For all its bulk on this map the Mississippi is a modest river by world standards, discharging around 16,800 cubic metres per second at its mouth against roughly 209,000 for the Amazon, which means the largest river in North America carries something close to a twelfth of the water of the largest in South America.

Clear visual message – nice job!

The Niagara River should be 200k cfs, don’t use the falls flow rate which is controlled by hydropower diversion.

Love this map, more continents would be amazing!

The Ohio got screwed. It’s the river that flows to the gulf.

You can really see why people were so interested in, and hopeful for, a Northwest Passage connecting the Mississippi/Missouri with the Columbia, even if turned out they needed to build some canals or do some portage. They’re sooooo close on the map if you don’t have a grasp of the scale of the Rocky Mtns.

The Rainy River system (MN-ONT border)is particularly interesting. it is a series of large lakes that is constantly moving and only in very short rapids and falls between them for much of its length are you reminded that all of it is part of one system.

Damn that rio is a lot less grand than I imagined

I would think the Hudson may be under counted because it reversed with the tides

I think this highlights just how much of a problem water supply is in the southwest. It’s crazy that cities like Phoenix and Las Vegas are some of the largest in the US, they absolutely should not be.

Poor Rio Grande. The Albuquerque section has been completely dry this year for the most part.

Why is it the Mississippi with Ohio and Missouri as tributaries versus named for one of those rivers with a Minnesota river as a tributary?

Has anyone ever boated up the Mississippi/Missouri, then down the Columbia? Other than L&C, that is. Would be like the Iditarod of kayaking.

Every now and then people ask „why is Arizona more populated/richer than New Mexico:“ the contrast here between the Colorado and the Rio Grande is probably the biggest reason.

Why does it look like the Coosa and Tennessee rivers connect?

I always feel like the Susquehanna punches below its weight for the size of river that it is. When you look at a satellite view it looks quite massive and cuts straight through difficult mountainous terrain. Harrisburg, PA is like the biggest city on it, there isn’t really a big city at its mouth. Compared to other Northeastern rivers such as the Hudson, Delaware, Connecticut, even the Potomac you hear about a lot more.

I remember seeing the Rio Grande and thinking, that’s not very grande.

Fun fact: Idaho actually has an ocean-going port at Lewiston.

Most of the Great Lakes drainage basin is in the US and ought to be included.

“the largest discharging about 10 cubic kilometers per hour (2.7 million m³/s, 13 times that of the [Amazon River](https://en.wikipedia.org/wiki/Amazon_River)).[[6]](https://en.wikipedia.org/wiki/Missoula_floods#cite_note-hill-6)[[7]](https://en.wikipedia.org/wiki/Missoula_floods#cite_note-Lehnigk-7) Alternate estimates for the peak flow rate of the largest flood range up to 17 cubic kilometers per hour.[[8]](https://en.wikipedia.org/wiki/Missoula_floods#cite_note-Bjornstad-8) The maximum flow speed approached 36 meters/second (130 km/h or 80 mph).”
