This morning and 11:30 either side of Semaphore jetty down to Point Malcolm looked ok - water surprisingly 'clean'. Lots of dry weed mounds at high tide mark though.
But from Pt Malcolm going way south to Tennyson ...20-30m of very smelly, black soup
Once the SW kicks in, it'll all move back to Sems, and dodge tide tomorrow too so I don't think it'll be going away in a hurry.
