Great Images of Metro Stormwater Management
Check out the over 17,000 shots of the Twin Cities by the Metropolitan Design Center--including many good aerial shots of stormwater ponds (this link is to a slide-show), etc. I was sent this link by Ron Struss of the University of Minnesota Extension Service. He writes:

This site is loaded with excellent photographs of Twin Cities water resources, predominately aerial shots. It is supported with a basic search engine that allows you to locate photographs by Cities, Bodies of Water, Parks, Roads, Landmarks, Developments, and Structures. An advanced search engine allows for even more detailed searches. They also have pre-made slideshows - ones of interest are titled "Growth/Sprawl", "Impervious Surfaces" and "Stormwater". If you like a particular picture in a slide show, you can search by photo number to download a copy.

Here's a picture of the Minneapolis skyline behind Lake of the Isles, Cedar Lake, and the Cedar Lake constructed wetlands.
