...Summary...
The National Weather Service in Wilmington OH has confirmed a
weak tornado near Delaware Lake in Delaware County Ohio on
08/20/2016.

A weak tornado initially touched down just south of the Buckeye
Valley Middle School. The damage near the school was limited to
one tree with a limb down. The track continued north-northeast
into a residential area. In this residential area several 2 to 4
inch limbs were snapped and a few shallow-rooted trees were
uprooted. Roof damage was observed due to a fallen tree on Coover
Road and a barn had part of the roof cave in on its east side.

The tornado lifted until it crossed US-23 just west of Delaware
Dam. A small cluster of trees were twisted on the west side of the
highway.

The next location is Delaware State Park where the tornado was on
the ground for a few minutes. At Delaware State Park, a few
partially rotten large limbs were downed and numerous 2 to 3 inch
limbs were also downed. Also, several shallow rooted trees were
uprooted. A medium-sized dumpster near the marina was tipped and
moved about 20 feet. Three boats at the marina sustained minor
awning damage. A few 2 to 3 inch tree limbs around the marina were
snapped. Across the river from the marina, a snapped limb marked
the end of the tornado track.
