A leading bay nursery for blue crabs, the Elizabeth is also one of the busiest military and commercial ports in the world. The 250-square-mile “watershed,” or land area draining to the river, has been developed longer and more densely than most of the bay, with 400 years of filling, deepening and paving to accommodate not only the port but the old port cities of Norfolk and Portsmouth and newer suburbs in Chesapeake and Virginia Beach, VA. This report evaluates each branch, as well as three of the river’s larger creeks, to provide both a short-term, five-year snapshot of river health and also identify long-term trends. The letter grades are for the last five years. Where changes in 10-year trends can be identified, these are indicated separately and reflect 2010–2019.
