Brimson sits at the heart of this agricultural landscape in Grundy County, where the meandering courses of the Thompson River and Weldon River dictate the local topography. The map reveals a complex hydrographic network, including several oxbows and abandoned channels such as the Old Channel Thompson River and the Old Channel Weldon River, indicating a history of shifting watercourses. Numerous small tributaries, including Sugar Creek, Furnace Cr, and Raccoon Cr, drain into these larger river basins, creating a patchwork of fertile lowlands and rising hills.
