Error in "List of world's tallest dams"[edit]

The following is pasted from my "talk" page. JW in TX (talk) 18:29, 19 November 2007 (UTC)[reply]


Dear JWinTX, I noticed that you have edited the table. There is an error in the table, but it was too difficult for me to edit that table. So I hope you can make a correction: The Alvaro Obregon dam (number 11 in the table) is missplaced and should be removed. The height is much lower than 260 m (this can be easily verified with Google earth). Height may be about 88 m, which is in the table quoted as the width of the dam. This error also appears in some other places in Wikipedia (e.g. in the German version of the table and in article about Alvaro Obregon). Also I recommend that Rogun is deleted from the top of the table. There are very many places in the world where as high dams as the planned Rogun could be built. The construction of Rogun was in a very early phase when it was abandoned after Soviet Union collapsed. Afterwards a flood viped away what was visible of the construction site. It is easy to verify with Google earth thart almost nothing remains. If the Rogun dam is ever built, the dimensions might differ considerably from those of the original plan. The footnote referring to the Rogun plan could be placed on the row of Nurek dam (number 2 in the table), because Nurek is downstream of the Rogun site.

A number of the rivers are listed in the municipalities column. May I suggest the order of these columns are swapped because not all dams are associated with cities but all are with rivers. —Preceding unsigned comment added by 82.69.16.174 (talk) 20:46, 18 June 2008 (UTC)[reply]

Add A Section to the Table?[edit]

I noticed several of these dams listed aren't even completed and are even in the preconstruction phase, so I suggest adding another headline to the table such as Completed (Yes/No) or maybe Progress (Idea/Completed/Under Construction). I think it would be good because technically I have a concept for the tallest dam in the world and I should be able to put it on this list, it's 80000000m tall. Well not really but you get my point, conceiving and building are two different things just like physically existing and conceptually existing are two separate things.

What about another section describing the type of dam (concrete arch, CFRD, clay core etc)? —Preceding unsigned comment added by 82.69.16.174 (talk) 20:23, 18 June 2008 (UTC)[reply]

Two years late but I am working it. U/C will indicate Under construction.--NortyNort (talk) 12:38, 3 July 2010 (UTC)[reply]

Table edits[edit]

I noticed there were some dams on this list below 100 m and some above 100m that probably weren't on the list. I want to "revamp" the list, removing "smaller" dams that really don't belong there. Also, I think it may be a good idea to remove the Municipality column and add a dam Type column and maybe Notes. Any suggestions?--NortyNort (talk) 13:57, 13 February 2010 (UTC)[reply]

I am going to work on revamping this list. I have deleted all dams below 100m. The are thousands of dams in the world between 39m and 100m.--NortyNort (talk) 15:06, 26 June 2010 (UTC)[reply]

Dam height[edit]

How is a dam's Height defined for this article?

This may seem like a stupid question, but let me explain. There are several ways to assess a dam's height.

  1. Measure from the foot of the dam foundations to the crest of the structure. This is the vertical size of the dam strucure.
  2. Measure from the stream bed to the crest of the structure. This is the height of the structure above the ground.
  3. Measure from the mean water level downstream to the mean (or maximum) water level upstream. This is the head of water retained by the dam, or the fall of water that can be obtained. In some cases the dam is a water level control structure but reservoir outlet is taken through an underground tunnel to a much lower level. e.g. Manapouri.
  4. In some structures the material beneath the dam footing is prone to seepage and a concrete grout has to be pumped into it to reduce wter flow. Is this grouted depth excluded or not?

I am assuming that any of these heights could be used in the article. - Cameron Dewe (talk) 10:23, 13 February 2011 (UTC)[reply]

srisailam dam height is not correct in the table !!![edit]

i am surprised !!

The height of srisailam dam is wrongly given in the table and it needs to be corrected; you can easily verify this (if i am correct) by clicking on the link itself, the article about srisailam in wiki itself gives the correct height.

(http://en.wikipedia.org/wiki/Srisailam_Dam#cite_note-0) — Preceding unsigned comment added by 76.185.175.30 (talk) 10:56, 10 October 2011 (UTC)[reply]

According to that source, the height is 145 m. I made the correction (again) in the article. I also found another source that supports 145 m as well. It appears to be around 145m high, as opposed to 241m in photos as well.--NortyNort (Holla) 01:37, 11 October 2011 (UTC)[reply]

Incorrect title[edit]

This page is currently a list of the tallest human-created dams, not the tallest dams. The title should be changed or the table expanded to include natural dams. KingSupernova (talk) 01:45, 4 September 2022 (UTC)[reply]

Usoi Dam is already mentioned in the article lead, no need to rename the article. Feel free to create a separate table with natural dams. Jklamo (talk) 11:53, 4 September 2022 (UTC)[reply]
That's exactly my point. The inclusion of Usoi Dam in the lead makes it clear that the article is talking about all dams, not just human-created ones, but then there's no table for those. KingSupernova (talk) 18:29, 4 September 2022 (UTC)[reply]
Rejoice, then, for the table now includes both Usoi Dam and the landslide dam that impounds Lake Waikaremoana! LucasBrown (talk) 20:29, 28 February 2023 (UTC)[reply]
