The weir will go nowhere.
It rests on drilled piers that go more than 25 feet into the native rock.
The concern at the weir was errosion below its bottom near the main spillway.
That was the very first thing that was reinforced with the grout and rock.
The dam is not an issue; flooding and storm flow management is. This has actually been true all of the time, but there was great concern for more possible damage to the main spillway before the erosion was addressed.

The spillways are the issue. There are maintenance issues but more importantly design issues.
