It's very interesting. The water can't move of it's own accord to the river, so every little way there are lift pumps that help it along. I saw something similar on the Rhine as a young lad.

So, how do these pumps work?

EDIT- Read comment.

So, you can't actually see the pump in action without crawling up the intakes or opening those doors. They would be awesome to check out, but I agree on the danger... no one wants to get cut in half.

Yep. All the pictures I really have of these things are located at http://www.basementfreaks.org/galleries/lift_station_7/

I'll try to go take a few more and figure out exactly how this sucker works some day. It's probably some type of pump that can pass solid objects without too much trouble, or else everything smaller than a tennis ball would go right through the grate and plug it up.

They do the same on the Mississippi. The bluff is 100 feet above river level, but the bottoms are right at flood level, as you would expect. They built levees along the river, so that the floodplains wouldn't flood (dumb, but it's really good soil). When the river is low, water can flow through creeks down the bluff, over the flood plain, through a flood gate and into the river. However, when the river is higher, they close the gate and have to pump the water over it. So there are pumping stations every so often.

Here's imagery on one at latitude 40.89627, longitude -91.02626.

Interesting. This is in Iowa? or MN? Someone ought to take a few pictures if they ever come upon one.

South-east Iowa, where I'm from. The further upstream you get, the higher the bluffs and smaller the flood plain, so levees (and big ditches and pump stations) become unnecessary.

I never bothered taking any pictures, because it was just part of the landscape. I will the next time I'm at my parents' house.


Near there, at lat 41.02310 lon -91.00600 there's a bridge across the big ditch, which I climbed. It's a two lane bridge on a gravel road, so it wasn't huge. But I hesitate with heights, and I did it free climbing barefoot, right after a thunderstorm. You can see the shadow of the trusses on the dry bed of the ditch next to the red dot. You can also see where they used imagery from two diferent passes on the right third.
