Dredging, Blasting, and Scraping

Offices of JB Marine, now on dry land: from NYT
News of drought-related navigation and the efforts of the CoE to keep the river open remain in the news. An article here from the New York Times. It has taken a massive engineering effort of dredging the navigation channel, blasting known rock outcropping, and scraping along both, to keep the river at the 9' navigation depth we discussed on our tour yesterday. This rule--that the CoE must maintain a 9' channel--is the single most important legal directive that has given the agency a green-light to conduct almost any sort of ravaging to the rivers bottom. This article reads well with the previous NYT article we read for our first class. It is, to put it glibly, a "game of inches", that, despite this immediate spate of optimism, will continue to be part of the river discourse for years to come.
