Water Power and Industry
The Trenton Water Power
The Trenton Water Power was a seven-mile canal built in the early 1830s along the left bank of the Delaware River to spur industrial development along the waterfront in Trenton. The canal drew water from the Delaware via a wing dam at Scudders Falls, passed through downtown Trenton, and emptied back into the river below the falls at present-day Waterfront Park.
In 1831 the Trenton Delaware Falls Company incorporated and was authorized by the New Jersey Legislature to construct a dam in the Delaware River and a raceway into Trenton. The company sold stock, bought land and hired engineers Benjamin Wright, Stephen Long and Charles Potts to design the project. Completed in 1834 at a cost of roughly $150,000, the canal included a main raceway, 60 feet wide and six feet deep, and a stone and timber aqueduct spanning the Assunpink Creek. At its downstream terminus in Lamberton, the canal could generate a fall of 18 feet.
The Trenton Delaware Falls Company projected that at least 19 mills would soon be in operation along the banks of the new canal. By 1837, however, only seven mills above the Assunpink were running, while downstream from the aqueduct one pre-existing mill awaited hook-up and three others were still being built. Although other mills did start up,
In 1844-45, as the Trenton Delaware Falls Company was dissolved, New York industrialist Peter Cooper created the Trenton Water Power Company to acquire the earlier corporation’s assets. With his son, Edward, and son-in-law, Abram S. Hewitt, Cooper concurrently founded the Trenton Iron Company, passing control of the Water Power to this new manufacturing venture. Together the Trenton Iron Company and the Trenton Water Power became key components in the emerging Cooper & Hewitt iron and steel making empire. The Trenton Iron Company also assumed responsibility for the canal’s upkeep and for supplying water to other mills along its course. Through the Civil War era, the Water Power helped fuel the growth of the Trenton Iron Company, but the canal was frequently a frustration to its new owners. The ironworks sought to expand the waterway, but was opposed by other river users and Pennsylvania interests that did not want a larger dam across the Delaware. In 1852, this culminated in the “Stone-hackers War,” when ironworkers clashed on the wing dam with fishermen and laborers mining
As coal-fired steam replaced hydropower, the ironworks lost interest in the canal and by 1890 had ceased using water power altogether. The canal had to be maintained, however, since the city used the Water Power at its Calhoun Street water pumping station, and a dozen other mills were still drawing energy into the 1890s. In the second decade of the 20th century a segment of the canal was incorporated into Mahlon Stacy Park and renamed “Sanhican Creek.” During the 1930s the Water Power was re-routed to empty into the Delaware River at the water filtration plant and ceased to exist from this point downstream. The Water Power finally disappeared from view in the 1950s when Route 29 was placed along the portion of its alignment from Scudders Falls to Calhoun Street.
Where is the Water Power Now?
Not much survives of the Trenton Water Power today. The canal has been filled in and built over, and in many places obliterated. The mills along its course have long since been demolished. Route 29 lies atop much of the waterway’s alignment from Scudders Falls down to Waterfront Park. The Water Power lives now in the archival record and the realm of archaeology. The remains of the wing dam and
Industry at the Loop End of the Trenton Water Power
At the downstream end of the Trenton Water Power, beneath Waterfront Park and Riverview Executive Plaza, was a cluster of mills, one of which played an extraordinarily important role in American industry. When completed in 1834, the Water Power headrace looped down from a reservoir impounded by Federal Street, feeding a series of mill seats before emptying back into the Delaware River. In the late 1830s and 1840s, in the initial industrial development spurred by the Water Power, three textile mills came on line at the end of the looping raceway: the textile print works of the Union Manufacturing Company (established 1837); the cotton mills of the New England Manufacturing Company (founded in 1842; destroyed by fire in 1850); and the mill later known as the Saxony Woolen Mill (established as a cotton mill by 1846).
The industry for which this area became internationally famous, however; was
