Crane Fly larva?
I'm not very familiar with these, but I also found one just like yours, although skinnier. Here are some others to look at: http://bugguide.net/node/view/267485/bgimage?from=24 I know they are aquatic for part of their lives and they breath through their rear-end (by sticking it out of the water), which is called the spiracular area and can be used to determine species. I believe our resident Crane Fly expert is Chen Young, so he may be able to tell you more. Hope that helps for now. :)

Here's a page that Chen often shares: http://iz.carnegiemnh.org/cranefly/introduction.htm#Larvae It mentions right at the top "larval habitats, which extend from aquatic to terrestrial." There are some neat (and creepy) spiracular area diagrams drawn by Chen himself towards the bottom of the page, too.
