How Chilo began

Chilo, a small Ohio River village in Franklin Township, was platted in 1816 under the name Mechanicsburgh, with a post office following in 1819. The Ohio legislature changed its name to Chilo in 1820. The village became a boat-building center in the 1830s, briefly drawing hundreds of workers and supporting more than thirty houses and two stores. For much of the 20th century it was home to Lock 34 on the Ohio River, until the nearby Meldahl Dam replaced the lock system in the 1960s; the old lock structure now houses the Ohio River Museum, run by the Clermont County park district.

Platted 1816.

Where the name comes from

The village was originally platted and known as Mechanicsburgh. The Ohio Legislature changed its name to Chilo by act in 1820; no source consulted here explains the meaning or origin of the replacement name itself.

Before the town

No mound, earthwork or documented historic-era Native village, encounter or battle specific to the village site of Chilo was found in the sources searched, but the 1880 county history records prehistoric "mounds of observation" -- conical earthen mounds three to fifteen feet high, generally understood by the 19th-century historian to have once carried beacon fires -- on the farm of a Dr. Wood near Chilo, among the county's clearest examples of this type, along with similar mounds on the farm of John Shaw near New Richmond and on land in Pierce Township. No source ties these mounds to a named historic nation. The surrounding area's history also includes Manning's Station, built about 1795 in the same township as a defensive refuge, and the abandoned 1795 settlement attempt at nearby Neville.

Stories

A lockhouse becomes a museum

For nearly forty years the operations building at Ohio River Lock and Dam No. 34 stood at the river's edge in Chilo, a working part of the wicket-dam system that let steamboats and barges pass through the shallows here. The U.S. Army Corps of Engineers shut the lock down in 1964, once the newer, more capable Captain Anthony Meldahl Dam opened a few miles downstream and made Lock 34 obsolete. The building then sat empty for decades, a quiet leftover of the river-transportation era that had briefly, in the 1830s, turned this same small village into a boat-building boomtown of its own. In 2005 the Clermont County Park District renovated the old operations building into the Chilo Lock 34 River Museum, opening its exhibits on steamboats, historic floods, and the people who lived and worked on the Ohio River to the public on the same ground where the lock once raised and lowered the river's traffic.
