Columbia Basin Initiative
The Columbia Basin Initiative is a 2023 agreement between the U.S. government, four sovereign Native American Tribes (Nez Perce, Yakama, Warm Springs and Umatilla) and the U.S. states of Washington and Oregon to provide over $1 billion in funds for salmon restoration and clean energy production. The agreement comes after over twenty years of litigation with the U.S. government for violating the Endangered Species Act.
