The junior Meigs is best known for his management of the
canal and
locks at the
Des Moines Rapids, as well his involvement in the construction of the dam at the same which inundated the canal. Although Meigs had not served in the military, he was often referred to as "Major" out of courtesy, because his predecessor at the Des Moines Rapids had been an army officer. Meigs' design for traffic control at the canal and locks prompted Captain F.A. Whitney to tell the
Saturday Evening Post in 1924 that he could not recall a single incident having occurred by any vessel passing through the locks, so long as the rules had been obeyed, and that Meigs did not hesitate to become involved personally if needs be. ==Other interests and skills==
