The Blanchard River and its complex network of drainage ditches, including Mack Ditch and Lammer Ditch, define the agricultural landscape of this Putnam County region. The village of Ottawa serves as a central hub, anchored by the Putnam County Courthouse, while the neighboring settlement of Glandorf maintains its own distinct identity along Western Avenue. The local reliance on water management and regional infrastructure is evident in the large Ottawa Upground Reservoir and the presence of small rural airfields like Ruhe's Airport and Agner Airport. Genealogists will find several burial grounds across the township, from the central Saints Peter and Paul Cem to the more outlying McConnel Cem and Crow Cem, providing clear spatial context for families in New Cleveland, Miller City, and Elm Center.
