Every see those movies about times past, usually colonial America, or the wild West, or long before, where people would swim underwater in those nice clean rivers?
Can you imagine rivers being that clean? Not if you lived in Louisville, on the Ohio River.
I tried to look it up on line, about the History of clean rivers, when rivers were cleaner, and if they were once cleaner, and all that comes up is the same information about what they're like now. Is there no History of rivers ever being clean? Was there ever a time when someone could stand by the Ohio River and see anything but murk? Jefferson wrote that it was a beautiful river back in the 18th century, so apparently it once was totally the opposite of what it is today.
But is there even a river today that we can look at to imagine what the Ohio River was once like?

Am I the only one here who looks at today's stinking rivers and wonder what they were like just 200 years ago?

I don't believe that all rivers were, at one time, clear and that it is only man made erosion that makes them turbid. I note that long before humans arrived on the scene, erosion was occurring and rivers were washing mountains into the sea and gouging large canyons/valleys.
I was interested in a show I watched that hypothesized that at one time, the Amazon River flowed the other way...west,. Before South America separated from Africa they think it flowed from what is now the Sahara, across what is now South America into what is now the Pacific. Continental drift separated SA from Africa and pushed up the Andes which blocked the ancient Amazon and caused it to start flowing east.

Am I the only one here who looks at today's stinking rivers and wonder what they were like just 200 years ago? Well, not exactly... I've not thought specifically about "Rivers"... But, I have wondered what places that I have been to, looked like long ago, before they were heavily populated... I've even wondered what my neighborhood looked like, just 100 years ago... Also... I watched a documentary from 2009 called " Holy Grail In America" which discusses a possible "Knights Templar" exploration of North America in the Mid-1300s and the 1362 carving of the Kensington Runestone found in Central Minnesota in 1898... And I think about the North American Western Migration, from the late 1700s into the 1800s, involving the 'Wagon Trains' traveling for weeks across the "Wilderness" to reach the West Coast. ... Just think about these explorers/settlers traveling 1000s of miles across an unknown continent without roads and communities and such, while seeing nothing but the untouched land, mountains, rivers, and forests, just as mother nature created it... As well as... Stumbling across the Grand Canyon without having any knowledge of it's existence... Well, that experience must have been mind-boggling, and incredible for them to think they were "the first ones" to experience this huge new "world"... ... Today, we have maps, pictures, documentation... Planes, Trains, & Automobiles... People living everywhere... and so on... Sort Of... Clean flowing rivers of water?Yes... Imagining what the "Mighty" Mississippi was like, back when Explorers/Settlers experienced it during the North American Western Migration?Sadly, No... Our world is just too different now... And, it's too dirty as well, too. ... It's like looking up at the stars... With our modern day smog, and light pollution... It just isn't the same. It's too bad, that we all have to imagine, what all that was like, for our ancestors...
