The Connecticut River is the longest river in the New England region of the United States, flowing roughly southward for 406 miles (653 km) through four states. It rises at the U.S. border with Quebec, Canada and discharges at Long Island Sound.[3] Its watershed encompasses five U.S. states and one Canadian province, 11,260 square miles (29,200 km2) via 148 tributaries, 38 of which are major rivers.[4] It produces 70% of Long Island Sound's fresh water, discharging at 19,600 cubic feet (560 m3) per second.[4][5]

The Connecticut River Valley is home to some of the northeastern United States' most productive farmland, as well as a metropolitan region of approximately two million people surrounding Springfield, Massachusetts and Hartford, Connecticut.[6]


The word "Connecticut" is a French corruption of the Mohegan word quinetucket which means "beside the long, tidal river".[7] The word came into English during the early 1600s to name the river, which was also called simply "The Great River".[8]

Pre-1614–1637: American Indian populations

Prior to Dutch exploration beginning in 1614, numerous indigenous tribes lived throughout the fertile Connecticut River valley. Information concerning how these tribes lived and interacted stems mostly from English accounts written during the 1630s.[9]

The Pequots dominated a territory in the southernmost region of the Connecticut River valley, stretching roughly from the river's mouth at Old Saybrook, Connecticut northward to just below the Big Bend at Middletown. They warred with and attempted to subjugate neighboring agricultural tribes such as the Western Niantics, while maintaining an uneasy stand-off with their rivals the Mohegans.[10] The Mattabesset (Tunxis) tribe takes its name from the place where its sachems ruled at the Connecticut River's Big Bend at Middletown, in a village sandwiched between the territories of the aggressive Pequots to the south and the more peaceable Mohegans to the north.[11]

The Mohegans dominated the region due north, where Hartford and its suburbs sit, particularly after allying themselves with the Colonists against the Pequots during the Pequot War of 1637.[12] Their culture was similar to that of the Pequots, as they had split off from them and become their rivals some time prior to European exploration of the area.[12] The agricultural Pocomtuc tribe lived in unfortified villages alongside the Connecticut River north of the Enfield Falls on the fertile stretch of hills and meadows surrounding Springfield, Massachusetts. The Pocomtuc village of Agawam[13] eventually became Springfield, situated on the Bay Path where the Connecticut River meets the western Westfield River and eastern Chicopee River.[14] The Pocomtuc villagers at Agawam helped Puritan explorers settle this site and remained friendly with them for decades, unlike tribes farther north and south along the Connecticut River.[15][16] The region stretching from Springfield north to the New Hampshire and Vermont state borders fostered many agricultural Pocomtuc and Nipmuc settlements, with its soil enhanced by sedimentary deposits. Occasionally, these villages endured invasions from more aggressive confederated tribes living in New York, such as the Mohawk, Mahican, and Iroquois tribes.[15][16]

The Pennacook tribe mediated many early disagreements between colonists and other Indian tribes, with a territory stretching roughly from the Massachusetts border with Vermont and New Hampshire, northward to the rise of the White Mountains in New Hampshire.[17] The Western Abenaki (Sokoki) tribe lived in the Green Mountains region of Vermont but wintered as far south as the Northfield, Massachusetts area. They later merged with members of other Algonquin tribes displaced by wars and famines.[18]

1614–1636: Dutch and Puritan settlement

In 1614, Dutch explorer Adriaen Block became the first European to chart the Connecticut River, sailing as far north as Enfield Rapids.[19] He called it the "Fresh River" and claimed it for the Netherlands as the northeastern border of the New Netherland colony. In 1623, Dutch traders constructed a fortified trading post at the site of Hartford, Connecticut called the Fort Huys de Hoop ("Fort House of Hope").[20]

Four separate Puritan-led groups also settled the fertile Connecticut River Valley, and they founded the two large cities that continue to dominate the Valley today: Hartford (est. 1635) and Springfield (est. 1636). The first group of pioneers left the Plymouth Colony in 1632 and ultimately founded the village of Matianuck (which became Windsor, Connecticut) several miles north of the Dutch fort. A group left the Massachusetts Bay Colony from Watertown, seeking a site where they could practice their religion more freely. With this in mind, they founded Wethersfield, Connecticut in 1633, several miles south of the Dutch fort at Hartford.

In 1635, Reverend Thomas Hooker led settlers from Cambridge, Massachusetts, where he had feuded with Reverend John Cotton, to the site in Connecticut of the Dutch Fort House of Hope, where he founded Newtowne.[20] Shortly after Hooker's arrival, Newtowne annexed Matianuck based on laws articulated in Connecticut's settlement charter, the Warwick Patent of 1631. The patent, however, had been physically lost, and the annexation was almost certainly illegal.[21]

The fourth English settlement along the Connecticut River came out of a 1635 scouting party commissioned by William Pynchon to find the most advantageous site for commerce and agriculture, hoping to found a city there. His scouts located the Pocumtuc village of Agawam, where the Bay Path trade route crossed the Connecticut River at two of its major tributaries—the Chicopee River to the east and Westfield River to the west—and located just north of Enfield Falls, the river's first unnavigable waterfall. Pynchon surmised that traders using any of these routes would have to dock and change ships at his site, thereby granting the settlement a commercial advantage.[22] It was initially named Agawam Plantation and was allied with the settlements to the south that became the state of Connecticut, but it switched allegiances in 1641 and was renamed Springfield in honor of Pynchon's native town in England.[22]

Of these settlements, Hartford and Springfield quickly emerged as powers. In 1641, Springfield splintered off from the Hartford-based Connecticut Colony, allying itself with the Massachusetts Bay Colony. For decades, Springfield remained the Massachusetts Bay Colony's westernmost settlement, on the northern border of the Connecticut Colony. By 1654, however, the success of these English settlements rendered the Dutch position untenable on the Connecticut River. A treaty moved the boundary westward between the Connecticut Colony and New Netherland Colony to a point near Greenwich, Connecticut. The treaty allowed the Dutch to maintain their trading post at Foot Huys de Hoop, which they did until the 1664 British takeover of New Netherland.

Border disputes

The Connecticut River Valley's central location, fertile soil, and abundant natural resources made it the target of centuries of border disputes, beginning with Springfield's defection from the Connecticut Colony in 1641, which brought the Massachusetts Bay Colony to the river. Conflicting royal treaties of 1764 sparked the river's east-siders to unite with Ethan Allen and the west-siders against New York and the British. The 1783 Treaty of Paris created a disputed border with Canada from the Connecticut's "northernmost headwaters". A 1933 U.S. Supreme Court decision settled a contentious boundary dispute[23] between Vermont and New Hampshire. The Connecticut River's history is characterized by both political intrigue and technological innovation.[24]

During 1640 and 1641, two controversies took place that altered the political boundaries of the Lower Connecticut River region, preventing it from administration by a single political body. The Connecticut Colony administered Springfield during the 1630s, in addition to Hartford, Wethersfield, and Windsor; however, by 1640, Springfield's advantageous geography enabled it to become the Connecticut Colony's most commercially prosperous settlement. The Colony endured a crippling grain shortage during the spring of 1640 which caused many cattle to die of starvation. The grain shortage became a matter of survival for the Colony but not for Springfield, due to its prosperity.[22]

In response to the shortage, leading citizens of Wethersfield and Hartford gave power to Pynchon, Springfield's founder, to purchase corn for all of the Connecticut Colony's settlements from the Pocumtuc. Colony leaders authorized him to offer large sums of money to the Indians, far above market prices; however, the Indians refused to sell at even "reasonable" prices, and thus he refused to buy the corn altogether. Pynchon argued that it was best not to broadcast the Connecticut Colonists' weaknesses to the Indians, who he believed might capitalize on it; likewise, he aimed to keep market values and trade with the Indians steady in the future.[22]

Hartford's leading citizens were furious with Pynchon's willingness to further imperil the starving settlements. With Windsor's and Wethersfield's consent, they commissioned Captain John Mason who had fought in the Pequot War to travel to Springfield with "money in one hand and a sword in the other" to make a deal with the Indians, and also to rebuke Pynchon.[22] On reaching Springfield, Mason threatened the Indians with war if they did not sell their corn at reasonable prices. The Indians capitulated and ultimately sold the corn to the Colonists. However, Mason's violent approach aroused distrust among the Pocumtuc tribe. Mason also upbraided Pynchon in public.[22] This incident arose partly from differences of opinion regarding how to interact with the Indian tribes. Pynchon had achieved mutual benefits by trading with the Pocumtucs, whereas Mason had used force. Nevertheless, it caused Springfield's settlers to rally around the humiliated Pynchon, and led to the settlement severing ties with the Connecticut Colony.[22]

As this controversy was heating up, the Massachusetts Bay Colony saw an opportunity to gain a foothold along the fertile Connecticut River Valley. In 1640, Boston asserted a claim to jurisdiction over lands surrounding the river; however, Springfield remained politically independent until tensions with the Connecticut Colony were exacerbated by a final confrontation later that year.[22]

Hartford kept a fort at the mouth of the Connecticut River at Old Saybrook for protection against the Pequots, Wampanoags, Mohegans, and the New Netherland Colony. After Springfield broke ties with the Colony, the remaining Connecticut settlements demanded that Springfield's ships pay tolls when passing the mouth of the river. The ships refused to pay this tax without representation at Connecticut's fort, but Hartford refused to grant it. In response, the Massachusetts Bay Colony solidified its friendship with Springfield by levying a toll on Connecticut Colony ships entering Boston Harbor. Connecticut was largely dependent on sea trade with Boston and therefore permanently dropped its tax on Springfield, but Springfield allied with Boston nonetheless, drawing the first state border across the Connecticut River.[22]

The Fort at Number 4 in Charlestown, New Hampshire was the northernmost English settlement on the Connecticut River until the end of the French and Indian War in 1763. Abenaki Indians resisted British attempts at colonization, but Colonists began settling north of Brattleboro, Vermont following the war.[25] Settlement of the Upper Connecticut River Valley increased quickly, with population assessments of 36,000 by 1790.[25]

The area that is now Vermont was claimed by both New Hampshire and New York, and was settled primarily through the issuance of land grants by New Hampshire Governor Benning Wentworth beginning in the 1740s.[26] New York protested these grants, and King George III decided in 1764 that the border between the provinces should be the western bank of the Connecticut River.[27] Ethan Allen, the Green Mountain Boys, and other residents of the disputed area resisted attempts by New York to exercise authority over the area, which resulted in the establishment of the independent Vermont Republic in 1777[28] and its eventual accession to the United States in 1791 as the fourteenth state.[29] Boundary disputes between Vermont and New Hampshire lasted for nearly 150 years and were finally settled in 1933, when the U.S. Supreme Court reaffirmed King George's boundary as the ordinary low-water mark on the Vermont shore. In some places, the state line is now inundated by the impoundments of dams built after this time.[30]

The Treaty of Paris and the 19th century

The Treaty of Paris (1783) that ended the American Revolutionary War created a new international border between New Hampshire and the Province of Canada at "northwesternmost headwaters of the Connecticut". Several streams fit this description, and thus a boundary dispute led to the short-lived Indian Stream Republic, which existed from 1832 to 1835.

The Windsor Locks Canal Company at Enfield Falls, the Connecticut River's first major barrier to navigation

The broad, fertile Connecticut River Valley attracted agricultural settlers and colonial traders to Hartford, Springfield, and the surrounding region. The high volume and numerous falls of the river led to the rise of industry along its banks during the Industrial Revolution. The cities of Springfield and Hartford in particular became centers of innovation and "intense and concentrated prosperity."[31]

The Enfield Falls Canal was opened in 1829 to circumvent shallows around Enfield Falls, and the locks built for this canal gave their name to the town of Windsor Locks, Connecticut.[32] The Connecticut River Valley functioned as America's hub of technical innovation into the 20th century, particularly the cities of Springfield and Hartford, and thus attracted numerous railroad lines. The proliferation of the railroads in Springfield and Hartford greatly decreased the economic importance of the Connecticut River. From the late 1800s until today, it has functioned largely as a center of wildlife and recreation.[33]

Log drives and the early 20th century

The Oxbow, Connecticut River, circa 1910

Starting about 1865,[34] the river was used for massive logging drives from Third Connecticut Lake to initially water powered sawmills near Enfield Falls. Trees cut adjacent to tributary streams including Perry Stream and Indian Stream in Pittsburg, New Hampshire, Halls Stream on the Quebec–New Hampshire border, Simms Stream, the Mohawk River, and the Nulhegan River basin in Essex County, Vermont, would be flushed into the main river by the release of water impounded behind splash dams. Several log drivers died trying to move logs through Perry Falls in Pittsburg. Teams of men would wait at Canaan, Vermont, to protect the bridges from log jams. Men guided logs through a 400-foot (120 m) drop along the length of Fifteen-Mile Falls[34] (now submerged under Moore and Comerford reservoirs), and through Logan's Rips at Fitzdale, Mulligan's Lower Pitch, and Seven Islands. The White River from Vermont and Ammonoosuc River from New Hampshire brought more logs into the Connecticut. A log boom was built between Wells River, Vermont, and Woodsville, New Hampshire, to hold the logs briefly and release them gradually to avoid jams in the Ox Bow. Men detailed to this work utilized Woodsville's saloons and red-light district.[35] Some of the logs were destined for mills in Wilder and Bellows Falls, Vermont, while others were sluiced over the Bellows Falls dam. North Walpole, New Hampshire, contained twelve to eighteen saloons, patronized by the log drivers.[36] Mount Tom was the landmark the log drivers used to gauge the distance to the final mills near Holyoke, Massachusetts.[37] These spring drives were stopped after 1915, when pleasure boat owners complained about the hazards to navigation.[38] The final drive included 500 workers controlling 65 million feet of logs.[34] A final pulp drive consisted of 100,000 cords of four-foot logs in 1918. This was to take advantage of the wartime demand.[34]

The flood of 1936

In March 1936, due to a winter with heavy snowfall, an early spring thaw and torrential rains, the Connecticut River flooded, overflowing its banks, destroying numerous bridges and isolating hundreds of people who had to be rescued by boat.

The dam at Vernon, Vermont, was topped by 19 feet (5.8 m). Sandbagging by the National Guard and local volunteers helped prevent the dam's powerhouse from being overwhelmed, despite blocks of ice breaking through the upstream walls.[39]

In Northampton, Massachusetts, looting during the flood became a problem, causing the mayor of the city to deputize citizen patrols to protect flooded areas. Over 3,000 refugees from the area were housed in Amherst College and the Massachusetts State Agricultural College (now UMass Amherst).

Unprecedented accumulated ice jams compounded the problems created by the flood, diverting water into unusual channels and damming the river, raising water levels even further. When the jam at Hadley, Massachusetts, gave way, the water crest overflowed the dam at Holyoke, overwhelming the sandbagging there. The village of South Hadley Falls was essentially destroyed, and the southern parts of Holyoke were severely damaged, with 500 refugees.

Downtown Hartford, Connecticut, during the 1936 flood

In Springfield, Massachusetts, 5 sq mi (13 km2), and 18 miles (29 km) of streets, were flooded, and 20,000 people lost their homes. The city lost power, and nighttime looting caused the police to issue a "shoot on sight" edict; 800 National Guard troops were brought in to help maintain order. Rescue efforts using a flotilla of boats saved people trapped in upper stories of buildings, bringing them to local fraternal lodges, schools, churches and monasteries for lodging, medical care, and food. The American Red Cross and local, state and Federal agencies, including the WPA and the CCC, contributed aid and manpower to the effort. Flooding of roads isolated the city for a time. When the water receded, it left behind silt-caused mud which in places was 3 feet (1 m) thick; the recovery effort in Springfield, at the height of the American Great Depression, took approximately a decade.

Overall, the flood caused 171 deaths and US$500 million (US$8,800,000,000 with inflation[40]) in damages. Across the northeast, over 430,000 people were made homeless or destitute by flooding that year.[41]

The Connecticut River Flood Control Compact between the states of Connecticut, Massachusetts, New Hampshire, and Vermont was established in 1953 to help prevent serious flooding.[42]

1936–present: Water supply

The creation of the Quabbin Reservoir in the 1930s diverted the Swift River, which feeds the Chicopee River, a tributary of the Connecticut. This resulted in an unsuccessful lawsuit by the state of Connecticut against the diversion of its riparian waters.[43]

Demand for drinking water in eastern Massachusetts passed the sustainable supply from the existing system in 1969. Diverting water from the Connecticut River was considered several times,[44] but in 1986 the Massachusetts Water Resources Authority instead undertook a campaign of water conservation. Demand was reduced to sustainable levels by 1989, reaching approximately a 25% margin of safety by 2009.[45]


By far the largest river ecosystem in New England, the Connecticut River watershed spans five of the six New England states – New Hampshire, Vermont, Massachusetts, Connecticut, as well as small portions of Maine and the Canadian province of Quebec.[4][30][46]

The Connecticut River rises from the Fourth Connecticut Lake, a small pond that sits 300 yards (270 m) south of the U.S. national border with Chartierville, Quebec, Canada, in the town of Pittsburg, New Hampshire, United States. Beginning at an elevation of 2,670 feet (810 m) above sea level, the Connecticut River flows through the remaining Connecticut Lakes and Lake Francis – for 14-mile (23 km), all within the town of Pittsburg – and then widens as it delineates 255-mile (410 km) of the border between New Hampshire and Vermont.[46] The Connecticut drops more than 2,480 feet (760 m) in elevation as it winds south to the border of Massachusetts, at which point it sits 190 feet (58 m) above sea level.[30][47]

The region along the river upstream and downstream from Lebanon, New Hampshire and White River Junction, Vermont, is known locally as the "Upper Valley". The exact definition of the region varies, but it generally is considered to extend south to Windsor, Vermont, and Cornish, New Hampshire, and north to Bradford, Vermont, and Piermont, New Hampshire.[48]

The Middle Connecticut River: Massachusetts through central Connecticut

Following the most recent ice age, the Middle Connecticut River Valley sat at the bottom of Lake Hitchcock. Its lush greenery and rich, almost rockless soil comes from the ancient lake's sedimentary deposits.[49] In the Middle Connecticut region, the river reaches its maximum depth – 130 feet (40 m) – at Gill, Massachusetts, around the French King Bridge, and its maximum width – 2,100 feet (640 m) – at Longmeadow, directly across from the Six Flags New England amusement park.[30][50] The Connecticut's largest falls – South Hadley Falls – features a vertical drop of 58 feet (18 m).[4] Lush green forests and agricultural hamlets dot this middle portion of the Connecticut River; however, the region is best known for its numerous college towns, such as Northampton, South Hadley, and Amherst, as well as the river's most populous city, Springfield. The city sits atop bluffs beside the Connecticut's confluence with two major tributaries, the Chicopee River to the east and Westfield River to the west.[51]

The Connecticut River is influenced by the tides as far north as Enfield Rapids in Windsor Locks, Connecticut, approximately 58 miles (93 km) north of the river's mouth. Two million residents live in the densely populated Hartford-Springfield region, which stretches roughly between the college towns of Amherst, Massachusetts, and Middletown, Connecticut. Hartford, the Connecticut River's second largest city and only state capital, is located at the southern end of this region on an ancient floodplain that stretches to Middletown.

The Lower Connecticut River: Southern Connecticut to Long Island Sound

15 miles (24 km) south of Hartford, at Middletown, the Lower Connecticut River section begins with a narrowing of the river, and then a sharp turn southeast. Throughout southern Connecticut, the Connecticut passes through a thinly populated, hilly, wooded region before again widening and discharging into Long Island Sound between Old Saybrook and Old Lyme. Due to the presence of large, shifting sandbars at its mouth, the Connecticut is the only major river in the Northeastern United States without a port at its mouth.[52]

Mouth and tidelands

The Connecticut River carries a heavy amount of silt, especially during the spring snow melt, from as far north as Quebec. This heavy silt concentration manifests in a large sandbar near the Connecticut's mouth, which has, historically, provided a formidable obstacle to navigation. Due to the difficulty it presents to ships, the Connecticut is one of the few major rivers in the United States without a major city at its mouth. The Connecticut's major cities – Hartford and Springfield – lie 45 and 69 miles (70 and 110 km) upriver, respectively.

The Nature Conservancy named the Connecticut River's tidelands one of the Western Hemisphere's "40 Last Great Places", while the Ramsar Convention on Wetlands listed its estuary and tidal wetlands complex as one of 1,759 wetlands of international importance.[53]

In 1997, the Connecticut River was designated one of only 14 American Heritage Rivers, which recognized its "distinctive natural, economic, agricultural, scenic, historic, cultural and recreational qualities." In May 2012, the Connecticut River was designated America's first National Blueway, in recognition of the restoration and preservation efforts on the river.[6]


The Connecticut River's flow is slowed by main stem dams, which create a series of slow-flowing basins from Lake Francis Dam in Pittsburg, New Hampshire, to the Holyoke Dam at South Hadley Falls in Massachusetts.[4] Among the most extensively dammed rivers in the United States, the Connecticut may soon flow at a more natural pace, according to scientists at the University of Massachusetts at Amherst, who have devised a computer that – "in an effort to balance human and natural needs" – coordinates the holding and releasing of water between the river's 54 largest dams.[54]


The Connecticut River watershed encompasses 11,260 square miles (29,200 km2), connecting 148 tributaries, including 38 major rivers and numerous lakes and ponds.[6] Major tributaries include (from north to south) the Passumpsic, Ammonoosuc, White, Black, West, Ashuelot, Millers, Deerfield, Chicopee, Westfield, and Farmington rivers. The Swift River, a tributary of the Chicopee, has been dammed and largely replaced by the Quabbin Reservoir which provides water to the Massachusetts Water Resources Authority district in eastern Massachusetts, including Boston and its metropolitan area.

There are several species of anadromous and catadromous fish, including brook trout, winter flounder, blueback herring, alewife, rainbow trout, large brown trout, American shad (Alosa sapidissima), hickory shad, smallmouth bass, Atlantic sturgeon, striped bass (Morone saxatilis), carp, catfish, American eel, sea lamprey, and endangered shortnose sturgeon and dwarf wedgemussels.[55] Additionally, the United States Fish and Wildlife Service has repopulated the river with another species of migratory fish, the Atlantic salmon, which for more than 200 years had been extinct from the river due to damming.[55] Several fish ladders and fish elevators have been built to allow fish to resume their natural migration upriver each spring.

Much of the beginning of the river's course in the town of Pittsburg is occupied by the Connecticut Lakes, which contain lake trout and landlocked salmon. Landlocked salmon make their way into the river during spring spawning runs of bait fish and during their fall spawn. The river has fly-fishing-only regulations on 5 miles (8 km) of river. Most of the river from Lake Francis south is open to lure and bait as well. Two tail-water dams provide cold river water for miles downstream, making for bountiful summer fishing on the Connecticut.

After the first major dam was built near Turners Falls, Massachusetts, thirteen additional dams have ended the Connecticut River's great anadromous fish runs. Fish ladders constructed since the first fish passage in 1980 at Turners Falls, have enabled migrating fish to return to some of their former spawning grounds. In addition to dams, warm water discharges between 1978 and 1992 from Vermont Yankee Nuclear Power Plant in Vernon, Vermont released water up to 105 °F (41 °C) degrees and the thermal plume reached 55 miles (89 km) downstream to Holyoke. This thermal pollution appears to be associated with an 80% decline in American shad fish numbers from 1992 to 2005 at Holyoke dam. This decline may have been exacerbated by over-fishing in the mid-Atlantic and predation from resurging striped bass populations. The nuclear plant was closed at the end of 2014 but the 2015 shad run at Vernon numbered only 42,000 shad.[1]

There are 12 species of freshwater mussels.[56] Of those, 11 occur in the mainstem of the Connecticut, all but the brook floater, which is found only in small streams and rivers. Species diversity is higher in the southern part of the watershed (Connecticut and Massachusetts) than in the northern part (Vermont and New Hampshire), largely due to differences in stream gradient and substrate. Eight of the 12 species in the watershed are listed as endangered, threatened, or of Special Concern in one or more of the states in the watershed.[56]



The mouth of the river up to Essex is thought to be one of the busiest stretches of waterway in Connecticut. Some local police departments and the state Environmental Conservation Police patrol the area a few times a week. Some towns keep boats available if needed.[57] In Massachusetts, the most active stretch of the Connecticut River is centered on the Oxbow, 14 miles (23 km) north of Springfield in the college town of Northampton.[58]

Primitive camping is available along much of the river, for non-motorized boats, via the Connecticut River Paddlers' Trail. The Paddlers' Trail currently includes campsites on over 300 miles (480 km) of the river.[59]

Pollution and cleanup

The Water Quality Act of 1965 had a major impact on controlling water pollution in the Connecticut River and its tributaries.

Since then, the river has been restored from Class D to Class B (fishable and swimmable).[60][61] Many towns along the Lower Connecticut River have enacted a cap on further development along the banks, so that no buildings may be constructed except on existing foundations. Currently, a website provides water quality reports twice a week, indicating whether various portions of the river are safe for swimming, boating and fishing.[62][63]

The Connecticut River is a barrier to travel between western and eastern New England. Several major transportation corridors cross the river including Amtrak's Northeast Corridor, Interstate 95 (Connecticut Turnpike), Interstate 90 (Massachusetts Turnpike), Interstate 89, Interstate 93, and Interstate 84. In addition, Interstate 91, whose route largely follows the river north-south, crosses it twice – once in Connecticut and once in Massachusetts.
