Another afternoon low tidal flow and another dive in a wonderful river, thanks whoever put it there! On sight the bottom was heavily laden with silt. The number of species was low. Rain is coming. Despite that on we went.st when you think oh the same ole stuff a Gymnodoris is found with brown specks around the yellow spots. And then while searching the Fish Cage a bright pink Flabellina or Samla was recorded - new species!

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!
