We were both surprised by the intensity of the water flowing from the dam out into the Des Moines River. So I took a video:
I posted a few pictures of the dam on my Flickr Page.
The area below the dam has been turned into a campground. After our drive around that campground, we proceeded to check out the other two Army Corp of Engineer parks on Saylorville (there's a 4th, but it doesn't open for another week). There were lots of campers bundled up in sweatshirts....some huddled next to fires wearing stocking caps. I was happy that I was just out for a drive instead of actually camping this weekend. Brr. But we'll be back ;).
