The Detroit Zoological Society has plans for a third site, the Great Lakes Center for Nature, which will be mainly an aquarium. The proposed facility will cost $15 Million.
Quote from Detroit Zoo website: "The Great Lakes Center for Nature will be home to a number of Great Lakes fish, including lake sturgeon – and will focus on conservation efforts for these and other endangered species. It will include habitats for native amphibians, reptiles, small mammals, shorebirds, and birds of prey – many of which will have been rescued and are non-releasable – and will also feature a native butterfly garden."
