cedros Posted October 19, 2020 Report Share Posted October 19, 2020 According to Conagua the lake level is dropping already. It is almost a meter lower that his time in 2018 and about 60 centimeters lower that this time in 2019. Not a good sign for the future. Normally the peak is reached in late late October or November.

johanson Posted October 19, 2020 Report Share Posted October 19, 2020 I don't want to remember how many meters lower the water lever was around 2001 to 2003 three or so. Quite a few meters. The Cota during that period got down to just above 91 meters which is much lower than it is now which is about 95.5 meters which can be seen at the below link.

Maybe they haven't opened the dams on the Lerma river yet. A lot of development happening on the north shore of the lake. They are already fighting over who is to get access to the limited water supply. Link to comment Share on other sites More sharing options...
bmh Posted October 19, 2020 Report Share Posted October 19, 2020 oh please can we worry about something we can do something about? The lake is plenty high... timme to worry about somthing else.. 1 4 Link to comment Share on other sites More sharing options...
cedros Posted October 19, 2020 Author Report Share Posted October 19, 2020 Don't worry about it then-let others. The lake is not pretty high. Remember it is only about 31 feet deep. Where I come from a lake this wide would be hundreds of feet deep. It is after all Mexico's largest lake. Without the lake this area would just just be a series of scruffy towns. When I go NOB a common question. I am asked is how is the lake level. Link to comment Share on other sites More sharing options...
AndyPanda Posted October 19, 2020 Report Share Posted October 19, 2020 It is a topic of daily conversation. But I agree with bmh... I would rather keep it that way: off the boards and maybe over lunch. This is a board for assistance, and constant ruminations about the rainy season and the lake level are pretty boring. Not to mention the fact that there is nothing we can do about it. Less worry means more happy, right? 3 1 Link to comment Share on other sites More sharing options...
bmh Posted October 19, 2020 Report Share Posted October 19, 2020 Cedros , the dry season has started and the lake will go down, that is the way nature works. If/when it rains too much upstream they will release water otherwise we will have to wait until next june or July for the water to start coming back up. It has been that way for centruries whether people worry about it or not, Who cares what the people up north ask.. the lake is what it is... let it be. When we bought the house you could barely see the lake and we live a couple of houses from it.. We could walk or drive to San Juan from the Ajjic pier amongst trees and cattle.. I liked it that way too. when the water came back all the trees died..and the great walks were over.. the people on the lake stole more federal zone and now there is no walking possible.. not a great improvement. The routart a well known guide to the French took off Ajjc and Chapala from their routes because the lake was going to disappear and was dying and then there were projects to help the lakes and to raise money for the lake then they brought the Huicholes and the Virfing of Zapopan , the weather pattern changed and the lake started filling up again. Yes lets worry about something we have control over or better let us not worry and let is spend our energy changing things we can change.. 2 Link to comment Share on other sites More sharing options...

Why can't it be one for knowledge also. bmh you are missing the point. It is going down much to early. There is very little here that we have control over but we can have input here. 3 Link to comment Share on other sites More sharing options...

I'm not aware that any of us have control over what is allowed to be posted on this Forum... other than the obvious. But I do know an iron clad way of escaping anything that any of us may either not be interested in or find boring..... just don't read the Post. Skip it. That way you are happy and others who may find the information/discussion relevant to their lives can carry on. I can't tell you how many topics I never read nor how many posters I have blocked as unimportant to me. Then when I am through scanning/reading the topics I am interested in I just click the 'Mark Site Read' button. Takes the 'highlight' off. 3 Link to comment Share on other sites More sharing options...
slainte39 Posted October 19, 2020 Report Share Posted October 19, 2020 Cedros likes "to worry" in the public domain.......😀 2 Link to comment Share on other sites More sharing options...
AndyPanda Posted October 19, 2020 Report Share Posted October 19, 2020 Hmmm. if I don't read a post or follow a thread, I don't actually know how important or boring it is. Therefor I don't know if I should read it or not, until I've read it. What I find interesting is, even though I was agreeing with bmh, now I'm getting comments as if I was arguing with cedros. Looks like I can't win either way. 1 Link to comment Share on other sites More sharing options...

AndyPanda Posted October 19, 2020 Report Share Posted October 19, 2020 I beg to differ, on two counts. First, I don't see much ignorance or apathy here. I do see a lot of holier-than-thou stuff, which really takes away from the experience for me. Second, social media like Facebook is far too scattered for anyone to focus. Chat boards and forums on many topics are instead huge and growing. You know there are even boards for families of prisoners who need help? Facebook and Twitter would be the death of them if they had to rely on those, but their own forums keep things on topic and helpful. Link to comment Share on other sites More sharing options...

If they opened it up completely and drained all the water it wouldn't raise the lake even one millimeter. Other than that between Chapala and Salamanaca there are no dams. It is rain in the Lerma watershed that fills the lake. Link to comment Share on other sites More sharing options...
cedros Posted October 19, 2020 Author Report Share Posted October 19, 2020 in that people seem to know nothing about seiches on lakes. Nothing to do with holy -just facts https://www.nature.com/articles/s41598-019-48319-6. Someone post on here that the Conagua data was wrong because as he walked along the lake it looked high. Obviously a seiche. I spent my lat year at university studding Limnology and I see some really ignorant posts here about the lake. Link to comment Share on other sites More sharing options...

bmh Posted October 20, 2020 Report Share Posted October 20, 2020 The seiche would explain the changes in water lever in a particular area but it has nothng to do with the lake volume so I am missing something as well .. Link to comment Share on other sites More sharing options...
RickS Posted October 20, 2020 Report Share Posted October 20, 2020 Just as an aside.... "what" causes the lirio to 'suddenly' appear in large quantities in the lake? Where did/do they come from. I had always heard, possibly mistakenly, that it was a 'sure sign that they were letting water out of an upstream dam'. Link to comment Share on other sites More sharing options...

Where did/do they come from. I had always heard, possibly mistakenly, that it was a 'sure sign that they were letting water out of an upstream dam'. The Rio Lerma is a very slow flowing river because it passes through very flat land. It is clogged with lirio and water lettuce for miles upstream. Normally the current isn't fast enough to push vegetation into the lake. Also there is a lot of vegetation packed on the shallow eastern shore which is basically a marsh. In the summer the lake level rises thus freeing the vegetation from the marsh. There is more water in the river hence more current pushing vegetation into the lake. The winds come from the east pushing all of this into the lake. Link to comment Share on other sites More sharing options...
