Default Bull sharks at Bonniville dam?

Heard from some guy yesterday that claims he works at the dam that said they have had 3 confermed bull sharks at the dam. I find this hard to believe due to the water temps being so low. anyone ever heard of bulls in the Columbia?

Nope. Bull sharks are a relatively warm water specie and would not be found in this locale. Another type perhaps, but no bull....

That's why they have caught them on the mississippi all the way north in Illinois? One thing about bull sharks, if the water is warm and there is food they will be there. Unless the Columbia is flowing really warm and we have sightings up and down the coast in the shallows I would believe it. But there are several types of sharks that are similar to bulls that like cold water I would suspect first.

As for the other freshwater sharks, do they have to be a regular fresh water type shark? When was the last flounder caught up there? It probably came with a tide.

Pretty near impossible for it to be a bullshark in the PacNW. I have heard of salmon sharks being caught in rivers, usually not that far in, but I suppose, if he was hungry chasing salmon and just couldn't help himself....

Agreed.
HIGHLY unlikely a bull shark would go into the Columbia (or even make it to the Oregon coast).
There ARE sharks in Oregon coastal waters that can handle the temp, but I have never heard of a confirmed sighting by a biologist or pro fisherman in any river.

Quote from Wikipedia:

"In the Pacific Ocean, it can be found from Baja California to Ecuador. The shark has traveled 4,000 kilometres (2,500 mi) up the Amazon River to Iquitos in Peru.[11] It also lives in fresh water Lake Nicaragua, in the Ganges and Brahmaputra rivers of West Bengal and Assam in eastern India and adjoining Bangladesh. It can live in water with a high salt content as in St. Lucia Estuary in South Africa. The bull shark is generally prolific in the warm coastal waters and estuarine systems of the Mozambique Channel and southward, including Kwa-Zulu Natal and Mozambique. The species has a distinct preference for warm currents."

As said above, bull sharks like warm water, and are not know as visitors to California waters, much less ours.

When i fished at Westport last year we ate breakfast at some little hole in the wall joint and they had a picture of a HUGE Great White shark that was caught in the bay years ago... it was for sure not a seven gill, the people working there had the whole story and there was a newspaper article on the wall with the pic. pretty crazy stuff given the size of that beast.

EVERYTHING on the internet is true so they must have been bull sharks!

Pretty hard to swallow that one.

I have heard the Bull Shark kills more humans than any other. Simply because they live in fresh water and are common in third world countries where people tend to live closely around water. South America, Indo China, India etc.

Kind of wish it was true. They would prob make lunch out of Sea Lions! Could be tough on water skiers though.

I know right when you wiki freshwater sharks, bulls come up along with a whole family of shark that only live in freshwater, they don't even mention the monster sized sharks that live in the St. Lawrence river.

There's a stuffed great white hanging in the Seattle Aquarium, 13' I think? Salmon fisherman caught in a net in Willapa Bay. As far as they can tell, seals were chasing the salmon and the shark was after the seals and got caught up in the net.

There was a large great white spotted off of Tacoma a few years back. Everyone said the guy was full of it or on drugs. Turns out he was the original curator for the Pt Defiance aquarium, maybe he knew his fish??

The oddest similar rumor of late (3-5years ago?) was the supposed Orca in the CR near Cathlamet....much more plausable than a bull shark.

20 years ago sealions 100 miles up stream in fresh water was unthinkable. Hungry preditors do unexpected things.

Umm sea lions have been going up hundreds of miles up the Columbia for thousands of years.

There are reports of bull sharks in Lake Michigan. Although not likely, not impossible for one (or a few) to adapt and swim up the Columbia.

It's definitely a possibility but we would have reports of them spotted off our coast before magically appearing at the dam.
