Hi There,

I don't believe that is a drainage system.  Instead it is a catch water ferrying rain water from the western slopes towards reservoirs.  I think I know where the photo was showing.  It seemed to be where the catch water cross Route TWSK just a bit lower than the hair-pin turn.  The catch water system is still in use today.

Thanks T. The same area is shown in another photo from that article:

I couldn't understand why they went to the trouble of building those "road bridges" in the lower photo, if they wouldn't be used. But it makes sense that they're part of the catchwater system instead.
