River in New York, United States

The Hutchinson River is a 10 mile long (16 km) freshwater stream located in the New York City borough of the Bronx and Southern Westchester County, New York, United States. It forms on the New Rochelle–Scarsdale municipal line off Brookline Road in the latter community and flows south, draining a 19.4 square miles (50 km2) area. It continues to serve as New Rochelle's city line with Eastchester; further downstream; its lower reaches divide Mount Vernon and Pelham until it enters the Bronx and empties into Long Island Sound's Eastchester Bay. The river is named for Anne Hutchinson, who came from Rhode Island in 1642 and settled on Pelham Neck to the east of the river, across from where Co op City is now. Much of the land in the Hutchinson's watershed has been extensively developed over the last century as the New York metropolitan area grew and suburbanized. Along all but its uppermost and lowermost stretches, it is paralleled by the Hutchinson River Parkway. At three points along its length it has been dammed to create reservoirs. Its lower three miles (5 km) are commercially navigable and still in use by shipping. As a result of all this pressure, the river is seriously polluted. The New York State Department of Environmental Conservation rates the entire stream as impaired to an extent that it cannot be used as drinking water or recreationally; local authorities discourage eating any fish caught from the Hutchinson. Efforts to clean up the river have begun both in the form of remediation programs and lawsuits against polluters.

The main stem of the Hutchinson rises from a confluence of two short streams off Brookline Road in an extensively developed residential area of single family homes on large lots in Scarsdale, at an elevation roughly 71.63 m above sea level. From its source the river serves as the boundary between Scarsdale and the city of New Rochelle to the east. It flows southwesterly, heavily channelized, between backyards 121.92 m to its first crossing, a street known as Drake Road in Scarsdale and Baraud Road in New Rochelle. Below the bridge, the Hutchinson continues winding, still decoratively channelized and with several small wooden private pedestrian bridges, through the backyards of houses on the east side of Forest and East Woods lanes on the Scarsdale side. Sloping woodland buffers the backyards, on Abington Lane and Tewkesbury Road in New Rochelle. A little over a half mile (800 m) south of the bridge, the river enters a larger patch of woods south of the Tunstall Road dead end in Scarsdale, west of Primrose Road in New Rochelle. After winding another 213.36 m to the south, the Hutchinson bends southeastward to where Scarsdale Boulevard (just Boulevard in Scarsdale) crosses. From there it soon returns to its southwest course as it flows 243.84 m through another wooded area between houses to its next crossing, Sprague Road. Another 152.40 m below that bridge, as the river again divides houses in the narrowing space between Clarence Road on the west and Charlotte Lane to the east, it becomes the boundary between New Rochelle and Eastchester. It then bends more to the southwest, paralleling Wilmot, as it enters a 300 feet (91 m) culvert carrying it under Old and New Wilmot roads. Another quarter mile downstream, with wooded strips buffering it on either side, it crosses under Lakeshore Drive and then widens into Reservoir No. 1, or Lake Innisfree. At the V shaped lake the Hutchinson has descended to 56.08 m. It flows out through a narrow spillway on the lake's southeastern shore, crossing under a footbridge and then immediately bending southwest to begin several miles of closely paralleling the Hutchinson River Parkway, a four lane limited access grade separated highway. The river goes through a series of culverts under the ramps of the parkway's Mill Road exit immediately to the south. While still flowing close by the parkway, it enters the mostly wooded Twin Lakes County Park, the least developed area it has flowed through by this point.

Approximately 0.3 mile (0 km) downstream of Lake Innisfree, the Hutchinson opens up into Reservoir 3, having descended to 37.49 m in elevation. Another quarter mile to the south, it flows out of the lake via a spillway in the dam at its southern end, then crosses under a park road and then the parkway for the first of several times, just south of the Webster Avenue exit. From there it continues flowing, first through a small unnamed lake, slightly to the southwest through the wooded parkland to the Reservoir 2, 28.96 m above sea level. The Hutchinson gets to its greatest distance from the parkway here, 228.60 m to its east at one point over the river's next , before returning to cross under the road and flow southwest again just north of the Pelhamdale Road exit. Just before it flows under New Rochelle Road, the border of that community leaves the river channel. South of that bridge, it enters Mount Vernon and after another 1000 feet (305 m) again forms a municipal boundary, between Mount Vernon and the village of Pelham, once it crosses under the exit ramps for the southbound parkway.

Remaining within the narrow strip of woodland between the parkway and Hutchinson Boulevard to the west, the river bends a bit more towards the south over its next 0.3 mile (0 km) to the Cross County Parkway connector, where it goes through a 350 feet (107 m) culvert. After emerging, it remains in the much narrower space between the roads for another thousand feet to where it flows through another culvert under the parkway to its east side, paralleling River Avenue briefly before it flows under East Lincoln Avenue and the offramps for that exit, then a footbridge next to the intersection of First Avenue and Third Street, before crossing under the parkway again and turning south into Pelham Lake, 13.11 m above sea level, in Willson's Woods Park. At the south end of the 800 feet (244 m) lake, the Hutchinson flows over a small stone dam and then under the parkway again. On the other side, the river turns southwest again, flows under the railroad tracks used by Metro North Railroad's New Haven Line commuter service. After 60.96 m, it turns and is again crossed by the parkway, having descended to 8.23 m above sea level. The river, closely paralleling the parkway, bends to the south over its next thousand feet to where East Third Street and the offramp to it from the parkway cross over. Immediately to the south it borders Mount Vernon's small Migui Park. Another thousand feet downstream, after the river and parkway curve slightly southwest again, Colonial Avenue crosses over. At this point Pelham Manor becomes the village on the east of the river. A hundred feet (30 m) to the south, bending more to the west briefly, the Hutchinson crosses under three roadways: the ramps between Colonial and the southbound parkway, and the access road to the Glover athletic complex to the south. The river again flows southwest, and another hundred feet downstream a footbridge from the parking lot to the fields crosses over. The Hutchinson diverges from the parkway's side over the next 0.3 mile (0 km), flowing 500 feet (150 m) to its east as the fields and tennis courts interpose themselves. On the river's west, land use changes to commercial. South of the Glover complex the Hutchinson widens, bears more to the southwest, further away from the parkway, and enters an industrial area, with tank farms and warehouses aside. This the upper limit of commercial navigation on the river, and a thousand feet into it a 500 foot terminal branches off to the northwest. Another 106.68 m to the south Pelham Parkway (South Fulton Avenue in Mount Vernon) crosses on a steel mesh drawbridge. And 300 feet (100 m) south of that bridge, a pipeline is elevated high above the river bed. The river veers slightly into a straight south southwest course, now wide enough that barges can moor along its banks, and 500 feet from the pipeline it is briefly entirely within Mount Vernon as Pelham Manor gives way to the New York City borough of The Bronx on the east side. After 200 feet (120 m), the Hutchinson crosses the city limit itself.

Two hundred feet into the Bronx neighborhood also known as Eastchester, the Hutchinson bends southeast as another 500 foot terminal extends to the west northwest. Another 200 feet downstream, Boston Road (U. S. Route 1) crosses over on the four lane Eastchester Bridge. The river bends slightly and then back over its next thousand feet, growing wider just above where the New England Thruway (Interstate 95) crosses over. South of the Thruway, the Hutchinson bends again to a south southwest course, now a hundred feet wide, flowing straight between an industrial area on its west and wetlands on the east, part of the Thomas Pell Wildlife Sanctuary in nearby Pelham Bay Park. The parkway returns to the river's vicinity, paralleling it 500 feet to the west. A thousand feet south of the Thruway the industrial properties give way to the Co op City housing development. After flowing past Co Op City for , the Hutchinson, now below 3.05 m in elevation, with a dredged channel in its middle, bends southeast as the parkway crosses for the last time. Immediately downstream, the river widens into an estuary, with tidal flats on its eastern shore and housing projects on its west, with small Goose Island just offshore. Another downstream from the parkway, the Pelham Bay Bridge carries Amtrak's Northeast Corridor passenger service over the river. A small bay protrudes on the south side of the river, and 500 feet downstream the 891 feet (272 m) Pelham Bridge, the lowest bridge on the Hutchinson, carries Shore Road across. Below the bridge the Hutchinson widens into its mouth, becoming Eastchester Bay near the west end of Long Island Sound, with the Country Club neighborhood on its west and Rodman's Neck and City Island on the east.

The Hutchinson's 19.4 square miles (50 km2) watershed generally extends for a mile (1.6 km) to the Bronx River watershed on its west. On the river's east there is less distance, generally a half mile (800 m), to the Mamaroneck–Sheldrake watershed, reaching nearly a mile into New Rochelle near Pelham Lake. The United States Coast Guard closed the river to navigation fora a day after an April 1967 accident, when a tanker began leaking gasoline after striking a submerged obstacle. The leak was not discovered until it reached its terminal at Edison Avenue in Mount Vernon shortly afterwards. Anti combustion foam was sprayed on the river.

Six bridges span the river's navigable section, carrying rail and automobile traffic. They are, from downstream heading upstream: Pelham Bridge (movable), Amtrak's Pelham Bay Bridge (movable), Hutchinson River Parkway (movable), New England Thruway (fixed), and Eastchester Bridge (Boston Post Road) (fixed), in the Bronx; and Fulton Avenue Bridge in Pelham Manor (movable). The movable bridges still employ tenders and open daily for maritime traffic.

The New Rochelle Water Company dammed the Hutchinson River at three places between 1886 and 1907, creating three reservoirs at the northern end of the community. The Westchester County Park Commission purchased the reservoirs and the surrounding water shed property in 1927, for parkland and parkway purposes. A part of the land was used for the Hutchinson River Parkway, which follows the river for most of its distance. The three reservoirs are numbered in the order they were built. Reservoir No. 1, which is now known as Lake Innisfree, is furthest upstream, and was constructed in 1886. Lake Innisfree is the largest of the reservoirs. It is mostly surrounded by private land, but its dam and part of its eastern shore can be accessed on foot by the Leatherstocking Trail. The Hutchinson River runs about .75 mile (1 km) from Lake Innisfree to the northern reaches of Reservoir 3, constructed in 1907. Immediately after exiting Reservoir 3 the river flows under the Hutchinson River Parkway and then only about to Reservoir 2, which was constructed in 1892 and is the smallest of the three. Reservoir 3 and Reservoir 2 are both contained within Twin Lakes County Park and are accessible by the Leatherstocking Trail and other trails. The three reservoirs are no longer used as a water supply.

The southern part of Hutchinson River has become polluted due to outflow of raw sewage from Mount Vernon. Plumes of polluted water have flowed downstream and negatively impacted the river's fish population. This issue was first noted in 2003, prompting a cleanup directive from the EPA. The town faced several fines by 2017, having not taken action to mitigate pollution for two decades, and in 2020, received a federal court order calling for compliance with the Clean Water Act. A project to repair the broken sewage collection line in Mount Vernon, funded by the New York State Department of Environmental Conservation, was underway as of May 2023. In 2010, the Hutchinson River Restoration Project, a nonprofit organization, began working on volunteer led restoration efforts to help protect the river and its habitat.
