Heavy thunderstorm rains fell on the northeastern corner of Knox County during the afternoon and early evening hours of July 10th. A spotter near the intersection of State Route 3 and College Hill Road (just south of the Ashland County line) measured a storm total of 7.5 inches. Up to 7 inches of rain was reported in the Danville area with 5.5 inches of this total falling between 3 and 5 p.m. Both the Mohican River and Jelloway Creek quickly went into flood and caused considerable damage. Runoff from the heavy rains caused the Mohican River to rise more than a foot per hour through the evening hours. Campgrounds along Wally Road were especially hard hit by flooding from the Mohican River. Dozens of mobile homes and campers were damaged or destroyed. Hundreds of campers from several campgrounds had to be evacuated from the rapidly rising waters. Several landslides along Wally Road hampered the evacuations which continued through the evening hours. Homes near Greer were also affected by flooding from the Mohican River, and State Route 514 had to closed southwest of the town. A lot of flooding also occurred in and near Jelloway after Jelloway Creek went into flood. Four families had to be evacuated from homes along State Route 205 south of Jelloway. Other evacuations occurred along Howard-Danville Road southwest of Danville. Shadley Valley Creek also went into flood prompting several evacuations along Shadley Valley Road. Bridges were washed out on College Hill Road and Pealer Mill Road. At least five roads were washed out in the northeastern corner of the county. Over two dozen roads had to be closed because of flooding. Dozens of homes in the county sustained damage from basement or nuisance flooding.

Flash Flood, Ashland

When: July 10, 4:00 PM EST to 9:30 PM EST
Where: Ashland County, South Portion
Property damage: $5.2 million
Crop damage: $750,000
Reported by: EMERGENCY MANAGER
Coordinates: 40.846, -82.271 (the zone’s center; the record gives no point)

Heavy thunderstorm rains fell on the southern portion of Ashland County during the afternoon and early evening hours of July 10th. Rainfall rates approached 3 inches per hour at times and a spotter near the intersection of State Route 3 and College Hill Road, just south of the Ashland County line, measured a storm total of 7.5 inches. Cooperative observers at the Mohicanville Dam measured 2.8 inches of rain between 3 and 4 p.m. and a storm total of 3.41 inches. Other reports from the county included: 3.26 inches in Loudonville, 2.89 inches at Pleasant Hill Dam and 2.10 inches in the City of Ashland. Runoff from the heavy rains caused the Mohican River to rise very quickly. A four foot wall of water reportedly moved down the river forcing several people in canoes to climb into trees. Firefighters later rescued eight people from the river or trees. The river continued to rise more than a foot per hour through the evening hours. Up to 700 campers had to be evacuated from Mohican State Park, many by boat. Several campgrounds on Wally Road south of Loudonville also had to be evacuated because of flooding. These evacuations continued through 10 p.m. and were hampered by several mudslides along Wally Road. A woman had to be rescued from her home on Pleasant Hill Road. Dozens of campers and mobile homes were damaged in the State Park and campgrounds. Extensive flooding also occurred along Pine Run south and west of Loudonville. Four barns along the run were washed away and a bridge on State Route 3 was heavily damaged. An historic mill along Pine Run sustained over $100,000 in damage. County Roads 3275, 1027 and 3175 (Wally Road) were washed out in several locations. At least seven Hanover Township roads were also washed out. Total damage to roads and bridges in the county approached $1 million. Flooding was reported as far north as the City of Ashland where several streets were flooded. Over two dozen roads in the county had to be closed because of flooding including State Route 60 south of Hayesville, and State Routes 3, 39 and 97 near Loudonville. Hundreds of homes and mobile homes sustained damage, mainly from basement flooding. Crop losses in the county are also expected to be substantial as standing water delayed the wheat crop harvest.

Flash Flood, Richland

When: July 10, 4:09 PM EST to 9:30 PM EST
Where: Richland County, South Portion
Property damage: $600,000
Crop damage: $250,000
Reported by: EMERGENCY MANAGER
Coordinates: 40.775, -82.536 (the zone’s center; the record gives no point)

Heavy thunderstorm rains fell on the southern portion of Richland County during the late afternoon and early evening hours of July 10th. Rainfall rates with the stronger storms approached three inches per hour. A spotter east of Butler measured 5 inches of rain between 3 and 5 p.m. and a storm total of 7 inches. An automated gage near Belleville measured a storm total of 3.09 inches. Runoff from the rain caused extensive flooding along the Clear Fork of the Mohican River. The river left its banks and damaged a bridge on State Route 95 just northeast of Butler. A culvert neaby was also washed out. Street flooding was reporting in Butler and also in Mansfield. Many homes sustained damage, mainly from basement flooding. Several roads had to be closed because of flooding. Crop losses are also expected as standing water delayed the wheat crop harvest.

Flash Flood, Holmes

When: July 10, 5:30 PM EST to 9:30 PM EST
Where: Holmes County, West Portion
Property damage: $1.1 million
Crop damage: $250,000
Reported by: EMERGENCY MANAGER
Coordinates: 40.561, -81.929 (the zone’s center; the record gives no point)

Heavy thunderstorm rains fell on the northwestern corner of Holmes County during the late afternoon and early evening hours of July 10th. Rainfall rates with these storms were in excess of three inches per hour. Automated gages measured storm totals of 6.52 inches in Nashville and 3.96 inches at Stillwell. Significant flooding occurred in the northwestern portion of the county along the Mohican River. Flooding occurred as much as 300 feet away from the river, and campgrounds along Wally Road sustained significant damage. Hundreds of campers had to be evacuated, many by boat. The evacuations continued through 10 p.m. and were hampered by mudslides along Wally Road. State Route 520 was flooded near Glenmont by Black Creek. A couple homes in the town had flood waters 1 to 3 feet deep on the ground floor. Several roads were washed out and many others had to be closed because of flooding. State Route 39 and County Road 22 were both impassable west of Nashville. Dozens of campers and mobile homes were damaged by the flooding. Many other homes sustained damages from basement flooding. Crop losses are also expected to significant as standing water damaged many fields.
