It functions because the rim is lower than the top of the dam and water is released with no human intervention. In short, in an emergency, the lake overflows beginning at the emergency spillway instead of the dam itself.

OK, I see it now. It is very hard to see with the aerial photos that the area in question is anything other than a concrete wall.
It seems most of these dams are not being kept up. The dam/levees in the area around here are also at risk and they were concerned about a breech last year, when the level was the highest it had ever been.
They say our issue is over development. But our red-clay ground is not porous. It was simply a HUGE rain event.
