Winning in every conceivable way - China blows up 300 dams, shuts hydropower stations to save Yangtze River habitat (www.scmp.com)

China has demolished 300 dams and shut down most of the small hydropower stations on a major tributary of the upper Yangtze River to safeguard fish populations as part of an effort to restore the ecology of Asia’s longest waterway.

According to a report by the state news agency Xinhua on Monday, 300 of the 357 dams on Chishui He – also known as the Red River – had been dismantled by the end of December 2024. In addition, 342 out of 373 small hydropower stations have been decommissioned, enabling many rare fish species to resume their natural reproductive cycles, the Xinhua report said.

The Red River flows for more than 400km (249 miles) through the southwestern provinces of Yunnan, Guizhou and Sichuan. It is regarded by ecologists as the last refuge for rare and endemic fish species in the Yangtze’s upper reaches.

Over the decades, water flows have been increasingly blocked by the dense network of hydropower stations and dams, restricting water volumes downstream and occasionally even causing some sections to dry up entirely.

This has drastically reduced the amount of suitable habitat and spawning grounds. The stations also blocked the routes of migratory fish species between breeding grounds and non-breeding areas.

What exactly do you think I’m asking about here?

A proposed dam literally the size of the entire subcontinent?

[–] bort@hexbear.net 14 points 1 week ago (10 children)

Why would a dam displace hundreds of millions of people?

Water still passes through them even if it’s slightly reduced while they fill. It’s not like the rivers in India suddenly dry up.

Hundreds of millions certainly seems like a stretch but dams displace people when there's suddenly a 300' lake in valleys where people lived.

Not sure of the specifics of this project but it's one of the major drawbacks of large scale hydro, it was a big problem with the TVA dams in America. Old crow medicine show has a song about it called "half mile down".

I found a YouTube link in your comment. Here are links to the same video on alternative frontends that protect your privacy:

Obviously the bot won't reply to this but is there an easy way to post one of those links in the first place?

[–] blobjim@hexbear.net 4 points 1 week ago (1 children)

You can just replace the domain name "youtube.com" with one of those domains. They all use the same format as the official youtube URLs.
