fish, boat, swim.
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.
Researches have shown that hudson river is actually the safest river to swim in the United states. As long as you do not swim in the deep places, you are fine.
no where is clean to swim
No, because a river always has a source, and as you get closer to it, the river is blocked by locks, dams, or channels. More than 2000 miles of the Mississippi is used by barges, ships, and boats of many sizes, along a winding path from Minneapolis to New Orleans (1600 miles apart) and out into the delta.
Well, if you want to literally "swim" all the way from London to Paris, you're going to have to swim downstream the Thames river, then cross the English Channel, and then swim upstream the Seine river until you reach Paris... Mmmh that may take a while! But if you want to simply cross the Channel between England and France at its narrowest point, the world record is about 7h54 I think, but the average time is about twice as much or 13h.
I'm guessing not as long as it would take for you to swim there.
Oh, dude, you bet there are brown trout in the Mississippi River! They're like the cool kids who decided to swim upstream and hang out in the Midwest. So yeah, if you're ever fishing in the Mississippi, keep an eye out for those stylish brown trout just casually chilling in the water.
Rio Grande river is 1,885 mi (3,000 km) long.
No, but a word like swine would be. Swim has the short I as in dim and slim.
they swim across river such as Mara river that separate Tanzania and Kenya, over 3 million wildebeest swim across the river every year.
Sharks are not typically found in the Mississippi River. However, bull sharks are known to swim in brackish and freshwater areas, so it is possible for them to enter the river from the Gulf of Mexico.
