The pipe has a riser, top of riser is about a foot below spillway. I haven't measured down to bottom of riser elbow, I estimate riser is about 4 or 5 feet tall. The culvert I.D. is around 16", length is around 30 feet. On back side of dam it's about 7 or 8 feet from top of dam to bottom of pipe. Top of riser is in the face of the dam, basically a hole with a cage around it where water falls down into riser. Will try posting some photos
