Uhlersville was once a bustling town of 200 people built around a lock on the Delaware Canal, where Peter Uhler, a 17-year-old local farmer, seized the opportunity created in the late 1820s when the canal and the first two locks south of Easton cut through his land and developed houses and businesses on both sides. Praised in 1851 for showing unusual taste, convenience, and comfort for a country village, the town grew and prospered until the late 1860s, when canal trade slowed, whiskey was heavily taxed, most of the trees had been cut down and reduced the lumber supply for the paper mill and sawmill, and quality limestone was no longer available. Peter Uhler died a rich and influential man in 1877, but his son did not continue that good fortune, and the 27-acre property and remaining mill were sold to a paper manufacturing company in 1890. The mill was never successful, changed owners and uses many times, and the town's fate was sealed in 1929 when a spark from a welder's torch ignited a fire that destroyed the mill during renovation. Some structures were later destroyed during construction of the trolley line and Route 611, others disappeared for unknown reasons, and only the canal lock, the locktender's house, a few building foundations, a water tower, and the ruins of Peter Uhler's dam remain.
