A subterranean river (also known as an underground river ) is a river or watercourse that runs wholly or partly beneath the ground , one where the riverbed does not represent the surface of the Earth. It is distinct from an aquifer , which may flow like a river but is contained within a permeable layer of rock or other unconsolidated materials. A river flowing below ground level in an open gorge is not classed as subterranean.
87-665: Kissena Creek (also Mill Creek or Ireland Mill Creek) is a buried stream located in the neighborhoods of Flushing , Fresh Meadows , Hillcrest , and Kew Gardens Hills in the New York City borough of Queens . Kissena Creek originates in a now-filled swamp within Kew Gardens Hills and Pomonok in central Queens, flowing east to Hillcrest. The creek then travels mostly north and west, largely flowing beneath Kissena Park Golf Course, Kissena Park , Kissena Corridor Park, and Queens Botanical Garden , before merging with
174-426: A "bathtub lake" with a concrete shoreline. Prior to the renovation, Kissena Lake was part of a wetland, which was believed to be a worthless type of land during the 20th century. Lacking natural aeration and warmed by its shallower depth and concrete shoreline, the lake suffered a buildup of algae. This necessitated another restoration project, which was undertaken in 1983. In 2003, a $ 2.3 million restoration drained
261-465: A fossil fuel related to coal that forms from decayed plant matter. As Kew Gardens Hills gradually developed, the swamp shrunk in size with the street grid resting on top of it. The swamp was completely drained by 1918, except for a small section under a barn, whose owner had bought the barn from the city government and moved it to the swamp's "easement area". The last remaining section of the swamp, covering 23 acres (9.3 ha), remained undeveloped through

Reversing this process is known as "daylighting" a watercourse and is a major form of visible river restoration. Successful examples include
6525-567: The surrounding neighborhoods. By 1960, about 550,000 cubic yards (420,000 m) of dirt were deposited on the park from the Long Island Expressway. Additionally, in 1959, New York City parks commissioner Robert Moses had announced that more fill would come from the Clearview Expressway , which would raise the grade of the park and end garbage landfilling. The sewers from Kissena Corridor Park flow west through
6612-500: The tides. The Mahican name of the river represents its partially estuarine nature: muh-he-kun-ne-tuk means "the river that flows both ways." Due to tidal influence from the ocean extending to Troy, NY, freshwater discharge is only about 17,400 cubic feet (490 m ) per second on average. The mean fresh water discharge at the river's mouth in New York is approximately 21,900 cubic feet (620 m ) per second. The Hudson River
6699-413: The vicinity of present-day Albany, reaching an end to navigation. The Dutch subsequently began to colonize the region, establishing the colony of New Netherland , including three major fur-trading outposts: New Amsterdam , Wiltwyck , and Fort Orange . New Amsterdam was founded at the mouth of the Hudson River, and would later become known as New York City . Wiltwyck was founded roughly halfway up
6786-646: The village of Peekskill and capturing the two forts. In 1778, the Continentals constructed the Great West Point Chain in order to prevent another British fleet from sailing up the Hudson. Hudson River School paintings reflect the themes of discovery, exploration, and settlement in America in the mid-19th century. The detailed and idealized paintings also typically depict a pastoral setting. The works often juxtapose peaceful agriculture and
6873-585: The water empties into the Flushing River (also known as Flushing Creek). The Flushing River flows north into Flushing Bay , part of the East River , which in turn is an arm of the Atlantic Ocean . Formerly, Kissena Creek flowed from the Botanical Garden site directly into Flushing Meadows , merging with the Flushing River near the site of the present-day Fountain of the Planets. Prior to
6960-467: The west end of Kissena Corridor Park adjacent to the World's Fair Grounds. This site was originally planned to be used as parking space for the fair. Instead, the Queens Botanical Garden was built, and it was dedicated on October 19, 1963. The QBG's 2001 Master Plan included the construction of a self-sustaining ecosystem. The plan consisted of a stream forming from rainwater collected atop the roof of its administration building, flowing through pools towards
7047-402: Was adapted from the path of Kissena Creek, which had been gradually diverted into the sewer during the mid-20th century. In 1934, the creek was placed in a culvert at its crossing with Main Street (then called Jagger Avenue), as part of a widening project for the street. The Kissena Corridor project was initiated in the 1930s as a greenbelt to link several parks in eastern Queens. It included
7134-456: Was also the eastern outlet for the Erie Canal , which, when completed in 1825, became an important transportation artery for the early 19th century United States. Pollution in the Hudson River increased in the 20th century, more acutely by mid-century, particularly with industrial contamination from polychlorinated biphenyls , also known by their acronym PCBs. Pollution control regulations, enforcement actions and restoration projects initiated in
7221-516: Was an ineffable manifestation of God, though the artists varied in the depth of their religious conviction. Their reverence for America's natural beauty was shared with contemporary American writers such as Henry David Thoreau and Ralph Waldo Emerson . The artist Thomas Cole is generally acknowledged as the founder of the Hudson River School , his work first being reviewed in 1825, while painters Frederic Edwin Church and Albert Bierstadt were
7308-435: Was connecting Staten Island and Brooklyn to form the Narrows as it exists today. This allowed the Hudson River to find a shorter route to the Atlantic Ocean via its present course between New Jersey and New York City. Suspended sediments, mainly consisting of clays eroded from glacial deposits and organic particles, can be found in abundance in the river. The Hudson has a relatively short history of erosion, so it does not have
7395-429: Was formerly a swamp in the modern Kew Gardens Hills and Pomonok areas. The swamp was variously known as "Peat Bog Swamp", "Old Crow Swamp", "Doughty's Swamp", and "Gutman's Swamp". The 140-acre (57 ha) swamp was bound by Vleigh Place near Main Street to its west, and Kissena Boulevard and Parsons Boulevard to the east. When Parsons and Kissena Boulevards were laid out as the combined "Jamaica and Flushing Road",
7482-1040: Was the Rio San Antonio as named by the Portuguese explorer in Spain's employ, Estêvão Gomes , who explored the Mid-Atlantic coast in 1525. Another early name for the Hudson used by the Dutch was Rio de Montaigne . Later, they generally termed it the Noortrivier , or " North River ", the Delaware River being known as the Zuidrivier , or "South River". Other occasional names for the Hudson included Manhattes rieviere "Manhattan River", Groote Rivier "Great River", and de grootte Mouritse reviere , or "the Great Maurits River" (after Maurice, Prince of Orange ). The translated name North River
7569-583: Was used in the New York metropolitan area up until the early 1900s, with limited use continuing into the present day. The term persists in radio communication among commercial shipping traffic, especially below the Tappan Zee . The term also continues to be used in names of facilities in the river's southern portion, such as the North River piers , North River Tunnels , and the North River Wastewater Treatment Plant . It
