The fresh waters of the Colorado river reached the Gulf of California at high tide on Thursday, the first time in decades that the river has flowed all the way to the sea.

Wow! I didn’t know this … mostly due to the fact that I don’t live in Mexico,
but I do look at my wall map everyday that shows the Colorado River
flowing out of California and towards what looks like the Gulf of California.

The next you know they will tell me that the Rio Grande River doesn’t flow all the way to the Gulf of Mexico. Wait I already knew that lol

The Rio Grande stops 2 and 1/2 miles from the Gulf of Mexico with all of the water being used for agriculture by both countries.

I thought the Rio Grande issue was something that was temporary in the early 2000’s.

It says in the article that “a huge pulse of water” was released from a dam. I don’t mean to be a cynic, but is this anything other than a temporary “feel-good” measure? A pulse, by definition, is a transient phenomena.

Here’s an interesting quick read (PDF) about the Colorado from ‘source to sea’ by a couple of students that captured the trip in pictures and a brief report.

Good news.

Here is an article explaining the pulse. It says the pulse is supposed to last eight weeks.

That’s all well & good, but it sounds like after 8 weeks everything is going to go back to normal.

Rivers, especially in dry areas like much of the Colorado’s run, routinely have heavy floods. Damming the rivers has prevented this natural behavior.

The purpose of the pulse is to simulate such a flood. This does all sorts of nice things to the ecosystems along the banks of the river, replenishing sand bars, etc.

Being a pulse is a good thing.

I think this web page got it from the Wikipedia article on the Rio Grande, but I don’t like to go there.

“During the summer of 2001 a 100m wide sandbar formed at the mouth of the river, marking the first time in recorded history that the Rio Grande failed to empty into the Gulf of Mexico. The sandbar was subsequently dredged, but it re-formed almost immediately. Spring rains the following year flushed the re-formed sandbar out to sea, but it was back by summer 2002. Since then the sandbar has remained and now forms a usable land bridge between the US and Mexico. Ecologists fear that unless rainfall returns to normal levels during the next few years and strict water conservation measures are adopted by communities along the river, the Rio Grande may soon become extinct.”

I just learned about a year ago that the Colorado River I’ve been on my whole life in Texas is not the same Colorado River…

This might be the last time that this happens.
