At the end of the last Ice Age, 18,000 to 15,000 years ago, an ice dam in
northern Idaho created glacial Lake Missoula stretching 3,000 square miles
around Missoula, Montana. The dam burst and released flood waters across
Washington, down the Columbia River into Oregon before reaching the Pacific
ocean. The Ice Age Floods forever changed the lives and landscape of the
Pacific Northwest.

It's quiet and peaceful. In winter, nearly silent. In summer, listen for
insect music. The sky is big, the space vast. It invites you to explore. Bring
along your curiosity.

Surprising to most people outside the Northwest, the landscape of eastern
Washington is that of a desert. In its natural state, almost all of Columbia
National Wildlife Refuge would be considered desert, with the exception of the
naturally ephemeral Crab Creek. However, rather than a desert of cacti and
mesquite, eastern Washington's desert is that of shrub-steppe, with sagebrush
and bunchgrasses.

Like most of eastern Washington, much of the refuge is no longer in its
natural state. The construction of the Columbia Basin Project forever altered
the landscape, bringing water to the desert. Seepage from irrigation
structures and reservoirs created wetlands, riparian areas and small lakes on
the once-dry landscape. The seasonal Crab Creek has become perennial, even
providing habitat for endangered salmonids.

The creation of lakes and wetlands would not have happened without the
geologic upheavals of ages past. During the last Ice Age, sheets of ice
spreading down from Canada blocked rivers with dams of ice. Occasionally—or
perhaps hundreds of times—the dams failed, sending floodwaters greater than
the flow of all the world's rivers combined tearing across eastern
Washington's lava fields, gouging coulees, redistributing boulders, depositing
massive sand and gravel bars, scraping the land bare in some areas and leaving
behind rich soils elsewhere. Nowhere are these depressions and geologic nooks
more prevalent than on the refuge. In turn, this torn-up land—the Drumheller
Channeled Scablands, National Natural Landmark—formed just the right
topography to capture the new hydrology of the Columbia Basin Project,
creating wetlands in the desert.

Water in the desert means an abundance of life. In its original state, the
land supported coyotes, rattlesnakes, mule deer, horned larks, sage sparrows
and other creatures of the shrub-steppe, although densities were limited.
Water has changed all this, however. Many of the naturally occurring species
can be found at higher densities (e.g., mule deer). Other species are
newcomers, totally dependent on the artificial water; black-necked stilts and
American avocets are some of the flashier ones. Still more species that may
have made an occasional appearance can now be found in great numbers—Canada
geese, northern pintails, and the refuge's most famous visitors, lesser
Sandhill cranes. It was because of this newly created wildlife oasis, and the
need to provide suitable mitigation for the Columbia Basin Project, that the
refuge was created in 1944 "for migratory birds and other wildlife."

Another thing that water brings is recreational use. Without water, there
wouldn't be any fishing,waterfowl hunting, or boating. It's likely that there
would be less hiking, biking, horseback riding, or sightseeing; visitors are
drawn to water and the vegetation and wildlife it fosters. Water brings the
Sandhill cranes, the migrating songbirds and the waterfowl that people come to
see, learn about and find for their "life-lists." It provides the serenity and
the visual contrasts that draw the eye, and then the feet, of visitors.
Without water, recreation and visitor use would be dramatically less on
Columbia National Wildlife Refuge.

The Columbia Basin Project did more than create the need for, and provide
water to, the refuge. It also created irrigated farmland, which secondarily
provided a food source for many of the refuge's species. For example, the
great concentration of Sandhill cranes found on the refuge in the spring is a
recent event, beginning in earnest in the late 1980s. Before then, the cranes
likely passed through the area on their way to breeding grounds in south-
central Alaska without more than a brief stop. Now, leftover grain in farmers'
fields has become an important food source for migrating cranes, concentrating
them by the thousands for several weeks in late winter and early spring. Other
wildlife, most notably migrating waterfowl, mule deer and numerous rodent
species, also take advantage of the harvest. While much of the habitat found
on the refuge (most of the lakes, wetlands, springs and perennial streams) is
the result of an artificial infusion of water, it is important to note that
the habitats themselves are not artificial. Natural wetlands and shallow lakes
can be found within the Columbia Basin, and those on the refuge function the
same way as naturally occurring ones found elsewhere within the area. So,
while many of the habitat types on the refuge would naturally be found in far
smaller acreages, if at all without seepage water from the Columbia Basin
Project, the only non-natural habitat types present are farm fields and moist
soil management areas.
