The Central Auxilary Operations Dams are arch-gravity dams that connect to the northern and southern areas of the Historic District of Metropolis.
Retaining the ocean surrounding Metropolis' city-proper, the dam connects with the Metropolis Hydro Plant and Water Treatment Facility.

Trivia[]

  • The C.A.O. Dam indicates that almost all of Metropolis' shoreline is not natural but the product of a much higher water level artificially brought upon by the dam, and the city sits within a massive reservoir, which is quite unusual.
  • The C.A.O. Dam is approximately 340 units tall. The reservoir water level is approximately 300 units higher than the sea level.
