Species List: 18-01-2020, Rotunda upriver, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld.

22 species sighted at Rotunda upriver, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld. 18-01-2020.

A single shore entry dive by Gary, Fran and Never of 178 minutes. Maximum depth 5.7 m, 27 C water temperature and up to 4m viz.

I got caught on the motorway to Mooloolaba in a massive stopped traffic jam. What would take 12-15 minutes took 1 hour and 35 minutes, which included me driving over a median strip to go back and take the exit to Kawana and then to the river....whew. After the dive I had a flat battery and had to call roadside assist. After some heavy all night rain the river was a little worse for wear. Finding the third Embletonia gracilis was a treat for me. Also great to see where the numbers of Myja sp. 1.
