Paterson’s raceways are among the most important surviving physical reminders of the city’s industrial past. For more than a century, they carried water from the Passaic River to factories surrounding the Great Falls, providing the mechanical power that helped make Paterson one of America’s great manufacturing centers.
When the factories eventually stopped relying on waterpower, the raceways faced an uncertain future. Some sections were abandoned, altered or covered, while others survived because of their continuing importance to the historic landscape.
Today, preserving the raceways is an essential part of preserving Paterson’s industrial history.
From Working Infrastructure to Historic Resource
During the nineteenth century, nobody thought of the raceways primarily as historic structures.
They were working infrastructure.
The channels had to be maintained so that manufacturers could receive their waterpower. Gates had to function, channels had to remain clear, and structures had to withstand the constant pressure of moving water.
As steam and electricity replaced direct waterpower, the economic reason for maintaining many portions of the system disappeared.
Factories closed or converted to other sources of energy.
The raceways gradually changed from essential industrial infrastructure into historic resources.
The Threat of Abandonment
Once waterpower was no longer essential to manufacturing, portions of the raceway system were vulnerable to neglect.
Problems included:
- deterioration of masonry
- leaks
- vegetation growth
- accumulated debris
- damaged gates
- erosion
- flooding
- inappropriate alterations
- sections being covered or filled
The raceways had been engineered for industrial use, not necessarily for centuries of preservation.
Without regular maintenance, even massive masonry channels could deteriorate.
Recognizing the Historical Importance
During the twentieth century, historians, preservationists and government agencies increasingly recognized that Paterson’s industrial history could not be understood by preserving only individual factory buildings.
The entire industrial landscape was important.
That landscape included:
- the Great Falls
- the Passaic River
- dams
- raceways
- gatehouses
- wheelhouses
- mill buildings
- tailraces
- factory foundations
- industrial streets
The raceways were particularly important because they physically connected the natural power source to the factories.
Without them, the story of how the Great Falls powered Paterson would be incomplete.
Raceways as Historic Engineering
The raceways are significant not simply because they are old.
They demonstrate the engineering techniques used to control water and produce mechanical power during the early development of American industry.
They show how engineers addressed problems involving:
- elevation
- water flow
- hydraulic pressure
- flood control
- power distribution
- industrial site planning
The system is therefore both a historical landscape and an engineering artifact.
Raceways and Historic Preservation
Preservation of the raceways became increasingly connected with efforts to preserve Paterson’s Great Falls and industrial district.
The establishment of historic districts and preservation programs helped protect portions of the industrial landscape.
The designation of Paterson Great Falls National Historical Park in 2009 was particularly significant.
The National Park Service now interprets the Great Falls, raceways and surrounding industrial resources as parts of a connected story of America’s industrial development.
The raceways are therefore no longer simply abandoned infrastructure.
They are nationally significant historic resources.
Raceway Park
An important milestone in preservation occurred with the creation of Raceway Park, which opened to the public in 1982.
The park provided public access to portions of the historic raceway system and demonstrated that the raceways could be preserved and interpreted as part of Paterson’s public landscape.
Rather than hiding the old industrial channels, preservation efforts made them part of the city’s visible history.
Preserving the Complete System
One of the greatest challenges in preserving the raceways is recognizing that they are an interconnected system.
Preserving one isolated section is not enough.
The historical meaning comes from the relationship between:
River
↓
Dam
↓
Upper Raceway
↓
Middle Raceway
↓
Lower Raceway
↓
Wheelhouses
↓
Factories
↓
Tailraces
Each element helps explain the others.
A raceway without its water-control structures can be difficult to understand.
A wheelhouse without its raceway loses its context.
A factory without its power system leaves visitors wondering how the building operated.
Preservation therefore needs to consider the entire network.
Documenting the Raceways
Historic documentation is another important part of preservation.
Maps, engineering drawings, photographs, deeds and industrial records can help establish:
- original raceway locations
- changes in alignment
- mill sites
- water rights
- gate locations
- wheelhouse locations
- changes in water levels
- industrial ownership
- modifications over time
Historical documentation is especially important because portions of the original system are no longer visible.
In some places, the surviving evidence may be archaeological rather than above ground.
Archaeology and the Hidden Raceways
Not every part of Paterson’s historic raceway system remains exposed.
Some sections have been covered, filled or incorporated into later construction.
Archaeological investigation can reveal evidence of:
- buried raceway walls
- foundations
- wheel pits
- tailraces
- water-control structures
- abandoned channels
This hidden infrastructure is part of the city’s industrial archaeological record.
Protecting it is important because future research techniques may reveal information that cannot be recovered from surviving buildings alone.
Water Management and Preservation
Preserving a raceway is different from preserving a dry stone wall.
Raceways were designed to carry water.
Water is therefore both the reason the raceways exist and one of the major threats to their survival.
Preservation requires careful management of:
- water infiltration
- drainage
- erosion
- flooding
- freeze-thaw cycles
- vegetation
- masonry deterioration
Engineers and preservation professionals must balance historic authenticity with the need to protect the structures.
Public Interpretation
Preservation is most successful when people understand what they are seeing.
A visitor standing beside a raceway may simply see a stone channel.
Interpretive signs, maps and diagrams can explain what happened there.
A good interpretation program should show:
Where the water came from
↓
How it entered the raceway
↓
How it was controlled
↓
How it reached the mills
↓
How it powered machinery
↓
Where the water went afterward
This turns the raceway from an interesting old structure into an understandable piece of industrial technology.
Preserving the Story of the Workers
Raceway preservation should also include the human history associated with the system.
The raceways powered factories where generations of people worked.
Those workers included:
- machinists
- mill operators
- silk workers
- mechanics
- engineers
- laborers
- immigrants
- women and children employed in some industries
The raceways therefore connect the physical infrastructure to Paterson’s social and labor history.
Preserving the raceways helps preserve the places where these stories unfolded.
The Raceways and Paterson’s Industrial Identity
The raceways are central to understanding why Paterson developed where it did.
The city was not simply built beside a beautiful waterfall.
It was deliberately developed around an industrial power resource.
The raceways transformed that resource into usable energy.
They attracted factories.
The factories attracted workers.
The workers helped create neighborhoods and communities.
The resulting industrial city became famous for textiles, silk, locomotives, firearms and machinery.
Preserving the raceways therefore means preserving one of the fundamental reasons Paterson became Paterson.
Preservation for Future Generations
The raceways have survived for more than two centuries because each generation made choices about what to maintain and what to remove.
Future generations will face the same responsibility.
Preservation does not necessarily mean returning the raceways to their nineteenth-century operating condition.
Instead, it means:
- protecting surviving structures
- documenting lost sections
- stabilizing deteriorated masonry
- maintaining public access where appropriate
- interpreting the engineering system
- protecting archaeological resources
- connecting the raceways with surviving industrial buildings
The goal is to preserve both the physical structures and their historical meaning.
A Historic Power Network
The raceways can be thought of as Paterson’s first industrial utility network.
They were designed to do something remarkably similar to a modern power grid:
Collect energy → control energy → distribute energy → deliver energy to users.
The technology was different, but the concept was sophisticated.
Preserving the raceways allows modern visitors to see how an early American industrial city solved the problem of distributing power before electricity existed.
The Raceways as Paterson’s Industrial Legacy
The raceways are more than old channels carrying water.
They are the surviving infrastructure of a technological system that helped transform a natural waterfall into an industrial power source.
They connected the Passaic River with the factories of Paterson.
They powered machines.
They supported industries.
They provided employment.
They helped attract immigrants.
They contributed to the development of the Silk City.
And they remain today as physical evidence of that extraordinary transformation.
The factories may be silent.
The waterwheels may be gone.
The machinery may have disappeared.
But the raceways remain.
Preserving them ensures that future generations can still follow the path of the water and understand how the Great Falls helped build Paterson.
