The Hanford Reach National Monument is a national monument in the U.S. state of Washington. It was created in 2000, mostly from the former security buffer surrounding the Hanford Nuclear Reservation. The area has been untouched by development or agriculture since 1943. For this reason, it is considered an involuntary park.
The monument is named after the Hanford Reach, the last non-tidal, free-flowing section of the Columbia River in the United States, and is one of eight national monuments administered by the U. S. Fish and Wildlife Service; part of the monument within the Hanford Site is also managed by the Department of Energy. President Bill Clinton established the monument by presidential decree in 2000. In May 2017, the Interior Department announced that Hanford Reach was one of 27 national monuments under review for possible rescinding of their designation. [2]
Ancestors of the Wanapum People, Yakama Nation, Confederated Tribes of the Colville, Confederated Tribes of the Umatilla Reservation and the Nez Perce used the land for hunting and resource collecting.[ citation needed ]
Geographically, the area is part of the Columbia River Plateau, formed by basalt lava flows and water erosion. The shrub-steppe landscape is harsh and dry, receiving between 5 and 10 inches (250 mm) of rain per year. The sagebrush-bitterbrush-bunchgrass lands are home to a wide variety of plants and animals, and the Hanford Reach provides one of the northwest's best salmon spawning grounds. Forty-eight rare, threatened, or endangered animal species have found refuge on the monument, as well as several insect species found nowhere else in the world. [3]
There are two main habitats in the Hanford Reach National Monument: desert and river.
Islands, riffles, gravel bars, oxbow ponds and backwater sloughs provide support to forty-three species of fish. Large numbers of fall Chinook salmon spawn in the Hanford reach. Federally threatened species such as the Upper Columbia River Spring Chinook, the Middle Columbia River Steelhead and the Upper Columbia River Steelhead use the reach for migration purposes. [4]
The refuge is famous for the elk located on the Arid Lands Ecology Area. Herd numbers vary by time of year with 150 seen during the spring/summer and 350 to 375 during the fall. The elk population reaches its peak in the winter with an average of 670. Archaeologists believed the elk had been in the region for the last 10,000 years. During the mid-19th century, first hand accounts mentioned the disappearance of the species. Rocky Mountain elk were reintroduced into the region during the 1930s, [5] as well as a natural recolonization event from the nearby cascade mountains during the difficult 1978 winter.
The dry, desert region is home to forty-two mammal species. Mice are the most abundant and include the deer mouse, western harvest mouse, northern grasshopper mouse. Mammals that inhabit this refuge include coyotes, skunks, beavers, mule deer, bobcats, river otters, minks, cougars and badgers.
Hanford Reach is home to nine nuclear reactors of which B Reactor is the most famous; constructed in 13 months during World War II, it was the world's first full scale reactor. Plutonium from the reactor was used in physics package for the first nuclear detonation at the Alamogordo Bombing and Gunnery Range in New Mexico (July 16, 1945) and in the Fat Man atomic bomb dropped on Nagasaki, Japan (August 9, 1945). [6]
The reactor's significance has led to many distinctions including a place on the National Historic Mechanical Engineering Landmark, National Register of Historic Places, Nuclear Historic Landmark, National Civil Engineering Landmark and National Historic Landmark.

The United States Fish and Wildlife Service is a U.S. federal government agency within the U.S. Department of the Interior which oversees the management of fish, wildlife, and natural habitats in the United States. The mission of the agency is "working with others to conserve, protect, and enhance fish, wildlife, plants and their habitats for the continuing benefit of the American people."
The National Wildlife Refuge System (NWRS) is a system of protected areas of the United States managed by the United States Fish and Wildlife Service (FWS), an agency within the Department of the Interior. The National Wildlife Refuge System is the system of public lands and waters set aside to conserve America's fish, wildlife, and plants. Since President Theodore Roosevelt designated Florida's Pelican Island National Wildlife Refuge as the first wildlife refuge in 1903, the system has grown to over 568 national wildlife refuges and 38 wetland management districts encompassing about 859,000,000 acres (3,476,200 km2).
The Bosque del Apache National Wildlife Refuge is a National Wildlife Refuge located in southern New Mexico. It was founded in 1939 and is administered by the U.S. Fish and Wildlife Service. It is a favorite spot to observe sandhill cranes, which spend the fall and winter in the area. The reserve is open year-round and provides safe harbor for its varied wildlife. Visitors to the refuge also enjoy partaking in activities such as hiking, cycling, driving tours on the 12-mile scenic auto route, and participating in educational programs offered on site.
The Kodiak National Wildlife Refuge is a United States National Wildlife Refuge in the Kodiak Archipelago in southwestern Alaska, United States.
The B Reactor at the Hanford Site, near Richland, Washington, was the first large-scale nuclear reactor ever built. The project was a key part of the Manhattan Project, the United States nuclear weapons development program during World War II. Its purpose was to convert natural uranium metal into plutonium-239 by neutron activation, as plutonium is simpler to chemically separate from spent fuel assemblies, for use in nuclear weapons, than it is to isotopically enrich uranium into weapon-grade material. The B reactor was fueled with metallic natural uranium, graphite moderated, and water-cooled. It has been designated a U.S. National Historic Landmark since August 19, 2008 and in July 2011 the National Park Service recommended that the B Reactor be included in the Manhattan Project National Historical Park commemorating the Manhattan Project. Visitors can take a tour of the reactor by advance reservation.
