at least with it piled up behind the dam you could theoretically say its contained. Of course you could always end up with it down stream and out of control like Brazil recently faced when a dam for a mining company broke. With the right equipment you could just suck up the sediment and then isolate it further. Having watched more than one youtube video of river restoration where they blow the dam from below that amount of gunk flying down stream can never be good
