I know Dave Mack has his detractors here but what do you think of his 'theory'? Seems to me there still is a turbidity issue.

How’s this for good news: Looking closer at the California regulations, there does remain a way for us to go down along the bottom of California’s waterways and suction up the shallower, higher-grade gravels. This is because, as defined by DFG’s own formal regulations, as long as we remove the sluice box from our motorized suction system, we are not operating a “suction dredge.”
I have outlined the initial concept on my blog at bit.ly/DaveMackBlog. Check it out!
