300 minutes of bliss I turned over my last rock and there it was my other fav - Limacia ornata! I am ok with happiness so please don't worry! Another great dive. Bob Burn has confirmed the Tornatina shell as a new species.
