Wood county is located in northwestern Ohio just south of the Toledo metro area and Lucas county and uses Bowling Green as the county seat. The county population on July 1, 1999, was 120,292, an increase of 7,023 over the 1990 census.
The county was organized in 1820 when the legislature created 14 counties from the lands purchased from the Chippewa, Delaware, Ottawa, Potawatomi, Seneca, Shawnee, and Wyandot tribes as a result of the Lower Maumee Treaty of 1817.
Wood county is named for Col. Eleazor Wood, a graduate of West Point who engineered Ft. Meigs in Perrysburg on the Maumee River in 1813. Once a part of the "Great Black Swamp", acreage was drained leaving rich, fertile soil as the basis for a successful agriculture industry in the county.
Natural features include parts of all four major tributaries of the Portage River.
