Cheyenne, WY – A study by the National Academy of Sciences is validating the finding there is critical habitat for endangered and threatened species on the Platte River. The U-S Fish and Wildlife Service and Bureau of Reclamation came out with those same findings months ago, but the Academy of Sciences commissioned a study to verify their work. Committee Chairman Will Graf recognizes that saying there is critical habitat on the river in Nebraska will have an impact in Wyoming. He says most of those who testified before his committee made sure the committee was aware that water use patterns may have to change upstream. Because the study is finished, public comment on the draft plan to manage the Platte River is now underway.
