The town of Ottosen sits in the southwestern corner of this agricultural survey, marking the transition from Humboldt County into Kossuth County. The landscape is defined by an extensive network of water management features, including Drainage Ditch Number 79 and Drainage Ditch Number 8, which support the intensive farming grid of north-central Iowa. These engineered waterways feed into natural systems like Lotts Creek and Trulner Cr, illustrating how the prairie wetlands were systematically drained to create productive cropland.
