The City of Dayton, Kentucky, is along a bend of the Ohio River in Campbell County, Kentucky. The population was 5,338 at the 2010 census. It is less than 3 miles from downtown Cincinnati, Ohio. Dayton has a large sandbar just offshore. It had a popular beach for many years known as the "Manhattan Bathing Beach", until the US Army Corps of Engineers raised the level of the Ohio River. In 1779, the beach was involved in the Battle of Dayton, KY; the fight involved Simon Girty, Alexander McKee, Col, John Campbell, Col. David Rogers, and Capt. Robert Benham. Floods in 1884, 1913, and 1937 – the latter affecting 80 percent of the city and prompting residents to take shelter in the garages of the former Wadsworth Watch Case Co. A floodwall was finally completed in late 1981.       - wikipedia.org
