Drew, sorry for your loss.
For the lowest profile ditch crossing, I have sunk twin wall pipe with the top of the pipe down to the level of the bottom of the ditch, mesh and round stones closing off the entrance and exit. The water flow in the ditch goes down into the ground at one side and back up at the other. A 6" pipe is more than enough for me, so your 12" should take a huge water flow, even with the ends slightly restricted this way. I guess that wouldn't work if you are wanting to provide shelter for homeless snakes and alligators.
