The Columbia River is known for being the fourth-largest river in North America, flowing over 1,200 miles from its headwaters in the Rocky Mountains to its mouth at the Pacific Ocean.

However, due to its location inland, it is unlikely that any sharks would have been able to swim up the river, as they require a specific saltwater environment to thrive.

Despite this fact, there have been a few notable sightings of sharks in the Columbia River over the years.

One such example occurred in 2016 when a shark was videotaped attacking a seal near Astoria Oregon at the mouth of the Columbia River. 

However, this occurrence was an unusual event, likely a result of the shark getting lost in its search for food.

Another possibility is that the sharks seen in the Columbia River could have been Bull Sharks.

Bull Sharks are one of the few species of sharks that can adapt to a freshwater environment and have been known to swim hundreds of miles upriver in search of prey.

However, no scientific evidence has been found to support claims of any Bull Sharks in the Columbia River.

So, while there have been a few rare sightings and tales of sharks in the Columbia River, it is unlikely that any could survive in its freshwater environment for long.
