1. As Lake Van is in Turkey, the Turkish name of the lake in Turkish should be displayed before any other language. 2. Can anybody explain the relevance of Ottoman-Armenian population, Armenian genocide, or Treaty of Sevres, which are lisred in the "See Also Section", with Lake Van?

Needs better pictures
The Lake deserves better pictures.

Is Lake Van saline or not?
I have noticed a contradiction between this article and the article on Kurdistan. This article describes Lake Van as a saline body of water; the Kurdistan article describes Lake Van as a non-saline body of water. Would those of you working on these two articles mind sorting this out? I am posting this observation on the other site's Talk page, also.RNavigator 13:11, 5 June 2006 (UTC)
- Here's some information from http://lakes.chebucto.org/saline1.html
- A widely accepted demarcation line between fresh and salt water occurs at 3 grams per litre, or 3 o/oo. (Freshwater lakes contain 0 - 3 g/L of salt and saltwater lakes anything over 3 g/L). Here are data for some lakes:
|Great Salt Lake||150-280|
|Dead Sea (Israel/Jordan)||over 300|
- I think it's clear that Van is definitely a salt lake, but obviously much less salty than the Dead Sea.
- Various salts contribute to the salinity, not just sodium chloride. In particular, the presence of sodium carbonate and sodium bicarbonate in some salt lakes makes the water alkaline. Lake Van has a pH of 9.8 which is distinctly alkaline (data from http://www.internationales-buero.de/_media/Abstract-Sari.pdf).
- Hope that helps. Euchiasmus 05:25, 6 June 2006 (UTC)
I provided them, its good enough. Artaxiad 19:12, 28 March 2007 (UTC)
Transliteration of Armenian name
Can someone please transliterate the Armenian name? Meursault2004 12:10, 29 September 2007 (UTC)
Lake Van is a notable lake because it's so deep and is very large for a salt lake. It would be good to be able to list some accurate measurements for the lake, such as depth, area, volume height above sea level, etc. There are quite a number of differing figures for these, so I thought compiling the various sources here might help establish the most reliable figures. Any general comments would be welcome, too. Rupert Clayton 14:25, 26 October 2007 (UTC)
Bold (where used) indicates figures that appear to have most corroboration. Data sources are listed at the end.Rupert Clayton 17:16, 1 November 2007 (UTC)

Many reports of research around Lake Van in various fields contain basic data on the lake's measurements. Because of this, modern sources in seemingly tangential specialties may have more accurate data than older geological, limnological, and bathymetric sources.

- Lake Van saw a rapid rise in the level of its waters in the 1990s. I don't have a source to give specific data but it was a very substantial increase (well over 3 meters, accompanied by large areas of agricultural land being flooded). For example, the jetty of the ferry port at Tatvan was operating normally in the 1980s but was completely under water by the late 1990s and a new one had to be constructed. All figures for surface area, depth, shoreline length, etc., that were compiled before the 1990s will now be inaccurate. Meowy 15:53, 1 January 2008 (UTC)
Water level rise and railway deviation
If the water level rises after a railway deviation is built to bypass the Lake Van ferry, that investment would be wasted. How difficult would it to build an outlet tunnel to drain the lake and protect that railway? Tabletop (talk) 01:23, 31 October 2008 (UTC)
I added a reference to the pH, but the article still needs a reference about the extraction of economic resources. I'll see what I can find, but someone searching Turkish sources would be useful also. --KP Botany (talk) 19:38, 30 December 2008 (UTC)
