Yorkville Village

• Yorkville sits directly on the Ohio River in Jefferson County and was originally built up as a coal-mining town.
• The village's population has fallen by roughly half since its actual 1930 peak of 1,963 residents (968 at the 2020 census), per Census figures.
• Yorkville operated its own two wells until October 2021, when EPA records show it deactivated them and completed its shift to buying finished water wholesale from neighboring Tiltonsville.
