The story of Haddam

The day the webbing mill went over the falls

Higganum grew up where three brooks meet to form the Higganum River. An 1819 survey found the water falling thirty-one feet in twenty-five rods near its mouth, and guessed a village would rise there. It did. By 1884 the Higganum Manufacturing Company made over 400 kinds and sizes of plows and sold two-thirds of its goods abroad, and D. and H. Scovil made a planter's hoe for the cotton states. Then came October 4, 1869. After three days of rain a reservoir upstream gave way. The flood tore down Candlewood Hill Brook, rolled boulders into the village center, and lifted the two-story webbing mill off its foundation. It went over the falls, tore the corner off the cotton mill, and broke to pieces at the bottom.78910

Granite, shad and cordwood

For two hundred years the river paid Haddam's way. Deacon Ezra Brainerd opened a granite quarry on Haddam Neck in 1762, and another opened on the west side in 1794. By 1836 about 150 men worked the quarries, and the stone went by water as far south as Savannah and New Orleans. Every spring the shad ran, and in 1819 Haddam had 17 places to catch them. The biggest single haul anyone then remembered came at the Pier in Haddam in 1802, about 2,300 fish in one draught of the net. In 1807 the town shipped three thousand cords of wood, two thousand of them from Higganum Landing, where a sloop had been launched as early as 1754.113122

A tailor's rock and other Haddam names

Old Haddam names hold old stories. The settlers called the island in the river Thirty Mile Island, thinking it lay thirty miles from the mouth of the Connecticut; in 1819 it held 18 acres. A 1906 history says Higganum comes from a Native name meaning the fishing place, and Ponset is what's left of Cockaponset. Ponsett people were proud of that name, and one of them wrote that they had little patience with the phrase West Haddam. Half a mile above Higganum is Shopboard Rock, a bare slope about 60 feet high. Tradition says a tailor once cut a suit of clothes on it for a customer he met there, and the name was already on the town records by 1713.13141516
