Restoring Hetch Hetchy

Grab your bear can or camp chair, kick your feet up and chew the fat about anything Sierra Nevada related that doesn't quite fit in any of the other forums. Within reason, (and the HST rules and guidelines) this is also an anything goes forum. Tell stories, discuss wilderness issues, music, or whatever else the High Sierra stirs up in your mind.

Sounds like a bad idea to me. Cut off your nose to spite yourface.

figured I'd bump this thread with a pointer to the Condit dam removal project, which just blew up on 10/26/11. Check out the video.. Now, obviously, they wouldn't do such a move on Hetch Hetchy because, well, this is California (read that how you want!).

I was most interested in how they got approval to blow it, given the amount of silt that'll move down stream, but.. Downstream it did move.

The northwest is an interesting place to look to for dam removal. Here is a couple of before and after from the Rogue River, my home:
Savage Rapids before:

Savage Rapids' turbines ran irrigation pumps and shredded salmon. Turned out that it was cheaper to run the irrigation pumps with electricity than water power. Dam came down.

Gold Rey had been out of action since the 70's and was also a fish obtacle. It was probably the last rope pulley generator in the US. I remember seeing it in operation as a teenager. Dam is also down.
