Almost directly opposite, on the right, is an irregularity. If that is sandbags it's unusual placement, isolated as it is. Also, it appears to be part of a "herringbone crack"
These two are the areas I'm concerned about.
Oh, I see - yeah, there’s a little trickle from a couple of weep holes on the left. I thought you were referring to the rows of sandbags way up near the top of the spillway, directing water to the right. I’m not in a good position to describe the details of what you’re noticing.
