some think abandoned windmills are a problem to dismantle and dispose of

what's the cost of removing a dam?

Depends on the dam. What's it made of? To remove one, you have to build diversions. You can't have a failure during demo or you would cause a catastrophe. I've done a number of dam failure analyses during my career. I don't think there is a worse flood possible, except maybe a massive storm surge like we had with Katrina. 

But, that was man-made too, of course.

If it has a spillway, the water level could be lowered hopefully substantially over time and left open.  But the bottom of the spillway could be fairly high relative to dam height.

It's a dam problem.

I imagine removal is costly and no one has the funds.

They all have spillways, but this one just overtops. A diversion would be necessary.

And then there is a lot of sediment behind the dam too, so finding a place to put that could be problematic. No doubt there is contamination.

There is nothing good about dams.

Some dams do confer some advantages.  Whether they outweigh the negatives is another story.

We had snow showers in the forecast, but I didn't see any, no stick of course.  This is our first night below freezing, 27°F.  It's up to 30°F now.

No wind, no clouds, sunny day, not bad at all really.

Absolutely beautiful snowfall overnight.  Looks awesome out.  Great day for a fire and some cocoa.  Though snow days ain't what they used to be for the kids.

My buddy in Cincy is sending me photos of the snow there.

I'd be fine with one or two a year, which is about what we get here, and it doesn't last of course.  Old snow is irksome.

After removal of the dams of the Elwha River, the fish are back with a vengeance.

I love stealing logs and sticks from Beaver lodges for shorelunch fuel.   Just doing my part to bring an end to dams.
