Dam is included in the 2006 Wikipedia CD Selection, or is a candidate for inclusion in the next version. Please maintain high quality standards and, if possible, stick to GFDL-compatible images.

I took the following out of the article. It was out of place. Perhaps it can be worked into the article in a different manner. Kbh3rd 23:13, 16 Sep 2004 (UTC)

Some Dutch cities are named after dams; Amsterdam (dam on the Amstel) and Rotterdam (dam on the Rotte).

Compare the usage of the word barrage.

[edit] Image of Eder dam

I'm not quite sure whether the Eder dam is really a gravity dam (I think so). Someone who knows about this stuff should review this, please. --Iediteverything 15:24, 18 Sep 2004 (UTC)

[edit] dam meaning dekametre

dam is the symbol for dekametre. I am reluctant to changing dam into a disambiguation page, but I think the meaning dekametre ought to be mentioned somehow. –Peter J. Acklam 19:45, 26 Jan 2005 (UTC)

I put a short disambiguation line in the front of the article – see how you think that works. No, I don't believe it should be turned into a pure disambiguation page linking to separate articles depending on meaning. -- Kbh3rd 23:24, 26 Jan 2005 (UTC)

[edit] First dam builders

I removed a comment about Persians being the first dam builders. Intriguing if true, but no background or reference was offered to support accuracy of this statement. The statement standing alone looks like someone adding something they "just know from somewhere". A paragraph, if not a section, on the history of dams would be good for the article.

[edit] First dam builders

This might seem funny, but I believe the first dam builders were beavers. There is no mention of anything about this. How about a least link to beavers at least? Nevermind, now I see it.  :-P

[edit] Environmental Impact

There's no mention of the negative environmental impact of dams - fish passage, altered water temperatures downstream, affects on biodiversity in rivers, soil erosion, ecosystem impacts, etc.

I added a section on Environmental Impacts which was taken off this morning. I'm not really sure why. The revision 117147121 has my edits. I'm new to wikipedia and I don't really understand why it was taken off. If someone could explain to me especially the person who took it off I would be grateful. --Rf707 22:35, 23 March 2007 (UTC)

[edit] Etymology

Wikipedia articles typically do not interrupt the first sentence with etymological information. I do not believe doing so contributes much to this article and propose removing it if good argument can be made for its continuing inclusion. I love etymology, by the way, but I don't think it belongs here. Kbh3rd 21:20, 9 July 2005 (UTC)

[edit] Spillway clarification

In the section talking about the spillway, it sounds as if it's the primary means of expelling excess water. This is not always the case. The primary means of expelling water for some dams is its flood tower (I believe that's what it is called), as pictured behind these men here:

Cedar Creek Dam

In case of floods, however, these types of dams do have an emergency spillway if the flow of water is greater than what the flood tower can handle (Picture here: http://www.cedarcreeklake.info/img/spillway.jpg).

Any thoughts?

Thanks, DannyMac

[edit] Dam types not covered

It seems like some dam types are not covered in this article, such as:

  • Crib
  • Flashboard and Buttress
  • Inflatable
  • Reinforced Tank
  • Slab and Buttress
  • breeding

Does anyone know about these types of dams? -- Kjkolb 05:36, September 2, 2005 (UTC)

I know what a Timber Crib dam is and could add details but I thought that was already in there. I am not aware of the other kinds. It's also possible to make a steel crib or concrete crib dam. I intend to add Steel dam as a type covered, as I created an article for Steel dams, unless someone has strong reasons not to do so. ++Lar: t/c 14:00, 23 January 2006 (UTC)
I'll be adding a timber crib picture soon. I think there is an inflatable dam drawing at "Design of Small Dams", US Bureau of Reclamation, 65MB pdf (I'm not sure, been a while since I looked). --Duk 17:23, 23 January 2006 (UTC)
I have added Steel Dam as a type. Ironically, the timber crib pic used is the dam that was there prior to the steel dam at the same location, and which is exposed since the steel dam is no longer impounding water. Neat! ++Lar: t/c 14:48, 10 March 2006 (UTC)

[edit] history not covered adequately

We need a separate section on the history of dams and daming.--Zereshk 23:26, 31 December 2005 (UTC)

[edit] regarding dams

(I didn't have time to go and edit this page, so can somebody do it? ( I mean the dam page, not this discussion page)). Anyways, can somebody (preferably Brendan Moody) add this: A dam is a large barrier that blocks something, eg. water. A hydro-electric dam blocks water from rushing too fast into a generator to generate electricity. another meaning for dam is: something that a beaver builds, to live in. (a beaver's dam) another meaning for dam is: a mother horse, (the sire is the father) another meaning for dam is... (ask Abbopa if you want to find out. leave a comment on Abbopa's talk page.)--24.81.2.126 03:54, 24 January 2006 (UTC)

[edit] Gravity dams

Moved from article:

(NOTE: Can someone rewrite or edit this in a more general style? The intent is not to impress us with gargon and big words, but to explain gravity dams in words and terms that are more understandable... EXAMPLE: "stability is secured by making it of such a size and shape that it will resist overturning, sliding and crushing at the toe" Thanks)

(RE: NOTE- "Jargon" notwithstanding, one should be able to ascertain that the "toe" of a dam is it's base. Such a relationship would logically follow because of where toes are located on any animal with such an appendage.)

[edit] Anicut

Anicut redirects here - so what is it? Rmhermen 19:44, 28 August 2006 (UTC)

According to dictionary.com,

\An"i*cut\, Annicut \An"ni*cut\, n. [Tamil anai kattu dam building.] A dam or mole made in the course of a stream for the purpose of regulating the flow of a system of irrigation. [India] --Brande & C.

So a dam in India? --Wirbelwind 23:37, 28 August 2006 (UTC)

[edit] External link to IRN

I'm not convinced this is an appropriate place to link the www.irn.org Internation Rivers Network per WP:EL guidelines. Please explain why this is, or is not, an appropriate link for this page. Thanks! Zue 23:46, 8 February 2007 (UTC)

[edit] Largest dams

I didn't see it in this article... but do we have a list of largest dams in the world? And, if not, where are resources to make a good list about it? gren グレン 08:43, 27 March 2007 (UTC)
