The confluence of the Iowa River and the Mississippi River creates a complex network of waterways, chutes, and islands along the border of Iowa and Illinois. In the early 21st century, this landscape remains dominated by the shifting hydrology of the river system, featuring prominent landforms like Otter Island and Cuba Island. The settlement of New Boston sits on the Illinois bank overlooking Boston Bay, while across the water in Iowa, Toolesboro is situated near the river bluffs.
