How Warren County's Borders Changed

Warren County was created in 1803 by Ohio's first government. Its original borders were set along rivers and specific land divisions. At first, it included land that is now part of Clinton County.

The state government had trouble with Clinton County's size. The Ohio Constitution says every county must be at least 400 square miles. So, Clinton County's borders were changed many times. In 1815, a strip of land was taken from Warren County to give to Clinton County. To make up for this, a part of Butler County was added to Warren County. This part is where Carlisle is now.

Rivers and Lakes

The two main rivers in Warren County are the Great Miami River and the Little Miami River. The Great Miami River flows through the northwest part of the county. The Little Miami River winds its way across the county from north to south.

There is also one large lake called the Caesars Creek Reservoir. It was made by a dam on Caesars Creek. This lake is in the northeast part of the county.
