Interesting. My Dad was the District Construction Engineer for District 5 which included much of the area around C-U. He always said he would take his newly graduated engineers to the area and ask them to make a drainage diagram for the area.....in which there was not a 3 ft. change in elevation within 50 miles. It was an unsolvable problem. Of course, there is a hill near Philo that makes that untrue. Yet, I doubt there is a 3 ft. change in elevation anywhere on the Illinois campus....so no sympathy from me.
