re: Planned freshwater diversions will doom LA salt fishing

I'm in school for it and no I cannot

Is this the question you are talking about?

Call me crazy, but would it work any better to stir up a bunch of sediment via turbulence and then allowing it to go through a diversion? That way the top, skimmed stuff would have much more suspended sediment that just straight skimming off of the top?

There is a little more to it than just grabbing whatever sediment is available from the river bottom. The stuff you want to capture is the bedload. The bedload of the river is constantly changing and moving. As the flow of the river changes, large pockets of heavy sediment are moved around like dunes. During high river flows like the one we had a few years ago, the sediment carrying capacity of the river is sufficient to really move the bedload around and disperse it during flood stages.

Some areas of the river naturally accumulate large quantities of this good sediment, like bends. These areas can be used to strategically place diversions, or also be used as borrow areas for dredging that recharge naturally.
