Pipeline Shapes

This is a continuation of my Adirondack Industrial photos.  While looking for some waterfalls (which we never did find, come to think of it), we turned down a side road and ran into this enormous pipeline.  D thought it was transporting water from a reservoir for power generation, and although he told me the reservoir, I can't remember the name.  I just thought it was incredibly cool... and incredibly enormous.  Here are my favorite shots of it.

First, for scale, here's a picture my husband took of me on top of it.  I'm relatively certain I shouldn't have been up there, but it was all for the sake of art...  When on top of it like that, I could feel the vibrations of the water rushing through the line.

Here it is, stretching into the trees.  It reminds me of a giant blue caterpillar:

I love all the details of the rivets and rust.

One lowly bee, perhaps trying to warm herself in the weak sun?

It looked to us like this old wooden water tower was at the end of the line, but how it's used is a bit of a mystery.  I could make several guesses, but have no real information to go off.  Anyone know the history of this pipeline?  This is my husband's shot of the tower, as it came out better than any I took of it.  I can't imagine there are too many wooden water towers still in use.
