The weather is a chronic topic, and one which is fairly safe to discuss without an argument. One difference between now and 150 years ago is that there were fewer floods or extreme high-water periods. When the countryside was wooded and there was no farm tiling or ditching, water ran off the land more slowly. Thus, the streams ran at about the same level most of the year as the water drained slowly from the woods, and they could better support water-powered mills.
On April 10, 1860, there was a heavy rainstorm (called a freshet in those days) which caused major flooding in central and northern Ohio. It was said that almost every mill dam on the Huron River was damaged. This must have also applied to the Vermilion River, as witnessed by a Clarksfield incident which created one of the many flood stories for Clarksfield Hollow.
Two young men, Augustus Morris and Orlando Starr, tried to traverse the road to the bridge (I presume the main bridge site on Ohio 60 North) with horses and a wagon. The road was covered with water and the team and wagon were soon washed into the river.
Morris and Starr managed to grab onto a small tree. A rope was quickly floated out to them from the bridge and Morris began pulling himself to safety. He was underwater much of the time, but did reach dry land. It was thought too dangerous for Starr to try this same method as he was already chilled and not as alert. One Mr. Livermore went out in a small boat and reached the tree, but decided the boat was too small for both of them and Starr was nearly exhausted.
