Hobb's River

Hobb's River is a fictional body of water featured in comic books published by DC Comics. It is associated with the Superman line of comic titles. Hobb's River is a river that runs through the city of Metropolis including the Hobb's Bay neighborhood, as well as adjacent Kirby County. Beneath the river is a cave system that leads into Mount Curtiss, which is where Project Cadmus is located. During a time when Superman was believed to be dead, Lex Luthor II explored the underground tunnels that ran beneath Centennial Park. He accidentally tripped a series of explosives set by Cadmus agents as a security protocol, and water from the above Hobb's River came flooding in.
