Lake Pleasant was formed in 1812 from part of the Town of Johnstown before the formation of Hamilton County. Lake Pleasant was a "mother town" of the county and other towns were made, in whole or part, by removing parts of its territory: Morehouse (1835), Arietta (1836), part of Long Lake (1837), part of Hope (1847), part of Wells, (1858), and part of Indian Lake (1861).
In the past, the community of Lake Pleasant was also known as "Sageville" after Hezekiah Sage built a hotel and attempted to rename the community after himself.
