Talk:Endorheic basin

message: Terminal lake now refers to endorheic basin, but a basin is not a lake. A lake can be found in the bottom of a drainage basin, but they are not one and the same. Furthermore, the term terminal lake is easily a factor hundred thousand or more widespread and known than endorheic lake, so the choice of principal word seems somewhat odd for me as a geographer. -- 66.176.181.109 21:25, 11 November 2007 (UTC)

message: Shouldn't this article be at Endorheic basin since that it was it is about?  Endorheic seems odd as an article namefor te topic since it technically is an adjective.  Eluchil404 22:24, 6 August 2006 (UTC)

message: Would the Zeller See in Austria not count? It has no outflows. I'm not expert enough on the definition to make the change to the article myself. jlang 17:28, 21 February 2007 (UTC)
replies: text: This article's definition of an endorheic system precludes any underground drainage.  The Zeller See article says that for that lake "water loss is solely by evaporation or underground seepage."  That would seem to exclude it from being described as an endorheic system.  (I'm not an expert on either the definition of endorheic or the hydrology of the Zeller See.) --Kbh3rdtalk 20:20, 22 March 2007 (UTC)

message: Isn't the Colorado River an endorheic basin? After all, it dries up before making it to the Gulf of California. If yes, this is a great example to discuss, since it is endorheic purely because of human activity. If you account for this human activity, this actually would make the Salton Sea the low point of the Colorado River endorheic basin, since this is where the irrigation canals are directing most of the water that would otherwise reach the sea. (Most other diversions lead back to the river, such as diversion into Phoenix, which return via the Gila River).
I'm not sure how folks view this idea, but it's certainly worth some discussion.
On this topic of uniqueness, Crater Lake should maybe be mentioned as a rare example of a wet climate endorheic basin. —The preceding unsigned comment was added by 63.231.60.142 (talk) 04:33, 25 February 2007 (UTC)
replies: text: Don't know, but if I had to guess I would think it isn't considered a basin (see Mojave River for something vaguely similar, or rather would be similar if it headed towards the ocean). In any event, what matters is not where you and I would draw the line, but where reliable sources draw the line. So this is more a matter of research than discussion as such.

replies: text:  The map appears to show the Colorado River basin in North America as endorheic which to me seems rather misleading. The Colorado River after all used to flow permanently into the Gulf of California. Now it only flows into the sea intermittently because of human activity such as damming and water extraction. However it does still flow into the sea reasonably regularly, the change is only recent and human induced, which to me would tend to make me think of it not as an endorheic basin.

replies: text:  I believe that you are misinterpretting the map, which shows the Great Basin, not the Colorado River basin.  They border each other, and both squeeze into that area in southern California near where the Colorado enters the Gulf of California -- relatively near, given the scale of that map.  The Salton Sea, e.g., is in that area and is certainly endorheic.  See the maps on the Great Basin page.  --Kbh3rdtalk 02:30, 1 September 2007 (UTC)

text: Once in a blue moon, the Okavango has enough flow to reach the Cuando River, which connects to the Zambezi, and hence the sea.  This is entirely natural (as its normal state of not making it there.  But if you start including intermittent areas you run into gray areas like this.  I think most would argue the Okavango qualifies and is indeed a prime example of an endorheic basin. Aapold (talk) 15:47, 7 June 2009 (UTC)

message: This body of water drains through aquafers into the Klamath River Basin, which drains into the Pacific Ocean. It wouldn't be an endorheic basic with the defination given.

message: The western part of inland central Australia is shown in pink,  as if it drains to the sea.  This is incorrect.  Most of this area has no drainage to the sea at all,  even in abnormal rain conditions.  If a lot of water arrives,  it ends up in the countless dry salt pans.Eregli bob (talk) 16:41, 17 August 2013 (UTC)

message: The article states that "Endorheic regions, in contrast to exorheic regions which flow to the ocean in geologically defined patterns, are closed hydrologic systems." I disagree, based on my understanding of hydrologic, namely that it includes evapotranspiration and rainfall. If my understanding is correct, rain evaporated from other basins would fall in an endorheic basin and water would indeed escape the endorheic basin and fall elsewhere in the world. 209.2.20.17 (talk) 17:00, 16 September 2013 (UTC)

message: I have been trying to find information regarding farm ponds. Man made farm ponds are often endorheic and my mother-in-laws farm pond is one such pond. It has a very small catchment area, almost never runs over, and the soil in the area is clay, so there's probably little or no seepage. The water level varies, being low during dry seasons and higher during rainy seasons. I have found very little information regarding testing for salinity levels, fish, plants. 162.40.172.185 (talk) 06:26, 2 November 2013 (UTC)

message: The page was recently moved to "Closed sea", however there was no discussion and the article was not modified to fit the new name. The name "closed sea" is not even mentioned in the article except for the dab at the top. This is about basins with no external drainage and most don't have a resident body of water or "sea" except temporarily. Given that - the name "closed sea" is simply a misnomer. Thoughts? Vsmith (talk) 15:49, 9 May 2017 (UTC)
replies: text: Either way it should have stayed  "Endorheic basin" until such a major change was discussed, and it should be someone willing to related work on the article doing such a move. Beyond that, I'm no expert on what the most common term is, or whether such a term is unambiguous. But they certainly are very different.  One is about basins, and only a small fraction of those include a sea. North8000 (talk) 20:30, 9 May 2017 (UTC)

replies: text: Agreed. The technical literature I've consulted seems to agree that endorheic lakes are defined by most water being lost by evaporation, and not by surface or subsurface flows. I will update the article, with sources. --Macrakis (talk) 20:16, 19 July 2020 (UTC)
replies: text: If we get that solidly established, then the list is going to need changing.  There are some in there that either stated or inevitably have subsurface drainage.  BTW  subsurface can be seepage rather than drainage.    Even the smallest amount or peculation through the soil (even the small amount through clay) makes the big difference on whether or not it is freshwater.   North8000 (talk) 21:46, 19 July 2020 (UTC)
