The Illinois River dictates the landscape of this Bureau and Putnam County region, carving a wide valley filled with complex backwaters and lakes. Depue Lake, Spring Lake, and Colemon Lake dominate the bottomlands, reflecting the historic hydrology of the river's floodplain. The settlement pattern shows a distinct split between river-level industry and upland farming. The village of Depue is situated along the northern bank, while Bureau Junction sits at the confluence where Bureau Cr meets the main channel.
