By this action, a portion of the Charles's flow was diverted, providing enough current for several mills. Unlike fresh water, which rides up and over the saline layer, the sediment falls out of the surface layer into the denser, saltier layer of water moving into the estuary. The layers of sediment with different levels of contaminants can show the past uses of the river and watershed. The saltwater is threatening drinking water supplies in the New Orleans metro area. While the problems of American estuaries are complicated and expensive, they pale in comparison to Asian estuaries. I fished the Cambridge side of lower basin today, didn't get a bite.
