Located within the Till Plains ecoregion, sections of the Auglaize River and Saint Mary’s River, including the eastern 1/4 of Grand Lake, are located within Auglaize County. Most of the county is in the Lake Erie Watershed. See pp. 11-12 in Ohio Coastal Atlas: Chapter 2 for a detailed watershed map. Water from Auglaize Co provides headwaters to St Marys River, Auglaize River, Scioto River, and the Great Miami River. The St Marys and Auglaize are both tributaries of the Maumee. Scioto water flows east, Great Miami water flows south. Auglaize Co also contains portions of Grand Lake St Marys and Lake Loramie.
