A river is a natural waterway that conveys water derived from precipitation from higher ground to lower levels. Most commonly, rivers flow on the surface of the land, but there are also many examples of underground rivers, where the flow is contained within chambers, caves , or caverns. In some areas where the rainfall is highly variable, the rivers may carry water only occasionally, remaining dry for years at a time. Rivers sculpt the continents.
With the jutting jaw of a mob kingpin and the pinstripes of a Wall Street executive, striped bass swim through the brackish waters of New York Harbor like old-school New Yorkers — as if they own the place. Stripers were rare in the s, when I learned to fish along the Brooklyn waterfront. Try as I might, I never could catch one, but their magnificent ghosts were celebrated in the tales of old-salt fishermen at the bait and tackle shops I frequented. Happily, Morone saxatilis has been the beneficiary of managed catch limits, cleaner waterways and simple good fortune. It has become the poster child of successful fisheries management.

T he oysters in the Hudson River around the Statue of Liberty are some of the plumpest and fastest growing Crassostrea virginica in the whole of New York harbor. More than a quarter of an inch of rain and as much as 66m gallons of untreated waste water from all over Brooklyn flushes into the river every 24 hours. And not just organic material, which settles on the bottom. Yet the water is safe to swim by Environmental Protection Agency standards.
