This collection contains records relating to the Chesapeake Duck Club and, more generally, the Bear River Migratory Bird Refuge that document the history of the club and enumerate the environmental conditions of the Utah wetlands from 1950 to the mid 1970s. Organizational and financial records include meeting minutes that indicate the steps the club took to manage this portion of the wetlands as well as correspondence that shows members’ positive experiences with the club. This collection also includes some ecological studies on Chesapeake wetlands. Together, they provide a rich account of the recreation and environmental issues on the northern wetlands of the Great Salt Lake.
