These are the structures 6A, exit gates from the Pinto Pressure pipes. Water coming from behind these gates had just passed under Pinto Creek.
and was continuing downstream to the right in the next open air section of the canal. The photo on the left was taken in 1984
and the one on the right in 2011. Note that in the more recent photo are not only the gate lifting mechanisms missing but the concrete block
to the left that is embossed with "USRS 1905" is gone!!
