Photo request

Like, not a satellite photo, but a photo of part of the river from the ground, perhaps in Kyzyl? —Keenan Pepper 17:27, 2 July 2006 (UTC)

Water volume of the drainage basin

I removed this unsourced claim from the article:

Its watershed, which includes the world's largest (by volume) freshwater lake, Lake Baikal, holds more water than any other river system.

Because it 1) lacked any citation. 2) is quite likely wrong, the Amazon has a drainage basin 5 times the size (with 20 times the water discharge), but more importantly the St. Lawrence River has all of the great lakes in it's drainage basin, these 5 lakes together hold significantly more water then Lake Baikal. If one reads the Great Lakes article one can find a sourced claim that it's the largest freshwater system in the world.

If you want this claim up in this article you need to source it. Mecil 13:30, 8 April 2007 (UTC)

While not taking a stand on the claims verifiability, I think you may be misinterpreting the first part. Lake Baikal is the largest lake, by volume.

I just added up the volumes of the five North American Great Lakes. Baikal is about 20 percent larger than all of them put together. Water in Lake Superior dwells for 99 years. Water in Lake Ontario dwells for 6 years. That is, water that flows into Lake Ontario at Niagara enters the St Lawrence six years later. So how much of the water in the St Lawrence basin is in the rivers and smaller lakes? Well, how long does it take water that flows into Niagara to pass Quebec? city? I don't know. I am going to guess about a month. If it were on the order of a month then the volume of the St Lawrence proper would be 1 / ( 12 * 6) that of Lake Ontario, about 1 / ( 12 * 99 ) that of Superior. In other words, well under half of one percent.

My back of the envelope calculations are obviously not a viable reference. But I think it shows that the claim is credible. The Amazon may have ten times the flow of the Yenisie and St Lawrence put together. But it lacks any big lakes whatsoever. And its dwell time must be less than a year, because the lower reaches have annual floods.

5th longest?

According to this article the river is the 5th longest in the world, yet according to http://en.wikipedia.org/wiki/River#River_lists it is the 10th longest. I know that measuring the length of rivers is far from an exact science, but does anyone know which is more approximately the correct position, and does anyone have any suggestions as to what we should do to make the info here on Wiki more uniform as regards these lists? peace Warchef (talk) 12:51, 3 February 2008 (UTC)

I think the difference is one of definition. The furthest headwaters of the Yenisey are not the Yenisey's own source, but the Angara's (rather like the situation of the Mississippi-Missouri). Therefore if one measures from the source of the Angara you get a longer distance from the source of the Yenisei. Booshank (talk) 20:41, 18 August 2009 (UTC)

Navigation section

It starts with sentences: "The canal was used one last time in 1942, when three steamboats and a cutter managed to make their way from the Yenisei to the Ob, but the passage was extremely difficult. The canal is now fully abandoned. It is occasionally reached by tourists using canoes, cars, or bicycles, or on foot." I think these are coming from article Ob–Yenisei Canal and should be removed. If anyone feels like reinserting improved version of these sentenced going well with flow of article, go ahead, please. --Ruziklan (talk) 07:40, 30 March 2010 (UTC)

Maximum depth and outflow depth

The maximum depth is 24 metres ... The depth of river outflow is 32 metres. Apologies, I'm no expert on geography, I contribute elsewhere & I'm just a reader of this interesting article. River outflow is frequently used elsewhere. Could someone kindly provide a definition and internal link? Thanks in advance JRPG (talk) 08:05, 19 August 2015 (UTC)
