"Turnbull National Wildlife Reserve encompasses approximately 16,000 acres of the Channeled Scablands. The powerful forces of volcanism, glaciation and the largest flood in geological history have combined to forge a distinct environment. The combination of basalt outcrops, channeled canyons and ponderosa pine forests infused in a diverse landscape of over 130 marshes, wetlands and lakes, create an environment of aesthetic beauty as well as high quality wildlife habitat. The 3,036 acres of wetlands on Turnbull NWR represent some of the last quality breeding habitat available in eastern Washington for waterfowl, which have experienced tremendous population declines across North America due to loss and degradation of breeding, migration and wintering habitat."
