New Rochelle has likewise been converted into county-run Pocantico Lake Park. While the river runs predominantly through those parks and suburban land,[4] it is still one of the most polluted tributaries of the Hudson.[5]

Course

In the past the Pocantico was considered to have two different sources, but today it is acknowledged that it rises from Echo Lake in

hamlet of Millwood. The lake is 325 feet (99 m) above sea level, in a narrow valley between Cabin Ridge to the east and a similarly steep ridge on the west. Its surrounding terrain is primarily wooded and lightly developed outside of the two roads. The river begins at a dam on the lake's south end.[6][7]

Shortly after draining the lake, the Pocantico flows under Route 100, which it remains closely parallel to for the next few miles. About 1,200 feet (370 m) from its source, the stream crosses the town line from New Castle into neighboring

village line at the Chappaqua Road crossing.[7][8]

Another 1,200 feet south of that crossing, it recrosses Saw Mill River Road just north of where it merges with the Briarcliff–

Peekskill Parkway (also State Route 9A). After flowing under the parkway, it passes just east of downtown Briarcliff Manor and then crosses Saw Mill River Road and the parkway again, meandering a little further to the east into residential neighborhoods, then turning south through the village's Jackson Road Park. After that it flows due south to the immediate east of the parkway, itself to the immediate east of a steep slope.[9]

After a slight swing east towards the Taconic, the river crosses under the parkway for the last time and continues on a more southwesterly course past 420-foot (130 m) Beech Hill into 164-acre (66 ha) Pocantico Lakes Park. It widens amid swampy areas on either side as it receives Caney Brook from the north and then becomes Pocantico Lake. Midway along the lake, the municipal boundary leaves the river, putting it entirely within the town of Mount Pleasant. The dam at the lake's south end is at 219 feet (67 m) above sea level, a loss of 106 feet (32 m) from the Pocantico's source at Echo Lake.[10][11]

From there, it flows southwestward again. At Old Sleepy Hollow Road it enters Rockefeller State Park Preserve, at over 1,400 acres (570 ha) the largest of the three protected areas the river flows through. The road continues to parallel it on the east as it turns south; on the west it is paralleled by the preserve's Pocantico River Trail, which follows it for a mile and a half (2.4 km).[12] All three cross under Phelps Way (State Route 117) and turn south.[13]

Within the preserve, the river meanders between hills amidst woodland interrupted by large clearings. Small stone bridges carry several of the preserve's trails across the river. About 600 feet (180 m) after entering the preserve, the Pocantico crosses into the village of

Old Croton Aqueduct, a National Historic Landmark (NHL), and leaves the preserve, continuing straight through a steep, narrow wooded ravine in a slightly southwesterly direction.[12]

As it flows between Sleepy Hollow Cemetery to the west and the village's Douglas Park to the east, the river drops below 50 feet (15 m) in elevation. On the north edge of another residential neighborhood, it bends eastward. After flowing under U.S. Route 9, it is again impounded, creating the mill pond at the Philipsburg Manor House, another NHL.[14][15]

From that outlet, it meanders northwest past the former

Empire Service, it flows under the entrance road to the county's Kingsland Point Park and empties into the Hudson River.[14][15]

Watershed

The Pocantico's 16-square-mile (41 km2)

Ossining, Mount Pleasant, and New Castle, including Briarcliff Manor and Sleepy Hollow.[16] It includes 436 acres (176 ha) of mapped freshwater wetlands and eleven dams. Approximately 14,866 people live within the watershed. It is largely suburban, but also contains parks, forests and wildlife, highways, utilities, and institutions.[17]

History

Painting of a forest, stream, and mill
Carl's Mill on the Pocantico River, Sleepy Hollow by William Rickarby Miller in 1851, depicting a small mill on the river that was one of the ancient landmarks of the Sleepy Hollow; it vanished some time before 1893.[a][19]

The

Dobbs Ferry, also had a village at the mouth of the Pocantico River called Alipconck, meaning "place of elms".[20]: 11, 31  The river historically set the dividing line between Mount Pleasant and Ossining.[20]

The river was once called by the English as "the Mill river", while the Native Americans called it Pocanteco, a derivative of the Algonquin term Pockóhantès, meaning a "run between two hills". The Dutch called it the Sleepy haven kill.

country seat at what was then known as North Tarrytown, at the mouth of the Pocantico River. A small community had already been established there when he arrived in 1683.[24]

A ship called the Roebuck, which transported cargo to and from New York City, ended up in the river, where its keel was scavenged by the miller at the mill of the Philipsburg Manor House site.[21]: 328 

Around the late 1890s, Walter W. Law and Briarcliff Farms deepened the river for a length of 2 miles (3 km), taking out the rifts so the stream would flow and the swamps adjacent to the river would drain. The workers also cut rock and took out trees that lined the swamps to reclaim land for farming.[25]

The North Tarrytown Assembly, a large automobile factory in Sleepy Hollow, was owned and operated by General Motors for much of its history; a 1923 expansion of the facility involved land-filling the river; two-thirds of the factory site was land formerly occupied by the river. The river was rerouted south of the site.[26]

During 1999's Hurricane Floyd, the Pocantico was blocked by fallen trees and almost washed away the Philipsburg Manor historic site; about 70 employees of the parent organization Historic Hudson Valley assisted in its protection, along with the site's curators and security guards, and other village residents.[27]

Ecology and environment

beach advisories for the entire river.[4] In 2014, $9.9 million was put aside to repair the Tarrytown sewage treatment plant in order to improve water quality in the region.[32]

A Westchester County water quality study of the Pocantico River found that the chemical pollutants in the water met most of New York State Standards. The river met state standards on

cultural eutrophication in the water. Dissolved oxygen levels also met state standards with an average concentration of 9.853 milligrams per liter. Only the conductivity of the water failed state standards with conductivity levels averaging about three times the recommended levels.[3]

American eels enters the river from the Hudson every spring, moving upstream over the course of one to three years. The eels often accumulate under a dam in Sleepy Hollow, and approximately 10% make it past the dam. The eels move upstream where the habitat is preferable, with lower polychlorinated biphenyl pollution, fewer parasites, faster growth rates for the eels, and a higher percentage of females in the population. Other species in the river include white perch, white sucker, yellow perch, golden shiner, and alewife, only in small numbers.[33]

Adjacent to the river is a protected area known as Pocantico Lake Park. The park contains hiking trails as well as an abandoned water treatment plant from the New Rochelle Water Company.

In popular culture

William Rockefeller funded U.S. Route 9's current bridge over the Pocantico in 1912.[41]

The

dénouement of "The Legend of Sleepy Hollow" is set at a bridge over the Pocantico River in the area of the Old Dutch Church and Burying Ground in Sleepy Hollow.[42][b] As well, Washington Irving makes frequent mention of the Pocantico River in Chronicle III of his short story anthology Wolfert's Roost.[43]

The delighted historian pursued his explorations far into the foldings of the hills where the Pocantico winds its wizard stream among the mazes of its old Indian haunts; sometimes running darkly in pieces of woodland beneath balancing sprays of beech and chestnut: sometimes sparkling between grassy borders in fresh green intervals; here and there receiving the tributes of silver rills which came whimpering down the hill sides from their parent springs. In a remote part of the Hollow, where the Pocantico forced its way down rugged rocks, stood Carl's mill, the haunted house of the neighborhood.

  1. ^ The mill was described as a ruin in 1899.[18]
  2. ^ The bridge is presumed to be part of the Albany Post Road, now part of U.S. Route 9; at least five bridges are known to have stood there.[42]
