The Columbia River is the largest river flowing into the Pacific Ocean from North America. Interestingly, this gigantic river holds about a third of the potential hydropower of the United States. Actually, in the river behind Grand Coulee Dam, there are 33 fully functioning hydroelectric generators. In total, the Columbia River is home to 14 large dams. It is a neat river that has many purposes.
After you finish reading this article, you will know exactly where the Columbia River starts and neat facts about this massive body of water.
Where Does the Columbia River Start?
While this massive river starts at Columbia Lake, it does not end there. Neither do all of its water sources come from the lake. Ten principal tributaries feed the Columbia River. Tributaries are freshwater streams that flow into a larger body of water, like a river. During the river’s first 190 miles (305 km), its course is northwesterly, but it quickly branches off.
To be more specific about the river’s location, the latitude at the mouth of the Columbia River is 46°15′ N, and the approximate longitude is 124°05′ W.
Where Does the Columbia River Flow Through?
The Columbia River flows through many states and even the Rocky Mountains of British Columbia, Canada. It primarily flows northwest at the start and then sharply turns south into Washington from Canada. When it hits Washington, something interesting happens. The body of water turns west to form a natural and breathtaking border between Washington and the state of Oregon. Once it exits the border, the river empties into the Pacific Ocean.
How Long is the Columbia River?
You can’t learn about the start of the Columbia River without also knowing the length. The Columbia River is about 1,243 miles long, starting from its headwaters to its mouth at the Pacific Ocean.
Nearly half, but not quite, of the river’s course is in Canada, right before the U.S border. Two-fifths or 500 miles of the river flows through Canada. Not only is this river long, but it is deep! Experts have measured depths up to 300 feet near Oregon and depths of 200 feet in the lower parts of the river.
Where Does the Columbia River End?
Every river has a beginning and an end, the Columbia River included. The end of the Columbia River is just west of Astoria, Oregon, where the river empties into the Pacific Ocean over the Columbia Bar.
The Columbia Bar is a shifting sandbar. The waves and unpredictable nature of the river’s mouth make it extremely dangerous to navigate.
How Wide is the Columbia River?
The Columbia River is a wide river, depending on what part you are looking at. For example, the widest point on the Columbia River is 2,640 feet, but in some parts, the width of the Columbia River is just a few feet!
If you plan on enjoying a beautiful day on the Columbia River in a boat, make sure to ask your local and state parks about sizing restrictions since some streams connecting to the riverways are shallow and thin.
Is the Columbia River Safe to Travel?
Has the beauty of the Columbia River taken your breath away? Are you ready to plan your next vacation near these waters? First, consider that both private and public land surrounds the Columbia River. The Columbia River is also massive and even starts in Canada, meaning visitors have many traveling options.
Swimmers will be happy to know that the Columbia River is generally safe to swim. However, there are some parts of the river surrounded by toxic chemicals and bacteria. A notably contaminated area of the Columbia River is the Columbia Basin, which is home to hundreds of contaminated waste sites.
Surrounding the Columbia River is one of the most polluted places in the Western Hemisphere: the Hanford Nuclear Reservation. Scientists have studied the soil, water, and air in the Hanford Nuclear Reservation’s surrounding areas, and the results conclude animals like fish, otters, and bald eagles are affected by the toxins in the water and soil. The toxins lead to algae blooms that kill water life. In the 1950s, reactors dumped a daily average of 50,000 curies of radioactive material into the water.
What Animals Can you Find in the Columbia River?
There is some spectacular wildlife surrounding the Columbia River that can make your jaw drop. Since the Columbia River stretches past seven states and a small region in Canada, the environments are distinctly different. However, in most Columbia River sites, the area surrounding the river is dense woods and forests where black bears are common. Large mammals living in the mountains, like bobcats, frequently drink water and bathe in the Columbia River. In many parts of Mount St. Helen, you can also spot wolves.
The Columbia River is also rich in fish. Just a few inches or feet below the surface of the water, you can find wild salmon, rainbow trout, steelheads, North American river otters, and, less commonly, smallmouth bass. While smallmouth bass is not the most common fish in the Columbia River, there are countless competitions yearly in the Dalles, Mt. Hood, and the Columbia River Gorge.
