If there's nothing in the water that will keep it stirred up,(i.e. bullheads, etc.) and there is vegetation on the banks to help corral the run-off, then I believe it would be a good candidate for flocculation. Check some of the other posts on muddy water to see how the other guys with the same problem took care of it.

As for the leakage, I'm sure that one of the experts will be chiming in shortly. I'm outta ideas!
