Moving to Celina: Pros, Cons & What to Know

Moving to Celina means moving to a real, distinctive small lake-resort town on Grand Lake St. Marys -- Ohio's largest inland lake and a genuine 19th-century engineering landmark -- anchored by a diversified manufacturing economy, with a real, honestly disclosed water-quality history worth knowing before you go.

A real, genuine 19th-century engineering landmark

Grand Lake St. Marys was dug by hand between 1837 and 1845 by roughly 1,700 German and Irish immigrant laborers to feed the Miami-Erie Canal. At its 1845 completion it was the largest artificially constructed lake in the world, and remains today the largest inland lake in Ohio by surface area (~13,500 acres) -- though genuinely shallow (average depth just 5-7 feet) (base record).

A real, honestly disclosed water-quality history -- and a genuine, ongoing recovery

This record discloses honestly, rather than omitting, that decades of agricultural nutrient runoff made Grand Lake St. Marys a real, EPA-cited "poster child" for harmful cyanobacteria blooms, most severely in summer 2010. The state of Ohio has since spent approximately $26 million on wetland restoration, with microcystin toxin levels in 2024 running significantly lower than the average of prior years -- a genuine, ongoing, not-yet-fully-complete recovery (base record).

A real, diversified manufacturing economy

Crown Equipment Corp. (a global forklift/material-handling manufacturer, ~1,050 local employees) and Honda-owned Celina Aluminum Precision Technology (~612 employees) anchor Celina's real, diversified local economy, alongside Reynolds & Reynolds and Mercer Health (base record).

A genuine two-county, small-town, car-dependent setting

Celina genuinely spans both Mercer and Auglaize counties and carries a genuine small-town, car-dependent character -- plan accordingly rather than expecting urban transit or walkability.
