Talk:List of largest dams

message: I'm surprised this dam doesn't get even a mention. It is the third largest hydroelectric dam in the world, and produced the second-most electricity of any in the world as of 2020, only surpassed by the Three Gorges Dam.  — Preceding unsigned comment added by Ianbrettcooper (talk • contribs) 15:11, 21 April 2023 (UTC)
thread_title: Why no Itaipu Dam?

message: I was surprised to not see this here, as it's one of the world's largest for sure.  According to the World's Largest Dam website in the references, it's 43.7 million cubic metres, higher than Aswan's 43....but on the World Lakes Database its stats are:
::Surface area [km2] 	1,779
::Volume [km3] 	70.3
::Maximum depth [m] 	166
::Mean depth [m] 	43.3
::Water level 	Regulated
::Normal range of annual water
::level fluctuation [m] 	16.8*
::Length of shoreline [km] 	1,770
::Residence time [yr] 	2.2
::Catchment area [km2] 	72,000
::* With 32 m the maximum, allowable (1972-1987)
And on www.economy-point.org/w/wac-bennett-dam.html's listing it's 70; the rest of their stats are garbled for some code-conversion reason but the page includes the cryptic comment:
::The W.A.C. Bennett dam with Hudson's Hope in Canada is one of the largest dams of the earth. It is after the size of the memory space on place 9.
By which I mean it's ranked ninth... (??).  Not sure of how to add it, although I know the tables; I'm just uncertain of the units; the volume of Lake Williston, if added in, would make it one hell of a lot larger.....Skookum1 (talk) 06:12, 24 February 2008 (UTC)

message: A tailings dam is just a pile of mine waste, which can be arbitrarily large, with a little water trapped behind it. It does not impound a reservoir and should not be included in this list. HowardMorland (talk) 18:02, 29 January 2010 (UTC)
replies: text: I agree, it should be removed and maybe something should be included in the intro about the types of dams. Like, those serving some sort of civil purpose. Also, I plan on adding a few/fixing this list up.--NortyNort (talk) 14:29, 13 February 2010 (UTC)

replies: text:  Oh darn, my question about which Syncrude Dam was prophetic. I've now got a 1994 reference (18th International Congress on Large Dams) to a DIFFERENT Syncrude tailings dam, the MLSB dam, which on completion (1995) was meant to have a maximum height of 88 metres, and is more of a water storage dam than a tailings dam. It could easily be bigger than the SWSS Dam, the reference gives a projected structural size of 720 million cubic metres, which includes "beach and shell".Mollwollfumble (talk) 04:57, 14 December 2010 (UTC)

text: Just a note on the Chapeton Dam article which I was just researching for a possible creation. It seems to be part of the Parana Medio Project and I found no evidence construction starting (Pretty sure the .de article is wrong). Locations for both the Chapeton and Parana Medio are consistent, about 25-30 km north of the Parana/Santa Fe border. It is designed to cross the island here: . It appears the dam was killed in 1999 after being reintroduced in 1996. No idea on the River Plate or Rio Plato dam as well.--NortyNort  (Holla) 04:22, 29 January 2011 (UTC)

replies: text: Thanks for challenging and scrubbing the list, especially adding the dam types. I remember there was a few problem entries a few months ago that were caught...reservoir size was used instead of the structural size. I don't think anyone has overhauled it and this list was in my mid-term scope of things to do. Regarding Syncrude, I am not terribly familiar with the dam and don't like tailings dams on the list but after all, it is a dam. If you are interested in dams, there is WikiProject Dams which is focused on improving these articles. We have a to-do list and your insight would be great.--NortyNort  (Holla) 03:47, 12 December 2010 (UTC)
thread_title: Structure Volume

message: Numerical Sorting is broken in many of the columns, resulting in text-based sorting, which is inaccurate.  I suggest we do not use the dash or slash (both of which break numerical sorting) to indicate uncertainty, but split into two columns if the uncertainty information is important.  — Preceding unsigned comment added by Wrennj9 (talk • contribs) 21:07, 4 June 2012 (UTC)
replies: text: That's not enough to enable numerical sorting.  I think it will be necessary to add a column for references and move all the references out of the numerical columns. M Carling 21:51, 18 December 2013 (UTC)

message: Undid the incompetent edit of Jan 2012 that changed "Oahe" to "Guri." Note that Guri needs to be added -- but I don't know the right numbers.

message: I suspect that the Benmore Dam belongs on this list, though official sources (and therefore our article) are hopelessly confused as to the volumes of earth in the dam and water behind it. If anyone can find out some accurate figures, it's be very helpful! Grutness...wha? 13:08, 30 July 2013 (UTC)
replies: text: These two sources ,  state around 11-12 million cubic meters of fill which is considerably less than the smallest on the list, San Roque Dam (35 MCM).--NortyNort  (Holla) 20:18, 30 July 2013 (UTC)

message: I don't understand. It's probably world's largest dam by volume, but no one mentions it.  — Preceding unsigned comment added by 104.33.81.62 (talk) 06:53, 7 March 2015 (UTC)
replies: text: Do you mean the Delta and Zuiderzee Works? They are a system of dams, barrages, etc. and this article is on a single largest dam, by volume.--NortyNort  (Holla) 13:56, 7 March 2015 (UTC)

replies: text: i agree with this question.  Hoover is listed on the "tallest dams" page (but the Oroville Dam is listed on both pages; possibly other dams, too).  and Hoover is listed on the "reservoirs by volume" page (but the Aswan Dam is listed on both pages; possibly other dams, too).Colbey84 (talk) 08:49, 13 May 2016 (UTC)
