Aqueducto matter - just the science please
Posted 23 April 2012 - 09:17 PM
Here are my questions:
How can the new aqueduct help the lake? Can it be a catalyst to improve the water situation in the wider area (for Guad and for Chapala)? How could the new 2nd aqueduct cause a deterioration in Lake Chapala water quality and/or life quality issues around the lake?

Removing water from the Lake is obviously not coming to help the lake. The question is - how much would be removed. Some say a minimal amount - so that the impact would be very minor.
The issue here, from my perspective, is the integrity of SIAPA. And it appears not very many people trust them.
You asked if it can be a catalyst to improve the water situation............ From my perspective, to improve the water situation, you need a competent government group to come up with a competent and comprehensive strategy. And the players are not in place to do that. Right now, Guadalajara doesn't even manage groundwater/aquifers - and that usage needs to be a significant part of any plan to improve the water situation.
You asked how that would cause a deterioration in the lake. The lake is about 45 miles long - and subject to the polices and practices of two states and multiple municipalities. Those interests are usually self serving - and not necessarily for the health of the lake. And you need to define what constitutes a healthy lake - as for me it includes a healthy ecosystem, and for water quality, you need to define exactly what you mean by water quality. From my perspective, those answers are best found in peer reviewed scientific documents - and there are many - mostly in spanish. One credible one indicates that there are a number of toxic chemicals in the sediment. I don't know that anyone has really researched everything that has been published. Other local studies have been initiated - but so far I don't think any have been peer reviewed.
And I guess my final comments are - is there any reason for SIAPA to change its practices. I can't think of any. So sooner or later the second aqueduct will be built. There will not be any strategy so this will be a short term solution. And there is no clear cut answer on water quality - again - a 45 mile lake managed by multiple political environments that probably have more immediate priorities.

Given, of course, the integrity and values of the regulators, authorities, etc.

Seems to me discouraging citizens from protesting the current management system of the lake is counter to what every resident wants and needs in the long run. This lake won't be managed as anything but a water source for agriculture and cities unless the citizens demand government conserve it for future generations...

Guad gets only a small percentage of it's water from Lake Chapala.
Atlas, most information sources I have seen say that Guadalajara gets between 60-70% of its water from the lake. What are your sources?
