Oooo. An opportunity to get free opinion(s)!!! I just uploaded a couple of
files to PigHabit-L in the folder "Dam" (duh):

So whaddyathinkwhaddyathink? Some mortar on the embankment walls here and
there. Could be later repairs. Can't get close to the masonry under the
spillway until they divert the water. If no masonry, any speculation about a
concrete core (ca. 1895) even though generally understood to be a simple
earthen dam? (No investigation of the core yet).
