Lake Chapala - Extrapolated Lake Levels For 2019 Rainy Season

Just looking at where Lake Chapala water levels might be after the rainy season this year based on a couple of assumptions.

Assumption 1:
The water level follows the 2017 rainy season trend from this day forward.
In mid October the lake will peak .47 meters (18.5 inches) higher than the highest point this year.

Assumption 2:
The water level follows the 2018 rainy season trend from this day forward.
In late November the lake will peak 1.62 meters (63.8 inches) higher than the highest point this year.

Lake Chapala water

Interesting

If scenario two transpires that will put the bottom the the N/S streets in Ajijic underwater. It will be at the very top of the malecon.

Well Maria Isabela Restaurant was 3 feet underwater back in the 70's so I suppose it can happen again.

One of the members here said you had to wade through pretty high water to get a beer...but of course, they did.

It was slainte39 and I'm sure he would crawl 100 meters on crushed glass to get a beer...…..

I think it would depend on the beer.

It made me go take swimming lessons. with a reward    
There´s an old Irish saying or joke of "why learn how to swim?, it just takes longer to drown/die if your boat goes down."

Seriously, the high water back then caused a lot of damage to properties all around the lake, so they dredged and excavated the source of the Rio Santiago at Ocotlán to lower the level of outflow.  Since the the lake hasn´t reached that level in years i would imagine that sediment and silt would have to be dealt with again as those lirio roots impede and hold a lot that would have cleaned out naturally by a constant flow of water, which hasn´t happened in a long time.

Agreed. Those that are down on the lakefront or needing those lower roads to access their property better be thinking of solutions because that second scenario detailed above is a high probability.

I'm guessing the local people that erect all the temporary cabanas along the lake shore in Ajijic for the Semana Santa (Easter, April 14-20?) celebrations might be a little short on space this year!  Maybe the lake will have receded enough for them to camp out?  I think it's getting close to the time when they start claiming the best locations with a few bamboo poles...

The lake has receded about 14" from looking at the water mark in the skate bowl. I doubt it will recede enough to expose that lower field by Easter unless we get an extraordinarily warm March. Even then it will be quite muddy and wet.

We're in an El Niño weather pattern this year. While these are inherently difficult to predict, the normal pattern for central Mexico is cooler/wetter winter (which we just had) and a warmer, drier summer. So we have that going for us. Neither 2017 or 2018 were El Niño years.

Cincy's chart above is still bang on his prediction. If so, we can expect the first significant rise sometime between the end of June and mid July. I believe July 1 is when the upriver dams are now mandated to release their first load. Will be an interesting year. As we all know the local rain doesn't add a whole lot, its what they get further inland that really matters.

I sure hope all the dams up stream are not full and do not release at the same time like they did in Chiapas, it put Villahermosa under water when the water from the overflowing dams was let go a few years ago.. It is like a grand staircase all ending up in Tabasco that is flat as a pancake and full of swamp to start with...

I am sure happy the home insurrance includes flooding..

There is a preemptive solution and that is to dredge the outflow part of the Santiago River. Probably hasn't been done since the flood of 76'. I understand that is how they solved it then.

I also believe that the lake has not been dropping as much the past 3 years or so because they did fix the leaks and have built extra reservoirs in Guadalajara. They are not taking nearly as much as they used too IMO.

yes but dredging ahead of a problem is just not done , it is so much better to wait for a problem and resolve it too late...

And that is pretty much what the director of ConAgua told Dale when she asked them about it. I had posted all of it in the other Lake Level thread.

I think I am getting very good at figuring out the logic here.. never think one inch ahead , live in the present ,do not worry and do very little afterwards.. If you bought or live in an area that can flood your problem, same when the mountain goes down and the authorities who could have prevented just blame the people who built or lived there.. Asi es..

Tis true I suppose. Same could be said to anyone owning waterfront or mountain bottem anywhere in the world. Shit tends to happen every so often with floods, storms and landslides.

Yes but f flood is available by some dredging many countries will dredge before a problem rather than after...

You have that one right : Many of the front lake properties belong to well off tapatios. it will be interesting to see what their position will be. Hopefully they will not want to be flooded and we will see if they use their influence or not. We are not on the lake but we are not that far from it so I am very interested in the subject.
