Yeah, no mortar. I think there had to have been mortar at some point, but this thing is likely 50+ years old and the mortar probably eroded.

Under normal conditions, water comes out the bottom of the dam in a trickle, not too bad but it does seem to have a noticeable effect on the pond level during dry summer months.

I think we do need to save the pond. It’s right in front of our house and thus is a major part of the view from the house. Plus, my wife has fallen in love with the koi in the pond…

Moments like this make me want to move back to the city!
