The center of a vibrant downtown and a commercial shipping hub, the Milwaukee Harbor teems with underwater activity in pockets of habitat full of aquatic life. But look on any map and the harbor is just a blue-black void. The map on this page fills in that gap and invites you to explore the complexity of this remarkable urban ecosystem.
