The '''Delaware River''' is a major [[river]] in the [[Mid-Atlantic (United States)|Mid-Atlantic]] region of the United States. From the meeting of its branches in [[Hancock (village), New York|Hancock, New York]], the river flows for {{convert|282|mi}}<ref name="river-mileage">{{cite web|title=DRB river-mileage spreadsheet |url=https://www.state.nj.us/drbc/library/documents/DRB_river-mileage-spreadsheet.pdf |website=River Mileage System |publisher=Delaware River Basin Commission |access-date=24 October 2022}}</ref> along the borders of [[New York (state)|New York]], [[Pennsylvania]], [[New Jersey]], and [[Delaware]], before emptying into [[Delaware Bay]]. It is the longest free-flowing river in the [[Eastern United States]].


The river has been recognized by the [[National Wildlife Federation]] as one of the country's Great Waters<ref>{{cite news|author=National Wildlife Federation|title=America's Great Waters Coalition|date=August 18, 2010|url=http://www.nwf.org/Wildlife/What-We-Do/Waters/Great-Waters-Restoration/Great-Waters-Coalition.aspx|access-date=August 18, 2011|archive-url=https://web.archive.org/web/20110815213851/http://www.nwf.org/Wildlife/What-We-Do/Waters/Great-Waters-Restoration/Great-Waters-Coalition.aspx|archive-date=August 15, 2011|url-status=live}}</ref> and has been called the "Lifeblood of the Northeast."<ref>{{cite web |title=Delaware River |url=https://www.americanrivers.org/river/delaware-river/ |website=www.americanrivers.org |publisher=American Rivers |access-date=23 March 2023}}</ref> Its [[drainage basin|watershed]] drains an area of {{convert|13539|sqmi}} and provides drinking water for 17&nbsp;million people, including half of [[New York City]] via the [[Delaware Aqueduct]].

The Delaware River has two branches that rise in the [[Catskill Mountains]] of New York: the [[West Branch Delaware River|West Branch]] at [[Mount Jefferson (New York)|Mount Jefferson]] in [[Jefferson, New York|Jefferson]], [[Schoharie County, New York|Schoharie County]], and the [[East Branch Delaware River|East Branch]] at [[Grand Gorge, New York|Grand Gorge]], [[Delaware County, New York|Delaware County]]. The branches merge to form the main Delaware River at [[Hancock (village), New York|Hancock, New York]]. Flowing south, the river remains relatively undeveloped, with {{convert|152|mi}} protected as the [[Upper Delaware Scenic and Recreational River|Upper]], [[Middle Delaware National Scenic River|Middle]], and [[Lower Delaware National Wild and Scenic River|Lower]] Delaware [[National Wild and Scenic Rivers System|National Scenic Rivers]].<ref>{{cite web|title=National Wild and Scenic Rivers in the DRB |url=https://nj.gov/drbc/basin/wild.html |website=nj.gov |publisher=Delaware River Basin Commission |access-date=24 October 2022}}</ref> At [[Trenton, New Jersey]], the Delaware becomes [[tidal river|tidal]], [[navigability|navigable]], and significantly more [[maritime industry|industrial]].

Before the arrival of European settlers, the river was the homeland of the [[Lenape]] Native Americans. They called the river Lenapewihittuk, or Lenape River, and Kithanne, meaning the largest river in this part of the country.<ref>{{citation |last1=Heckewelder |first1=John |last2=Du Ponceau |first2=Peter S. |date=1834 |title=Names which the Lenni Lenape or Delaware Indians, who once inhabited this country, had given to Rivers, Streams, Places, &c. |jstor=1004837 |journal=Transactions of the American Philosophical Society |volume=4 |pages=351–396|doi=10.2307/1004837 }}</ref>

In 1609, the river was visited by a [[Dutch East India Company]] expedition led by [[Henry Hudson]]. Hudson, an English navigator, was hired to find a western route to [[Cathay]] (China), but his discoveries set the stage for [[New Netherland|Dutch colonization of North America]] in the 17th century. Early Dutch and Swedish settlements were established along the lower section of the river and [[Delaware Bay]]. Both [[colonialism|colonial powers]] called the river the ''South River'' (Zuidrivier), compared to the [[Hudson River]], which was known as the ''North River''. After the English expelled the Dutch and took control of the New Netherland colony in 1664, the river was renamed ''Delaware'' after [[Thomas West, 3rd Baron De La Warr|Sir Thomas West]], 3rd Baron De La Warr, an English nobleman and the Virginia colony's first royal governor who defended the colony during the [[First Anglo-Powhatan War]].

It has often been reported that the river and bay received the name "Delaware" after [[English colonial empire|English]] forces under [[Richard Nicolls]] expelled the [[Dutch colonization of the Americas|Dutch]] and took control of the [[New Netherland|New Netherland colony]] in 1664.<ref>World Digital Library.

===West Branch of the Delaware===
{{main|West Branch Delaware River}}
The [[West Branch Delaware River|West Branch of the Delaware River]], also called the Mohawk Branch, spans approximately {{convert|90|mi|km}} from the northern [[Catskill Mountains]] to its [[confluence]] with the Delaware River's East Branch at [[Hancock, New York]]. The last {{convert|6|mi|km}} forms part of [[New York–Pennsylvania border|the boundary between New York and Pennsylvania]].
 
The West Branch rises in [[Schoharie County, New York|Schoharie County]], New York at {{convert|1886|ft}} above sea level, near [[Mount Jefferson (New York)|Mount Jefferson]], and flows tortuously through the plateau in a deep trough. The branch flows generally southwest, entering [[Delaware County, New York|Delaware County]] and flowing through the towns of [[Stamford, New York|Stamford]] and [[Delhi, New York|Delhi]]. In southwestern Delaware County it flows in an increasingly winding course through the mountains, generally southwest. At [[Stilesville, New York|Stilesville]] the West Branch was impounded in the 1960s to form the [[Cannonsville Reservoir]], the westernmost of the reservoirs in the New York City water system. It is the most recently constructed New York City reservoir and began serving the city in 1964. Draining a large watershed of {{convert|455|sqmi}}, the reservoir's capacity is {{convert|95.7|e9USgal|m3}}. This water flows over halfway through the reservoir to enter the {{convert|44|mi|km|adj=on}} West Delaware Tunnel in [[Tompkins, New York|Tompkins]], New York. Then it flows through the aqueduct into the [[Rondout Reservoir]], where the water enters the {{convert|85|mi|km}} [[Delaware Aqueduct]], that contributes to roughly 50% of the city's drinking water supply. At [[Deposit (town), New York|Deposit]], on the border between [[Broome County, New York|Broome]] and Delaware counties, it turns sharply to the southeast and is paralleled by [[New York State Route&nbsp;17]]. It joins the East Branch at {{convert|880|ft}} above sea level at [[Hancock (town), New York|Hancock]] to form the Delaware.
 
===East Branch of the Delaware===
{{main|East Branch Delaware River}}
Similarly, the [[East Branch Delaware River|East Branch]] begins from a small pond south of [[Grand Gorge, New York|Grand Gorge]] in the [[List of towns in New York (state)|town]] of [[Roxbury, New York|Roxbury]] in [[Delaware County, New York|Delaware County]], flowing southwest toward its impoundment by New York City to create the [[Pepacton Reservoir]], the largest reservoir in the [[New York City water supply system]]. Its tributaries are the Beaver Kill River and the Willowemoc Creek which enter into the river {{convert|10|mi|km|spell=in}} before the West Branch meets the East Branch. The confluence of the two branches is just south of [[Hancock (village), New York|Hancock]].
 
The East Branch and West Branch of the Delaware River parallel each other, both flowing in a southwesterly direction.
 
===Upper Delaware Valley===
From [[Hancock, New York]], the Delaware flows between the northern [[Pocono Mountains|Poconos]] in Pennsylvania, and the lowered shale beds north of the Catskills. The river flows down a broad [[Appalachian Mountains|Appalachian]] valley, passing [[Hawk's Nest, New York|Hawk's Nest overlook]] on the Upper Delaware Scenic Byway. The river flows southeast for 78 miles through rural regions along the New York-Pennsylvania border to Port Jervis and  [[Shawangunk Ridge]].<!--{{rp|p.9}}

===The Minisink===
{{Main|Minisink}}
At [[Port Jervis, New York|Port Jervis]], New York, it enters the Port Jervis trough. At this point, the Walpack Ridge deflects the Delaware into the Minisink Valley, where it follows the southwest [[Strike and dip|strike]] of the eroded [[Marcellus Formation]] [[bed (geology)|beds]] along the Pennsylvania–New Jersey state line for {{convert|25|mi|km}} to the end of the ridge at Walpack Bend in the [[Delaware Water Gap National Recreation Area]].<ref name="White">{{cite web|url=http://www.njgeology.org/enviroed/newsletter/v2n1.pdf |title=Karst in the Delaware Water Gap National Recreation Area |author1=White, Ron W. |author2=Monteverde, Donald H. |work=Unearthing New Jersey Vol. 2, No. 1 |date=Feb 2006 |access-date=June 7, 2008 |publisher=New Jersey Geological Survey |archive-url=https://web.archive.org/web/20080910033019/http://www.njgeology.org/enviroed/newsletter/v2n1.pdf |archive-date=September 10, 2008 |url-status=live}}</ref><ref name="White1882">{{cite book| author = White, I.C. |author2=Chance, H.M. | year = 1882 | title = The geology of Pike and Monroe counties | series = Second Geol.

The Minisink is a [[buried valley]] where the Delaware flows in a bed of [[glacier|glacial]] [[till]] that buried the eroded bedrock during the [[last glacial period]]. It then skirts the [[Kittatinny Mountains|Kittatinny ridge]], which it crosses at the [[Delaware Water Gap]], between nearly vertical walls of [[sandstone]], [[quartzite]], and [[conglomerate (geology)|conglomerate]], and then passes through a quiet and charming country of farm and forest, diversified with plateaus and escarpments, until it crosses the Appalachian plain and enters the hills again at [[Easton, Pennsylvania|Easton]], Pennsylvania. From this point it is flanked at intervals by fine hills, and in places by cliffs, of which the finest are the Nockamixon Cliffs, {{convert|3|mi|0}} long and above {{convert|200|ft}} high.
 
The [[Appalachian Trail]], which traverses the ridge of Kittatinny Mountain in New Jersey, and Blue Mountain in Pennsylvania, crosses the Delaware River at the Delaware Water Gap near Columbia, New Jersey.
 
===Central Delaware Valley===
In [[Easton, Pennsylvania]], the [[Lehigh River]] joins the Delaware. At [[Trenton, New Jersey|Trenton]], the Delaware crosses the [[Atlantic Seaboard Fall Line]] with a drop of {{convert|8|ft}}.
 
===Lower Delaware and Tidewater===
{{See also|Delaware Valley}}
Below [[Trenton, New Jersey|Trenton]], the Delaware flows between [[Philadelphia]] and [[New Jersey]] before becoming a broad, sluggish inlet of the sea, with many marshes along its side, widening steadily into its great estuary, [[Delaware Bay]].
 
The Delaware River constitutes the boundary between Delaware and New Jersey. The Delaware-New Jersey border is actually at the easternmost river shoreline within the [[Twelve-Mile Circle|Twelve-Mile Circle of New Castle]], rather than at mid-river, mid-channel or [[thalweg]], so small portions of land lying west of the shoreline, but on the New Jersey side of the river, are [[pene-exclave]]s under the jurisdiction of Delaware. The rest of the borders follow a mid-channel approach.
 
==History==
At the time of the arrival of the [[Europe]]ans in the early 17th century, the area near the Delaware River was inhabited by the Native American [[Lenape]] people. They called the Delaware River "Lenape Wihittuck", which means "the rapid stream of the Lenape".<ref name ="USGSDel">[http://pubs.usgs.gov/bul/1245/report.pdf Delaware Place Names] {{Webarchive|url=https://web.archive.org/web/20170811214125/https://pubs.usgs.gov/bul/1245/report.pdf |date=August 11, 2017 }} [[United States Geological Survey]]</ref> The Delaware River played a key factor in the economic and social development of the Mid-Atlantic region. In the seventeenth century it provided the conduit for colonial settlement by the [[Dutch Empire|Dutch]] ([[New Netherland]]), the [[Swedish colonial empire|Swedish]] ([[New Sweden]]). Beginning in 1664, the region became an [[English colonial empire|English possession]] as settlement by Quakers established the colonies of [[Province of Pennsylvania|Pennsylvania]] (including present-day [[Delaware]]) and [[Province of West Jersey|West Jersey]]. In the eighteenth century, cities like [[Philadelphia]], [[Camden, New Jersey|Camden]] (then Cooper's Ferry), [[Trenton, New Jersey|Trenton]] and [[Wilmington, Delaware|Wilmington]], and [[New Castle, Delaware|New Castle]] were established upon the Delaware and their continued commercial success into the present day has been dependent on access to the river for trade and power. The river provided the path for the settlement of northeastern Pennsylvania's [[Lehigh Valley]], and northwestern New Jersey by [[German Palatine]] immigrants—a population that became key in the agricultural development of the region.
 
===American Revolutionary War===
{{see also|American Revolutionary War}}
The strategic Delaware River was the scene of several important campaigns during the [[American Revolutionary War]]. Perhaps the most famous event was [[George Washington's crossing of the Delaware River]] with the [[Continental Army]] on the night of December&nbsp;25–26, 1776, leading to a successful [[Battle of Trenton|surprise attack and victory]] against the [[Hessian (soldiers)|Hessian troops]] occupying [[Trenton, New Jersey]], on the morning of December 26.<ref>[[#savas2006|Savas, 2006]], p. 84</ref><ref>[[#brooks1999|Brooks, 1999]] p. 55</ref>
 
During the [[Philadelphia Campaign]] control of the Delaware River was urgently needed by the British, allowing their naval fleet to supply troops occupying Philadelphia. To this end, the [[Battle of Red Bank]] and the [[Siege of Fort Mifflin]] were fought on and along the shores of the Delaware by the American and British navies, commanded by [[John Hazelwood|Commodore John Hazelwood]] and [[Francis Reynolds-Moreton, 3rd Baron Ducie|Admiral Francis Reynolds]] respectively.<ref>[[#dorwart1998|Dorwart 1998]], pp. 40–41</ref><ref>[[#leach02|Leach, 1902]], p. 2</ref><ref>[[#mcgeorge1905|McGeorge, 1905]], pp. 3–7</ref> See [[:File:Philadelphia Map, 1777 Philadelphia Campaign2.jpg|historical map]] of that campaign.
 
===Canals===
The magnitude of the commerce of [[Philadelphia]] has made the improvements of the river below that port of great importance. Small improvements were attempted by [[Pennsylvania]] as early as 1771. Commerce was once important on the upper river, primarily prior to railway competition of 1857.
 
* The [[Pennsylvania Canal (Delaware Division)|Delaware Division of the Pennsylvania Canal]], running parallel with the river from Easton to Bristol, opened in 1830.
* The [[Delaware and Raritan Canal]], which runs along the New Jersey side of the Delaware River from Bulls Island, New Jersey to [[Trenton, New Jersey|Trenton]], unites the waters of the Delaware and [[Raritan River|Raritan rivers]] as it empties the waters of the Delaware River via the canal outlet in [[New Brunswick, New Jersey|New Brunswick]]. This canal water conduit is still used as a water supply source by the State of [[New Jersey]].
* The [[Morris Canal]] (now abandoned and almost completely filled in) and the [[Delaware and Hudson Canal]] connected the Delaware and [[Hudson River|Hudson rivers]].
* The [[Chesapeake and Delaware Canal]] joins the waters of the Delaware with those of the [[Chesapeake Bay]].
 
===Delaware Water Gap National Recreation Area===
{{See also|Tocks Island Dam Controversy}}
The [[Delaware Water Gap National Recreation Area]] came about as a result of the failure of a controversial plan to build a dam on the Delaware River at [[Tocks Island]], just north of the [[Delaware Water Gap]] to control water levels for flood control and hydroelectric power generation. The dam would have created a {{convert|37|mi|km|adj=on}} lake in the center of present park for use as a reservoir. Starting in 1960, the present-day area of the Recreation Area was acquired for the [[United States Army Corps of Engineers|Army Corps of Engineers]] through [[eminent domain]]. Between 3,000 and 5,000 dwellings were demolished, including historical sites, and about 15,000 people were displaced by the project.
 
Because of massive environmental opposition, dwindling funds, and an unacceptable geological assessment of the dam's safety, the government transferred the property to the [[National Park Service]] in 1978. The National Park Service found itself as the caretaker of the previously endangered territory, and with the help of the federal government and surrounding communities, developed recreational facilities and worked to preserve the remaining historical structures.<ref>''Delaware Water Gap National Recreation Area'' (pp. 7–8), Obiso, Laura, 2008.</ref><ref>[http://www.njskylands.com/pkdwgnra.htm Delaware Water Gap National Recreation Area] {{Webarchive|url=https://web.archive.org/web/20110803140204/http://www.njskylands.com/pkdwgnra.htm |date=August 3, 2011 }}, ''njskylands.com''.</ref>

===Wine regions===
{{See also|New Jersey wine|Pennsylvania wine}}
In 1984, the [[U.S. Department of the Treasury]] authorized the creation of a wine region or "[[American Viticultural Area]]" called the [[Central Delaware Valley AVA]] located in southeastern [[Pennsylvania]] and [[New Jersey]].

==Environmental issues==
===New York City water supply===
{{further|New York City water supply system}}
After [[New York City]] built 15 reservoirs to supply water to the city's growing population, it was unable to obtain permission to build an additional five reservoirs along the Delaware River's tributaries. As a result, in 1928 the city decided to draw water from the Delaware River, putting them in direct conflict with villages and towns across the river in [[Pennsylvania]] which were already using the Delaware for their water supply. The two sides eventually took their case to the [[U.S. Supreme Court]], and in 1931, New York City was allowed to draw {{convert|440|e6USgal|m3}} of water a day from the Delaware and its upstream tributaries.

In 2015, the [[United States Environmental Protection Agency|EPA]] saw the Delaware River as a concern for mass pollution especially in the Greater Philadelphia and Chester, Pennsylvania area. The EPA was involved after accusations that the river met standards made illegal by the [[Clean Water Act]]. In complying with the Clean Water Act, the EPA involved the Delaware County Regional Water Authority (DELCORA) where they set up a plan to spend around $200&nbsp;million to help rid the waterway of about 740&nbsp;million gallons of sewage and pollution. DELCORA was also fined about $1.4&nbsp;million for allowing the Delaware River to have so much pollution residing in the river in the first place and for not complying with the Clean Water Act.<ref>{{cite web|title=Settlement to Improve Water Quality in Delaware River, Philadelphia-Area Creeks|work=U.S. EPA Region 3 Water Protection Division|date=August 20, 2015|url=https://www.epa.gov/pa/settlement-improve-water-quality-delaware-river-philadelphia-area-creeks|access-date=January 28, 2020|archive-url=https://web.archive.org/web/20200128180617/https://www.epa.gov/pa/settlement-improve-water-quality-delaware-river-philadelphia-area-creeks|archive-date=January 28, 2020|url-status=live}}</ref>
 
Part of the Clean Water Act explains how conditions of the river should be stable enough for human fishing and swimming.{{Citation needed|date=March 2023}}  Even though the river has had success with the cleanup of pollution, the Delaware River still does not meet that standard of swimmable or fishable conditions in the Philadelphia/Chester region.

===Flooding===
With the failure of the dam project to come to fruition, the lack of flood control on the river left it vulnerable, and it has experienced a number of serious flooding events as the result of snow melt or rain run-off from heavy rainstorms. Record flooding occurred in August 1955, in the aftermath of the passing of the remnants of two separate hurricanes over the area within less than a week: first [[Hurricane Connie]] and then [[Hurricane Diane]], which was, and still is, the wettest tropical cyclone to have hit the northeastern United States. The river gauge at [[Riegelsville, Pennsylvania|Riegelsville]], Pennsylvania recorded an all-time record crest of {{convert|38.85|ft}} on August 19, 1955.
 
More recently, moderate to severe flooding has occurred along the river. The same gauge at Riegelsville recorded a peak of {{convert|30.95|ft}} on September 23, 2004, {{convert|34.07|ft}} on April 4, 2005, and {{convert|33.62|ft}} on June 28, 2006, all considerably higher than the flood stage of {{convert|22|ft}}.<ref>[http://nj.usgs.gov/special/flood0606/ USGS] {{webarchive|url=https://web.archive.org/web/20070213212133/http://nj.usgs.gov/special/flood0606/|date=February 13, 2007}}

Since the upper Delaware basin has few population centers along its banks, flooding in this area mainly affects natural unpopulated flood plains. Residents in the middle part of the Delaware basin experience flooding, including three major floods in the three years (2004–2006) that have severely damaged their homes and land. The lower part of the Delaware basin from Philadelphia southward to the Delaware Bay is tidal and much wider than portions further north, and is not prone to river-related flooding (although tidal surges can cause minor flooding in this area).
 
The [[Delaware River Basin Commission]], along with local governments, is working to try to address the issue of flooding along the river. As the past few years have seen a rise in catastrophic floods, most residents of the river basin feel that something must be done. The local governments have worked in association with FEMA to address many of these problems, however, due to insufficient federal funds, progress is slow.<ref>Delaware River Basin Commission (July 20, 2005).
