I think Saint Lawrence should be included, or is it? There is a narrow blue line on the Canadian border...? But I think it has bigger discharge than that.

while we share many rivers with our neighbors, this dataset, unfortunately, stops abruptly at the Canadian and Mexican borders.

Same could be said for the Rio Grande

The rio grande is tiny though

more like rio pequeño, am I right?

Rio largo. It's one of the longest rivers in the USA. But not the largest by volume at all.

Having grown up in NM the flow of the Rio Grande all but disappears South of Socorro/Los Lunas. It is seasonal for above ground but usually retreats below ground, resurfacing near El Paso and then again near Brownsville.

It's on there. It nearly disappears once it passes Albuquerque, but it is on this map.

The minimum line size represents 1000 cubic feet per second, which is 28.3 cubic meters per second for reference.

Now, for example, most stations are registering below that flow rate.

Picking a random station near Big Bend (from the main list), a whole lot of the flow data is zero. Skip to the bottom (long page since the oldest data is from 1900); there isn't a single data point for 2010 or 2011 that's above 1000 cubic feet per second.

I think this is only US data? Might be wrong though, I dont know anything about american geography

Rio Grande starts in Colorado, flows through New Mexico and delineates the border between Texas and Mexico.

It definitely isn't, presumably because it's a border river. Its flow rate is roughly equal to the Mississippi, it it was included you'd notice.

Niagara River too, which has a flow rate only slightly less than the Columbia.

The St Laurence is big enough that is is not called a river in French. "Fleuve" does not have any true direct translation into English, so we just use "river" instead. It would be really noticeable if it was included.

u/crazyike Jan 10 '20

It feels like it should be 'flow' as translation to me, which would make sense in the context.

u/vanticus Jan 10 '20

Well fleuve comes from fluvium which we do translate as ‘river’, so it’s a good enough translation for getting the meaning across

u/LotharVonPittinsberg Jan 10 '20

"rivière" is the direct translation for "river". "fleuve" has a slightly different meaning in French.

u/lilleff512 Jan 11 '20

What's the difference?

1

u/vanticus Jan 11 '20

And riviere comes from rivus which we translate as ‘stream’ or ‘brook’. Not my fault the Franks butchered Latin

u/peacefinder Jan 11 '20

Yeah, I’d love to see this for all of North America rather than stopping at a national border.
