What lies at the bottom of the Hudson River?

Underneath the surface of the Hudson River Estuary exists a wide range of river-bottom habitats-from the shallow, muddy bottom in the Tappan Zee and other shallow near-shore areas, to the deep, sandy bottom in the navigation channel that runs north to Albany.

Predators like blue crabs and sturgeons do eat zebra mussels, but have never been shown to control natural populations. Research on new control measures, including biological controls, is ongoing, but the changes we've seen to the Hudson's ecosystem probably are irreversible or at least long-lasting.

This results in a total of 59 bodies floating down the lower Hudson every year (49 or 50 from NYC, 5 or 6 from Bergen County, and about 4 from Hudson County). 59 divided by 365 gives you about 0.16 bodies per day.

Because the Hudson River is a tidal estuary, meaning it ebbs and flows with the ocean tide, it supports a biologically rich environment, making it an important ecosystem for various species of aquatic life. For many key species, it provides critical habitats and essential spawning and nursery grounds.

Geology. The Hudson is sometimes called, in geological terms, a drowned river. The rising sea levels after the retreat of the Wisconsin glaciation, the most recent ice age, have resulted in a marine incursion that drowned the coastal plain and brought salt water well above the mouth of the river.

While there are orange individuals in the Hudson, these tend to be easy pickings for predators; one study of the diet of ospreys along the Hudson found that goldfish were a common prey of this fish-eating hawk. Thus the goldfish we catch are more likely to be olive green or brown than orange or gold.

The Congo is the deepest river in the world. Its headwaters are in the north-east of Zambia, between Lake Tanganyika and Lake Nyasa (Malawi), 1760 metres above sea level; it flows into the Atlantic Ocean.

The short answer is “Yes!” The long answer is that it depends on when and where. Issues like sewage outflow and algal blooms keep many areas along the Hudson from being swimmable, particularly after rainfall.
