That fishing area isn't anywhere near the replenishment area. Even so, things appear to be "booming". The marine life in the replenishment area have more to worry about like motors from boats and getting peed on from all the tourists.

Here is a 120 page environmental impact report to calm everyones nerves.

great tread. growing up on the west side, Waianae. I have always visted a beach called Pōka‘i bay. Long ago it was used as a boat ramp. To keep the ramp functioning they would have to remove sand on almost a yearly basis. seems the way the break water was built it cause the sand to deposit on the shore line. By removing the sand it kept the water at a comfortable depth. sardine, akule, oama would a school in the harbor. There was always fishermen trying to catch some very large and elusive mullet that frequent the bay. Swimming the bay you always saw "hawaii" a sea urchent the people ate right out of the water.

Pōka‘i bay had become inefficient that a new harbor (waianae small boat harbor) had been built. In doing so the sand had since accumulated and accumulated and...... accumulated. soo much sand that the water became to shallow for the marie life that once frequent the area. almost all of the marine life i used to see the is gone.

The break water that protects the harbor and been beaten by the hurricanes and looks worse for wear, yet it still provides safe harbor for those who chose swim there. As the sand accumulated it had since covered the boat ramps and piers along side it.

Swimmers who come to enjoy the calm waters, in doing so disturb sediment that may have accumulated over time. what was crystal clear water turns murky after the sediment is disturbed. I feel the sediment is partially run of from land as well as what people bring into the water with them.

I wonder if they tested the sand thats was pumped ashore? I know the shut beaches down because of run of from the alawai canal. some of which included human waste. I am thinking some of that run off became sediment and settled on/in the sands that they are pumping ashore?
I think if they some how followed the break water aspect of Pōka‘i they could have the same results as far sand replenishment. If one studies the way the current flows and makes the break water they can use mother nature to do the work.
the picture shows Pōka‘i bay from an arial point of view. the break water is to the bottom right extending from land to its left into the ocean. if you look at the picture there are to jetties extending from shore strait into the water. as you can see one side has more water then the other.... Hmm this tells you the way the currents run. The other photo of trees and some grass back when the used the place as a harbor. this area had no sand grass or trees I would say this place was about 3' deep with water. over time that how much sand had been deposited.
