Umatilla National Wildlife Refuge, was established in 1969 for wildlife habitat lost to flooding caused by the construction of the John Day Lock and Dam.
The 25,347 acre refuge, located in the arid Columbia Basin of northeast Oregon and southeast Washington astride the Columbia River, includes open water, shallow marshes, backwater sloughs, croplands, islands, and shrub-steppe uplands.
Migrating waterfowl, bald eagle, colonial nesting birds, migratory songbirds, resident wildlife and rare and endangered species can be found on the refuge. It is strategically located within the Pacific Flyway to provide Arctic nesting geese and ducks a wintering site and a resting stopover.
