Good question there was never a bull shark in the delawere river plus a shark can go from an ocean to a lake or a river but there might of been one but the people should not have went swimmming there that there was a shark in the river but good question! :)
yes
There is no verifiable information of a shark having ever been found in the Colorado River. However, the Bull Shark is capable of living in fresh water, so it is possible.
the bull shark can swim in tropical rivers for brief amounts of time and there is the River shark which is native to Australia and Asia
No

the Hudson river near the science hall of fame i think its at shark river
No. Sharks are primarily saltwater fish. While one shark did swim a distance up the Hudson river, the Allegheny River is too far from the ocean. In order to get there a shark would have to swim up half the Mississippi River and the entire length of the Ohio River.
