Lake Level Falls

Recommended Posts

According to the Lake Chapala Weather Net the level of Lake Chapala has fallen.

On July 25th. the level of the lake was reported at 93.67 Meters.

On August 5th. the level of the lake was reported at 93.66 Meters.

This is not much but for the height of the rainy season it is troubling.

Isn't it well established fact that the lake level is not dependent on the rain, but rather on whether or not the farms and industries upstream open the dams as they are required to by law?

But only in an indirect fashion, because the more rain there is, the more likely the upstream dams will be opened, thereby doing the replenishing.

If you think the lack of water is troubling...in Chiapas I just got back from the Chenalhó area , a very poor area the people live off corn and beans and ge some cash from the coffee crop. The corn is now getting yellow and they say it will not grow properly so there will be hunger and the coffee crop is decimated because of a plague called roya, so no money to supplement the food..

The government is offereing plants to replants(next harvest in 5 years..) but people are afraid that the improved plants are robusta rather than arabica so they do not want to use the plants..

Meanwhile in the last 5 weeks we had crops destroyed by huge hail storms, one large earthuake and 4 tornadoes, one of them took off with part of my roof..

The drought is going to bring humger and more poverty in an area already very poor..

Also of importance to how much water flows down the Lerma is its watershed, mainly southern Guanajuato, northern Michoacan and eastern Jalisco. So, we need rain in those areas too.

As to the dams, my understanding is that the dam holders, all 500 or so of them, rarely let water flow past their dams (down to the next dam) as they should legally (as if that matters much in Mexico). The way water gets past the dams is to simply overflow them as it did in 2010 which brought the lake level up after years of very low level.

Yes, as Dr. Stong has said, the median amount of rainfall around the lake almost exactly equals evaporation. But, if we get more than that, of course, it will cause the lake level will to rise.
