What's in a Dam II?

Back down to the refuge again today, a nice sunny day, partially warm. I'm gearing up for Wednesday's lunar eclipse. I'm hoping to get out into the country, far away from any light pollution. Camping, actually. So that post won't be until the next day.

Anyway, this is looking into the base of the dam, the outlet from the lake (far end) under the dam and then out into the irrigation canal.
