The beaver drop was a 1948 Idaho Department of Fish and Game program to relocate beavers from Northwestern Idaho to the Chamberlain Basin in Central Idaho. The program involved moving 76 beavers by airplane and parachuting them down to the ground. The program was started to address complaints about property damage from residents. Parachuting beavers proved to be more cost-effective and it also decreased beaver mortality rates more than alternative methods of relocation.
