Mercer County comprises the Celina, Ohio Micropolitan Statistical Area

History

Mercer County was created in 1820 from land that had been attached to Darke and Shelby counties. Land south of the Greenville Treaty Line was still part of Darke County. An act establishing and fully organizing Mercer County took place on January 2, 1824. In 1837 Van Wert County was detached and the county line established is the current northern border of Mercer County. In 1839 Celina was established as the seat of Mercer County; St. Marys was the previous seat. In 1848 the area south of the Greenville Treaty Line to the current southern county line, was attached. When Auglaize County was formed, Mercer County's eastern border was moved 6 miles (9.7 km) west with the exception of the area south of the Greenville Treaty Line. This created the sharp point at Mercer County's southeast corner and was the last county line modification.

In the mid to late 1800s, Mercer County became home to many German immigrant farming families. Many of these German Americans had immigrated from northwestern Germany.

Geography

According to the U.S. Census Bureau, the county has a total area of 473 square miles (1,230 km2), of which 462 square miles (1,200 km2) is land and 11 square miles (28 km2) (2.3%) is water. [5] The entire county has an elevation difference of less than 300 feet. The highest point is on the southern county line at 1071 feet above sea level. This is in proximity to the head waters for the Wabash River. The lowest point in the county is 780 feet above sea level. This point is located on the northern county line where the St. Marys River crosses over.

Drainage basins

Mercer County has two rivers running through it; the Wabash and the St. Marys. The Wabash watershed is part of the Gulf of Mexico's watershed. The St. Marys watershed is part of Lake Erie's watershed. Creeks between these two watersheds are within a mile of each other at some places in Mercer County. The summit line that divides the drainage basins is known as the St. Lawrence Continental Divide

Beaver Creek

Beaver Creek is the longest and largest creek in Mercer County. It stretches 19.7 miles and has two sections. The first section begins in southern farmland in the county and flows through the town of Montezuma, Ohio and into Grand Lake St. Marys. The other section of the creek begins as a spillway and empties into the Wabash River. Beaver Creek was originally one piece, but was split into two sections after the construction of Grand Lake. The creeks' spillway, and last section, has been the subject of controversy and multimillion-dollar lawsuits. Farmers along Beaver Creek claim their land floods because of the spillway that was put up in 1997, replacing the previous spillway, built in 1913. [6]

Government

Mercer County has a 3-member Board of County Commissioners that oversee the various County departments, similar to all but 2 of the 88 Ohio counties. Mercer County's elected commissioners are: Jerry Laffin, Rick Muhlenkamp, and David Buschur. [7]

Politics

Prior to 1940, Mercer County was primarily Democratic, only voting Republican once from 1856 to 1936 for Ohioan Warren G. Harding in 1920. From 1940 to 1968, the county was a Republican-leaning swing county, voting for Republican candidates four times and Democratic candidates three times, although John F. Kennedy came within 5 votes of carrying it in 1960. The 1972 election began the county's streak of being a Republican stronghold presidentially, with the party's margins of victory increasing to well over 50 percent in recent elections.
