They used to be on fire. Unfortunately, almost all the reefs in that area are silted over.


The reason all the reefs are silted over and the oysters aren't reproducing is because of the high salinity and water flow down there due to erosion.

This project is a good thing. It wants to restore the areas south like "washout" and "super cut" and "long point" back to how they were with just small cuts that allowed the water to flow through those points, instead of being wide arse open now due to erosion.

I still don't think it ever happens due to funding, which is why I've tried to encourage CCA to use artificial reefs to make rock piles down that area to help with the water flow. So we shall see....meanwhile the fishing has gone to crap because of it.

I sure hope you are wrong about this. It would be a shame to let that beautiful resource continue to decline. Hopefully they restore the areas you mentioned, at a minimum. I would also push for restoring the pass at Turner's Bay. I remember when the island was huge and the land on either side wasn't washed out.

I was reading the other night and found an article saying the ideal salinity for oyster growth was somewhere between 10 and 20ppt. Right now the lake is at 16ppt. So I don't think the high salinity is the problem, not that I have a very educated opinion. Maybe its the extreme fluctuation the lake has had over the past years with all of the spring rains?

I would say that the dredging in the ship channel and harvesting oysters using dredging methods are what decimated the populations. I am sure erosion is also a factor in that.

Definitely support a rock wall around the Washout/Long Point area though.
