There's actually an inverted siphon here in Winnipeg. It's used to allow the Seine River to pass UNDER the red river floodway: http://maps.google.com/maps?f=q&source=s_q&hl=en&q=Seine+river,+Tach%C3%A9,+Division+No.+2,+Manitoba+R0A+0X0,+Canada&sll=37.0625,-95.677068&sspn=43.664131,78.310547&ie=UTF8&cd=1&geocode=FQj69QId6_85-g&split=0&hq=&hnear=Seine+river,+Tach%C3%A9,+Division+No.+2,+Manitoba+R0A+0X0,+Canada&ll=49.79002,-97.047815&spn=0.017455,0.038238&t=h&z=15 The meandering river in the middle of the frame seems to dissapear and reappear in the middle of the frame. In reality the river flows into a concrete box, under the floodway, and then comes up and out the other side.
