Diamond Island (Kentucky)

Diamond Island is an unincorporated community and former island located in Henderson County, Kentucky, United States. The area now sits on the mainland due to shifts in the Ohio River. Historically, it was a significant landmark and sometimes referred to as simply "Diamond."

The island's primary industry was agriculture. Its fertile soil, a result of frequent flooding, made it ideal for growing crops such as corn and soybeans. Early settlers farmed the land extensively.

Over time, the Ohio River's course changed. The river gradually eroded land on one side of the island and deposited sediment on the other, eventually connecting Diamond Island to the Kentucky mainland. This process effectively transformed the island into a peninsula and then integrated it fully into the surrounding landscape.

Despite no longer being an island, the name "Diamond Island" persists and identifies the community that resides in the area. The location is primarily rural with a small population and retains a strong connection to its agricultural heritage. The area is also known for hunting and fishing opportunities.

The precise historical timeline of the island's formation, erosion, and eventual connection to the mainland is not meticulously documented, but anecdotal evidence and historical maps support the narrative of the river's influence on the land's transformation.
