The Columbia River is the largest river in the Pacific Northwest region of North America. The river rises in the Rocky Mountains of British Columbia, Canada. It flows northwest and then south into the US state of Washington, then turns west to form most of the border between Washington and the state of Oregon before emptying into the Pacific Ocean. The river is 1,243 miles (2,000 km) long, and its largest tributary is the Snake River. Its drainage basin is roughly the size of France and extends into seven US states and a Canadian province. The fourth-largest river in the United States by volume, the Columbia has the greatest flow of any river entering the Pacific and the 36th greatest of any river in the world.

Wanapum Dam is a hydroelectric project located on the Columbia River downstream (south) from Vantage, Washington where Interstate 90 crosses the Columbia from Grant County into Kittitas County. It is owned by the Grant County Public Utility District. Its reservoir is named Lake Wanapum.
Priest Rapids Dam is a hydroelectric, concrete gravity dam; located on the Columbia River, between the Yakima Firing Range and the Hanford Nuclear Reservation, and bridges Yakima County and Grant County, in the U.S. state of Washington. The dam is 24 miles south of the town of Vantage, and 47 miles northwest of the city of Richland. It is located at mile marker 397.1 from the mouth of the Columbia. It is owned by the Grant County Public Utility District (PUD). Priest Rapids, for which the dam was named, are now submerged beneath the dam's reservoir.
The Cascades Rapids were an area of rapids along North America's Columbia River, between the U.S. states of Washington and Oregon. Through a stretch approximately 150 yards (140 m) wide, the river dropped about 40 feet (12 m) in 2 miles (3.2 km). These rapids or cascades, along with the many cascades along the Columbia River Gorge in this area of Oregon and Washington, gave rise to the name for the surrounding mountains: the Cascade Range.
The Pend Oreille River is a tributary of the Columbia River, approximately 130 miles (209 km) long, in northern Idaho and northeastern Washington in the United States, as well as southeastern British Columbia in Canada. In its passage through British Columbia its name is spelled Pend-d'Oreille River. It drains a scenic area of the Rocky Mountains along the U.S.-Canada border on the east side of the Columbia. The river is sometimes defined as the lower part of the Clark Fork, which rises in western Montana. The river drains an area of 66,800 square kilometres (25,792 sq mi), mostly through the Clark Fork and its tributaries in western Montana and including a portion of the Flathead River in southeastern British Columbia. The full drainage basin of the river and its tributaries accounts for 43% of the entire Columbia River Basin above the confluence with the Columbia. The total area of the Pend Oreille basin is just under 10% of the entire 258,000-square-mile (670,000 km2) Columbia Basin. Box Canyon Dam is currently underway on a multimillion-dollar project for a fish ladder.
Kettle Falls was an ancient and important salmon fishing site on the upper reaches of the Columbia River, in what is today the U.S. state of Washington, near the Canada–US border. The falls consisted of a series of rapids and cascades where the river passed through quartzite rocks deposited by prehistoric floods on a substrate of Columbia River basalt. The river dropped nearly 50 feet (15 m), and the sound of the falls could be heard for miles away. Kettle Falls was inundated in 1940, as the waters of the reservoir Lake Roosevelt rose behind Grand Coulee Dam, permanently flooding the site.
Celilo Falls was a tribal fishing area on the Columbia River, just east of the Cascade Mountains, on what is today the border between the U.S. states of Oregon and Washington. The name refers to a series of cascades and waterfalls on the river, as well as to the native settlements and trading villages that existed there in various configurations for 15,000 years. Celilo was the oldest continuously inhabited community on the North American continent until 1957, when the falls and nearby settlements were submerged by the construction of The Dalles Dam.
Ginkgo Petrified Forest State Park/Wanapum Recreational Area is a geologic preserve and public recreation area covering 7,124-acre (2,883 ha) on the western shoreline of the Columbia River's Wanapum Reservoir at Vantage, Washington. Petrified wood was discovered in the region in the early 1930s, which led to creation of the state park as a national historic preserve. Over 50 species are found petrified at the site, including ginkgo, sweetgum, redwood, Douglas fir, walnut, spruce, elm, maple, horse chestnut, cottonwood, magnolia, madrone, sassafras, yew, and witch hazel.
The Wanapum tribe of Native Americans formerly lived along the Columbia River from above Priest Rapids down to the mouth of the Snake River in what is now the US state of Washington. About 60 Wanapum still live near the present day site of Priest Rapids Dam. The name "Wanapum" is from the Sahaptin wánapam, meaning "river people", from wána, "river", and -pam, "people". Today they are enrolled in the federally recognized Confederated Tribes and Bands of the Yakama Nation.
Ross Dam is a 540-foot (160 m)-high, 1,300-foot (400 m)-long concrete thin arch dam across the Skagit River, forming Ross Lake. The dam is in Washington state, while Ross Lake extends 23 miles (37 km) north to British Columbia, Canada. Both dam and reservoir are located in Ross Lake National Recreation Area, is bordered on both sides by Stephen Mather Wilderness and combined with Lake Chelan National Recreation Area they make up North Cascades National Park Complex.
Steamboats operated on the Wenatchee Reach of the Columbia River from the late 1880s to 1915. The main base of operations was Wenatchee, Washington, located at the confluence of the Wenatchee and Columbia Rivers, 465 miles (748 km) from the mouth of the river. Operations were mainly between Wenatchee and Bridgeport. Rapids below Wenatchee and above Bridgeport prevented safe navigation.
State Route 243 (SR 243) is a state highway in Grant County, Washington. It travels north–south along the Columbia River for 28 miles (45 km), connecting SR 24 at the Vernita Bridge to SR 26 near Vantage. The highway travels through a predominantly rural and desert area, serving two hydroelectric dams and the communities of Desert Aire, Mattawa, and Beverly.
Wanapum Lake is a reservoir on the Columbia River in the U.S. state of Washington. It was created in 1963 with the construction of Wanapum Dam. It stretches from there upstream to the Rock Island Dam. The lake is named for the Wanapum people.
Priest Rapids Lake is a reservoir on the Columbia River in the U.S. state of Washington. It was created in 1959 with the construction of Priest Rapids Dam. The reservoir stretches from there upstream to the Wanapum Dam.
Beverly, Washington, United States, is a small unincorporated community along the banks of the Columbia River in central Washington state. The community, which consists of a few hundred residents, is a few miles downriver from Wanapum Dam and is nestled at the base of Sentinel Gap, a water gap in the Saddle Mountains that predates the Columbia River.
Sentinel Gap is a water gap formed by the Columbia River in the Saddle Mountains, near Mattawa in Washington state. The gap is "a water gap where erosion by the Columbia River was able to keep pace with folding, faulting and uplifting across the Saddle Mountain anticline". During Ice Age floods in which waters from the Channeled Scablands found passage to the Pacific Ocean here and at Wallula Gap, this opening was "repeatedly reamed out, which probably widened and steepened the walls of the gap". Strandlines from the floods can be seen on the basalt walls of the gap.
