Rivers of Illinois Flyover Video collection
The National Park Service recorded aerial surveys of 11 Illinois rivers intended to support conservation and research by documenting river morphology, natural landscapes, and human development. VHS tapes were donated to the Illinois State Water Survey by the NPS in 2003 with the stipulation that they be preserved and made available. The tapes were digitized by the University Library in 2017. Details and links for individual videos are listed below.
