The county originally contained an area of 163,340 acres or 255.25 square miles. When pioneer settlers came here to subdue the wilderness, much of the western portion of the county was partially covered with water and formed a part of what was then known as the “Black Swamp.” A small section of the eastern part of the county was known as the “Firelands,” which were donated by the state of Connecticut to persons who were made destitute by the burning of their property by the English during the Revolutionary War.
Large portions of the county’s marsh land have produced heavy crops or wheat, corn, soy beans, corn, potatoes, and onions. The eastern portion is better adapted to grow fruit, especially peaches and grapes, though the west end has many fine orchards. Limestone is found in abundance throughout the county. Limestone is found in abundance and mines are found in Marblehead, Genoa, Rocky Ridge, Limestone, Williston, and Clay Center. Gypsum is found in large quantities near the town of Gypsum. Fishing is a prominent industry and among the foremost in the state.

COUNTY BOUNDARIES
The Ottawa County mainland borders the southern shores of Lake Erie. The eastern part forms a peninsula like a thumb and a finger and projects into Lake Erie to the north and Sandusky Bay to the south.
Several Islands in Lake Erie and in Sandusky Bay are also included within the Ottawa County boundaries. This is in addition to a land portage, expanding from the near the mouth of the Portage River to approximately where the Sandusky River joins the bay; it served as a shortened route of the Sandusky Scioto Trail that led from the Detroit region to the Ohio River.
Additional land boundaries include Lucas County on the north, Wood County on the west, and Sandusky County on the south.
