The Crane Trust is a non-profit organization dedicated to the protection and maintenance of critical habitat for whooping cranes, sandhill cranes and other migratory birds along the Big Bend Region of the Platte River Valley through sound science, habitat management, community outreach and education. In addition, the Crane Trust operates the Nature & Visitor Center to help fulfill its mission by providing a more active gateway and resource for community outreach and education.The Crane Trust, Inc. was formed in 1978 as part of a court-approved settlement of a controversy over the construction of Grayrocks Dam on a tributary of the Platte River in Wyoming. The state of Nebraska and the National Wildlife Federation objected to the project, claiming it would jeopardize irrigation and wildlife downstream in Nebraska. The settlement satisfied requirements of the Endangered Species Act and allowed the Missouri Basin Power Project, owners of Grayrocks, to complete construction. The Crane Trust was funded by a payment from the Missouri Basin Power Project, and income from the endowment is used to finance land acquisition. The Trust is administered by three trustees who are appointed by the three participants in the settlement.
