This is another shot of the gravity fed relift pump I came upon recently, just outside Stuttgart, Ark USA. Its about 3 feet wide, and is a PIPE, lying about 2 inches below the water level, in the canal, and is used to irrigate crops and fields on farms. As the water drops to a certain level, the pipe quits accepting water. It makes a HORRIBLE sucking noise, and is kinda scary! I nearly fell in one of these as a child. Taken 2013 with a SanyoVPC-E2100, straight from the camera.
