2017 Map of Defiance

About this map

O'Fallon and Lake St. Louis anchor the northern reaches of this Missouri landscape, where suburban expansion meets the deeply etched drainages of the Missouri River valley. The terrain is defined by a dense network of water bodies, most notably the extensive chain of numbered reservoirs such as August A Busch Lake Number 38 and August A Busch Lake Number 7. These lakes dominate the northeastern quadrant, signaling a transition from the structured residential blocks of the north to the more traditional rural patterns of the south.
