This is one of the
flood incidents of 2024.
The dam is a long earth dam. This is a small fraction of the dam.
The dam is about 2.5 mile long. [

I thought the key word was "watch" in "potential failure watch." Perhaps they assigned extra workers to keep a close eye looking for problems, but they haven't found any problems.
But I was wrong. On Jun 28, they announced that the spillway "has been adversely impacted by the recent heavy rainfall and flooding in the dam’s drainage area.
" As of May 25, they said "there are no failures or problems at the Lake Livingston Dam.
" So, something happened between May 25 and Jun 28. It can safely pass 300 kcfs. [trinityra] But nobody is admitting what the "adverse impact" was.
The lake is 100% full. The capacity unit is thousand acre-feet.
This was back on Apr 29, 2024. This release caused major flooding downstream. Major flooding is the category of flooding that means that some homes were inundated.

A comparable view during normal river levels the year before. We can see the left side of the powerhouse in the police officer's video above. Note that the water is up to the "black line" that is about in the middle of the view below. I think all of the trees in this view are under water in the officers view.
When this TikTok video was produced, it was spilling 120 kcfs, which already broke the previous record set during Hurricane Harvey of 110 kcfs. Unfortunately, I can't find a date on this video. It looks like this was the late April flooding incident, not the damaged spillway watch incident of late June.
I can't find a date on Facebook reels either. That drives me nuts. I think this one also happened back in April. This is a good view of the hydraulic jumps.
This lake supplies 57% of Houston's daily water supply. The reporter asked what caused the alert, but he still hasn't received an answer. [2:02 video @

The powerhouse was evidently added later to the dam. I have not been able to find a date for that construction nor the megawatt capacity.
Update
The damage was erosion of the riprap by the wing walls and the destruction of part of the stilling basin wall.
The record outflow of 124kcfs was on May 2. Casey goes on in the video with a clear description of the damage. Or particular note, the riprap in the spilling basin was washed away and there was head cutting under "vast portions" of the spillway apron. Also, when he contacted the water authority on Jul 3, they would give him the same worthless PR info that was given to the press. But he says on Jul 4, they did release some info. He made this video on Jul 5.[8:19 video @

NBC had a video that was not at all related to the title of the article I accessed, but it was interesting for this dam. It looks like the repairs might be in a race against the rain that Hurricane Beryl could dump.

Some of the biggest waves I’ve seen! Lake Livingston, TX They had the bridge shut down because of waves coming over it! Outhouse Pitts: It was bad but the waves were coming over the bridge during hurricane Ike. Frank Evan Dick: Anyone know if the damn is holding up, a friend told me there was some decoration. He lives downstream and is already flooded some. Michael McCollom: Frank Evan Dick it probably did alright since the winds were actually blowing from the dam side to the lake. In Rita or Ike, the wind was blowing from North to South towards the dam. That caused extensive damage to the dam. The waves were easily 8-10’. |
