G'day
The mouth may still be blown out in a southerly, how much depends on a few things. Good thing is you can cruise up the creek as far as you want and there's plenty of options.
Launching, forget lota unless its a reasonable high tide and your boat is 14' or less. Go down to the "ramp" alongside the train station at thorneside or the proper ramp further downstreem of there, it's marked in the ubd.
