    Anyone know anything about coastal dredging?  Specifically, is it legal, and how do you go about estimating the required capital investment.  Even more specifically, the area I'm thinking about (and I'll tell you, cause I know I'll never be the one to dredge it) is "False Klamath Cove, California".  I thought that I once read, though I can't find the source now, that this was once the mouth of the Klamath river.  Certainly you only have to look at a topo map to see that this is possible.  If I were to do coastal dredging I would choose this spot because the Klamath is a known gold bearing stream, and since the river no longer flows here, none of the river stakeholders (fishermen, Native Americans, tourists,  environmentalists, etc.) are likely to give you a hard time.   Of course I don't know that there's any gold there, but right now this is just a thought experiment, so nothing can be lost but time.

    Just in round figures $1000000 + to set it up proper

    One of the better Bearing Sea dredge setups with decent equipment was $1000000 +
    Nice strong diesel engine with two sluices, nice crew quarters
    Of course that's in Nome where everything is expensive, although I don't believe it was built in Alaska
    Plus all the dive gear and other stuff

    To do it right aint gonna be cheap no matter where you build it

    The first thing you should do is go ask the fish and game if they will give you a special permit to dredge there and if so how much. and the rogue river has gold that where all the gold at gold beach come from I bet, I wood start about a thousand feet off shore of the Klamath River and test and get closer to shore each time and use a 8" or 10" or 12" blow off tube to get rid of all the fluff and use a small dredge to sample the hard pack and bed rock to see if there is any gold. I do believe that the gold moves south down the shore over time and I don't know which way the mouth moves north or south and was there any gold in the river at any given time period there is gold in the Klamath River now but if you go back in time, there may not be any gold in the river. I'm designing a deep sea gold dredge in my Maya program, I should be using AutoCAD. The dredge will be 100ft long and 50ft wide and it will use a crane with a clam shell bucket so it can go deep where no one has gone before and it might cost 1.5m to 2m. the crane could be 300k to 500k and I think Nome wood be the best place to put it. and that is if I wind 2m on the lottery. in my dreams

    Where you will get the answers if off CA coast, the only areas that are not a part of the monument as I understand are the private and state beaches, do not know about out in water though.

     The California Coastal National Monument runs the entire length of the California coast (840-miles) between Oregon and Mexico. Located off the 1,100 miles of California coastline, it comprises more than 20,000 small islands, rocks, exposed reefs, and pinnacles. The monument includes public lands that are exposed above mean high tide, within the corridor extending 12 nautical miles from the shoreline between Mexico and Oregon.
