The states of Nebraska, Wyoming, and Colorado, and the US Department of the Interior have entered into a
Cooperative
Agreement (CA) partnership to address endangered species (whooping crane, piping plover,
least tern, pallid sturgeon) issues affecting the Platte River Basin. The initiative has two major
purposes:
