Well, I've just been doing some sounding at the entrance to the Myall River. About three years ago the local council and state government spent $1.7mill dredging at Winda Woppa to open up the entrance to small boats and ferries. Now I recorded down to 0.6m depth, which is pretty much zero when corrected. Nature is hard to manipulate.

The Council spends $6.8 mill per year on its 26 sporting complexes, 3000 hectares of public land and cemeteries. That means that, annualised, the Council would spend about 5% of all it spends on sport and recreation on keeping just one channel open if it didn't get help from the state government (which pays half the cost). Even with the council spending 2.5% of its sport and rec. budget that still seems to be a disproportionate amount for something that is largely a convenience to a few boaties.

I know this example doesn't apply to many yachts, but it's something I was pondering when I was sounding the entrance today. The numbers for most dredging projects indicate that they represent an arguably disproportionate spend.

Top effort. As is known the Lower Myall River has two entrances each side of Corrie Island - which one did you sound?

Enormous history there obviously;

Dredging of the gut at Tea Gardens;

Good report here but only first 21 pages

And then there is the sand erosion at Jimmys Beach Winda Woppa - will continue on till the end of time................

What about Forster?I came thru there at high tide, 40ft cat it draws 66cm and bounced along the sand bank just past the bridge, that was a year ago and would be shallower now.Amaroo cruises couldn't get out to the ocean and have now sold their boat.Last time they dredged it, they piled the sand up at one spot which then slowly made it's way back into the river, also they were offered dredging for free as long as the operator could keep the sand and they refused the offer.
At the moment the only way to get my cat out is to go out on a full moon high but I'm doing a full refit so not going anywhere soon.

Same offer was made to Sutherland council re Port Hacking eons ago, same result and since then they have plowed millions into multiple half assed dredging attempts.

The problems at Forster started when they put in the small spur wall near the marina on the south side.
The whole sanding up problem can be sheeted home to that action.

And as to Lake Macquarie, when are they going to extend the training walls on the south side into the lake?

That would fix the problem for good and save a lot of money wasted on dredging!
