The upper portion (from Long Island Sound to Hell Gate), running largely perpendicular to the glacial motion, is wide, meandering, and has deep narrow bays on both banks, scoured out by the glacier's movement. The lower portion (from Hell Gate to New York Bay) runs north–south, parallel to the glacial motion. It is much narrower, with straight banks. The bays that exist, as well as those that used to exist before being filled in by human activity, are largely wide and shallow. PSM V28 D451 Hell gate new york

Narrowing the river

Historically, the lower portion of the strait, which separates Manhattan from Brooklyn, was one of the busiest and most important channels in the world, particularly during the first three centuries of New York City's history. Because the water along the lower Manhattan shoreline was too shallow for large boats to tie up and unload their goods, from 1686 on – after the signing of the Dongan Charter, which allowed intertidal land to be owned and sold – the shoreline was "wharfed out" to the high-water mark by constructing retaining walls that were filled in with every conceivable kind of landfill: excrement, dead animals, ships deliberately sunk in place, ship ballast, and muck dredged from the bottom of the river. On the new land were built warehouses and other structures necessary for the burgeoning sea trade. Many of the "water-lot" grants went to the rich and powerful families of the merchant class, although some went to tradesmen. By 1700, the Manhattan bank of the river had been "wharfed-out" up to around

These prisoners had come into the hands of the British after the fall of New York City on September 15, 1776, after the American loss at the Battle of Long Island and the loss of Fort Washington on November 16. Prisoners began to be housed on the broken-down warships and transports in December; about 24 ships were used in total, but generally only 5 or 6 at a time. Almost twice as many Americans died from neglect in these ships than did from all the battles in the war: as many as 12,000 soldiers, sailors and civilians. The bodies were thrown overboard or were buried in shallow graves on the riverbanks, but their bones – some of which were collected when they washed ashore – were later relocated and are now inside the

Development begins again

After the war, East River waterfront development continued once more. New York State legislation, which in 1807 had authorized what would become the Commissioners Plan of 1811, authorized the creation of new land out to 400 feet from the low water mark into the river, and with the advent of gridded streets along the new waterline – Joseph Mangin had laid out such a grid in 1803 in his ''A Plan and Regulation of the City of New York'', which was rejected by the city, but established the concept – the coastline become regularized at the same time that the strait became even narrower. One result of the narrowing of the East River along the shoreline of Manhattan and, later, Brooklyn – which continued until the mid-19th century when the state put a stop to it – was an increase in the speed of its current.

from Red Hook in Brooklyn, and which is located directly south of the "mouth" of the East River, was in the early 17th century a fordable waterway across which cattle could be driven. Further investigation by Colonel Jonathan Williams determined that the channel was by 1776 three fathoms deep (), five fathoms deep () in the same spot by 1798, and when surveyed by Williams in 1807 had deepened to 7 fathoms () at low tide. What had been almost a bridge between two landforms that were once connected had become a fully navigable channel, thanks to the constriction of the East River and the increased flow it caused. Soon, the current in the East River had become so strong that larger ships had to use auxiliary steam power in order to turn. The continued narrowing of the channel on both side may have been the reasoning behind the suggestion of one New York State Senator, who wanted to fill in the East River and annex Brooklyn, with the cost of doing so being covered by selling the newly made land. Others proposed a dam at Roosevelt Island (then Blackwell's Island) to create a wet basin for shipping.Steinberg, p.127 New York and Vicinity as Proposed to be Remodeled crop

Filling in the river

Filling in part of the river was also proposed in 1867 by engineer James E. Serrell, later a city surveyor, but with emphasis on solving the problem of Hell Gate. Serrell proposed filling in Hell Gate and building a "New East River" through Queens with an extension to

. Serrell's plan – which he publicized with maps, essay and lectures as well as presentations to the city, state and federal governments – would have filled in the river from 14th Street to 125th Street. The New East River through Queens would be about three times the average width of the existing one at an even throughout, and would run as straight as an arrow for . The new land, and the portions of Queens which would become part of Manhattan, adding , would be covered with an extension of the existing street grid of Manhattan. Variations on Serrell's plan would be floated over the years. A pseudonymous "Terra Firma" brought up filling in the East River again in the ''Evening Post'' and ''

took it up in 1906. Then Thomas Kennard Thompson, a bridge and railway engineer, proposed in 1913 to fill in the river from Hell Gate to the tip of Manhattan and, as Serrell had suggested, make a new canalized East River, only this time from

to Jamaica Bay. He would also expand Brooklyn into the Upper Harbor, put up a dam from Brooklyn to Staten Island, and make extensive landfill in the Lower Bay. At around the same time, in the 1920s, Dr. John A. Harriss, New York City's chief traffic engineer, who had developed the first traffic signals in the city, also had plans for the river. Harriss wanted to dam the East River at Hell Gate and the Williamsburg Bridge, then remove the water, put a roof over it on stilts, and build boulevards and pedestrian lanes on the roof along with "majestic structures", with transportation services below. The East River's course would, once again, be shifted to run through Queens, and this time Brooklyn as well, to channel it to the Harbor.

Clearing Hell Gate

Periodically, merchants and other interested parties would try to get something done about the difficulty of navigating through Hell Gate. In 1832, the New York State legislature was presented with a petition for a canal to be built through nearby Hallet's Point, thus avoiding Hell Gate altogether. Instead, the legislature responded by providing ships with pilots trained to navigate the shoals for the next 15 years.Eldredge & Horenstein (2014), p.93 In 1849, a French engineer whose specialty was underwater blasting, Benjamin Maillefert, had cleared some of the rocks which, along with the mix of tides, made the Hell Gate stretch of the river so dangerous to navigate. Ebenezer Meriam had organized a subscription to pay Maillefert $6,000 to, for instance, reduce "Pot Rock" to provide of depth at low-mean water. While ships continued to run aground (in the 1850s about 2% of ships did so) and petitions continued to call for action, the federal government undertook surveys of the area which ended in 1851 with a detailed and accurate map. By then Maillefert had cleared the rock "Baldheaded Billy", and it was reported that Pot Rock had been reduced to , which encouraged the

In the 1850s the depth continued to lessen – the harbor commission said in 1850 that the mean water low was and the extreme water low was – while the draft required by the new ships continued to increase, meaning it was only safe for them to enter the harbor at high tide.Eldredge & Horenstein (2014), pp.94–95 The U.S. Congress, realizing that the problem needed to be addressed, appropriated $20,000 for the Army Corps of Engineers to continue Maillefert's work.Eldredge & Horenstein (2014), p.95 In 1851, the

The appropriated money was soon spent without appreciable change in the hazards of navigating the strait. An advisory council recommended in 1856 that the strait be cleared of all obstacles, but nothing was done, and the

soon broke out.

After the Civil War

In the late 1860s, after the Civil War, Congress realized the military importance of having easily navigable waterways, and charged the Army Corps of Engineers with clearing Hell Gate. Newton estimated that the operation would cost about half as much as the annual losses in shipping. On September 24, 1876, the Corps used of explosives to blast the rocks, which was followed by further blasting. The process was started by excavating under Hallets reef from Astoria. Cornish miners, assisted by steam drills, dug galleries under the reef, which were then interconnected. They later drilled holes for explosives. A patent was issued for the detonating device.

Ironically, though, while both forks of the northern shipping entrance to the city were now open, modern dredging techniques had cut through the sandbars of the Atlantic Ocean entrance, allowing new, even larger ships to use that traditional passage into New York's docks. At the beginning of the 19th century, the East River was the center of New York's shipping industry, but by the end of the century, much of it had moved to the Hudson River, leaving the East River wharves and slips to begin a long process of decay, until the area was finally rehabilitated in the mid-1960s, and the

A new seawall

By 1870, the condition of the Port of New York along both the East and Hudson Rivers had so deteriorated that the New York State legislature created the Department of Docks to renovate the port and keep New York competitive with other ports on the American East Coast. The Department of Docks was given the task of creating the master plan for the waterfront, and General

was engaged to head the project. McClellan held public hearings and invited plans to be submitted, ultimately receiving 70 of them, although in the end he and his successors put his own plan into effect. That plan called for the building of a seawall around Manhattan island from West 61st Street on the Hudson, around The Battery, and up to East 51st Street on the East River. The area behind the masonry wall (mostly concrete but in some parts granite blocks) would be filled in with landfill, and wide streets would be laid down on the new land. In this way, a new edge for the island (or at least the part of it used as a commercial port) would be created.Eldredge & Horenstein (2014), pp.184–186 The department had surveyed of shoreline by 1878, as well as documenting the currents and tides.

(The Hurricane of September 3, 1821, created the biggest storm surge on record in New York City: a rise of in one hour at the Battery, flooding all of lower Manhattan up to Canal Street.) Still, the new seawall begun in 1871 gave the island a firmer edge, improved the quality of the port, and continues to protect Manhattan from normal storm surges.

Ecosystem collapse, pollution and health

, the waste that was flushed away into the sewers, where it mixed with ground runoff, ran directly into the river, untreated. The sewers terminated at the slips where ships docked, until the waste began to build up, preventing dockage, after which the outfalls were moved to the end of the piers. The "landfill" which created new land along the shoreline when the river was "wharfed out" by the sale of "water lots" was largely garbage such as bones, offal, and even whole dead animals, along with excrement – human and animal. The result was that by the 1850s, if not before, the East River, like the other waterways around the city, was undergoing the process of

Also harmful was the general destruction of the once plentiful oyster beds in the waters around the city,Oysters were so plentiful in New Amsterdam and early New York that they were considered to be food for the poor, although the rich also ate them in great numbers. They were sold in specialized "oyster shops" and by vendors on the street, some of which were paved with their shells. Pearl Street was named after the piles of oysters left there by the Native Americans of the area. "Enjoy the oysters" was often said to a person planning on traveling to New York City, so strong was the bivalve as an icon of the city. It was only after the collapse of the local oyster beds, by around 1920, that oysters became scarce, and a delicacy only affordable by the rich.Burrows and Wallace, pp.460, 798, 816

The combination of more sewage, due to the availability of more potable water – New York's water consumption ''per capita'' was twice that of Europe – indoor plumbing, the destruction of filter feeders, and the collapse of the food chain, damaged the ecosystem of the waters around New York, including the East River, almost beyond repair. Because of these changes to the ecosystem, by 1909, the level of dissolved-oxygen in the lower part of the river had declined to less than 65%, where 55% of saturation is the point at which the amount of fish and the number of their species begins to be affected. Only 17 years later, by 1926, the level of dissolved oxygen in the river had fallen to 13%, below the point at which most fish species can survive. Due to heavy

In the past the Coast Guard has on average been able to recover about 10% of oil spilled, however the complex tides in the river make the recovery much more difficult, with the turbulent water caused by the river's change of tides pushing contaminated water over the containment booms, where it is then carried out to sea and cannot be recovered.

On June 22, Con Edison used non-toxic green dye and divers in the river to find the source of the leak. As a result, a hole was plugged. The utility continued to believe that the bulk of the spill went into the ground around the substation, and excavated and removed several hundred cubic yards of soil from the area. They estimated that about went into the river, of which were recovered. Con Edison said that it installed a new transformer, and intended to add new barrier around the facility to help guard against future spills propagating into the river.
