Thompson anchors the southeastern corner of this Winnebago County landscape, where the agricultural grid of northern Iowa meets the headwaters of the Blue Earth River system. The terrain is defined by a complex network of wetlands and small waterways, including the meandering Middle Br Blue Earth River and Little Buffalo Cr. These natural drainages are supplemented by man-made infrastructure like Drainage Ditch Number 64, reflecting the region's long-standing commitment to land reclamation for farming.
