The Big and Little Darby Creeks long served people living along their banks and nearby land. In 1805, Samuel Dyer erected a grist mill that ground grain into flour for local farmers, powered by water diverted from Little Darby Creek through a hand-dug channel. During drought, a second hand-dug channel more than 100 yards long brought water from Big Darby Creek. The miller opened a sluice gate to send water through a millrace toward the mill, where it fell onto a large wheel and made it spin. This 1,740 pound stone is a remnant of that grist mill, which stood near the Little Darby Picnic Area and was recovered by the Baker Family during construction of the existing two bridges. In 2015, the Baker's donated the stone to Battelle Darby Creek Metro Park. Though many grist mills burned, Dyer's Mill did not; it was destroyed instead by the Great Flood of 1913, which caused an estimated 2 billion dollars in present-day damage to towns across Ohio and the Midwest.
