Starcke Dam

"The dam is a concrete gravity structure of 860 feet long including the spillway, powerhouse, and other facilities....Spillway is controlled by 10 roof-weir floodgates, each 60 feet wide and 15 feet high."
[I was puzzled by the gates in the various photos. I'm going to have to figure out how roof-weir floodgates work.]

"Starcke Dam is the smallest in the Highland Lakes chain, and the last one completed."
Dimensions: 98.8 feet [30,] high, 859.5 feet [262m] long; generating capacity: 41.4mw; discharge capacity: 101,000cfs

July 4, 2025, Flood


On July 4, 2025, there was catastrophic flash flooding in Texas Hill Country. That rainstorm is working itself downstream.

LCRA opens floodgates at Wirtz and Starcke dams after Hill Country floods kill at least 13.
[The count was at least 43 deaths. (I saw an updated count of 78.[YouTube])]
"LCRA officials said they may need to open all 10 floodgates at Starcke Dam throughout the evening to move floodwaters downstream. The releases will flow from Wirtz Dam through Starcke Dam and into Lake Travis, creating fast-moving water and much higher than normal levels downstream."
"The Highland Lakes flood control system is designed to pass floodwaters through 'passthrough' lakes before capturing excess water in Lake Travis, the system's main flood control reservoir."

Avery Tomasco posted
The LCRA now says that all 10 floodgates may need to open overnight at Starcke Dam to pass flood water down to Lake Travis. 
That's a LOT of water moving through LBJ and Marble Falls. Lots of debris will be flowing quickly. I'd hold off on boating for the rest of the weekend.

[Several comments indicate that Lake Travis needs water. Texas has been having a serious drought.]

MWRD: More Water Aeration (including Centennial Fountain and Water Cannon) in Chicago

I have written notes on cities pumping a lot of water for purposes other than water supply: MWRD  pumps 1.3 billion gallons per day and Milwaukee used to pump 0.5 bgpd. These are more aeration facilities that I have discovered.

Centennial Fountain and Water Cannon

(many photosSatellite)

The night after I wrote the following, it occurred to me that the fountain recycles treated water, so it is not a Sidestream Elevated Pool Aeration (SEPA) Station. And I doubt the water cannon moves enough water to affect the dissolved oxygen levels. But I'm leaving it in these notes because I did a lot of work and because it is nice to see that MWRD can do something pretty, not just functional, with water.

In 1889, the Chicago Sanitary District was formed by the Illinois legislature to address the "river nuisance" in Chicago. In 1989, a successor organization, the Metropolitan Water Reclamation District (MWRD), built this Nicholas J. Melas Centennial Plaza and Fountain to commemorate its 100th anniversary. The water arc of the water cannon is 8 stories tall and shoots 80' out. [ConnectingTheWindyCity, other sources claim the arc is 90' long]

"Mr. Melas was first elected as a water district commissioner in 1962 and remained with the district for 30 years, serving as president for 18 years before leaving the post in 1992....The water district honored Mr. Melas by naming its Centennial Fountain after him. The fountain, on the north side of the Chicago River at McClurg Court, regularly shoots an arc of water across the river. In 1998, Mr. Melas began his 10 years as a member of the Illinois Pollution Control Board."

The cannon also obviously allows water to catch some air (oxygen). But it ran only 10 minutes each hour. And now it runs just five minutes because it was deemed a hazard to kayakers. It fires up on the hour for every hour between 10 and midnight except for 4pm. [LoopNorth] (Note the kayakers in the photo below.)

July 4, 2025 Flash Floods in Texas, at least 80+13 Fatalities

San Antonio had 13 deaths and Texas Hill Country has at least 43 deaths. Texas Hill Country is the Guadalupe River in a steep valley west of Austin, TX. The area was suffering from a serious drought, but they did not need 6-12" of rain in 1-2 hours starting at 4am. Hunt and Kerrville were hit hard by the tidal wave of water that came down the river while people were sleeping. In Kerrville, the river rose 30' (9m) in 45 minutes. Of note is the Christion all-girls Camp Mystic because, of the 400 campers, 23 were reported missing after the water swept through the camp.

Meteorologist Chris Vickers posted
I have no words. 
Here is what the Guadalupe river in Kerrville, TX normally looks like vs Fourth of July morning after catastrophic and deadly flash flooding. The river rose 23 FEET in just over 2 hours in Kerrville overnight. The river was less than 1 foot last night (0.3 feet) and soared with a torrent of raging water to 23.4 feet by morning. Heartbreaking to hear 13 confirmed fatalities and over 20 still unaccounted for -- many children, young girls feared swept away by flood waters at Camp Mystic on the Guadalupe river.  
Prayers that many of the missing may still be found safe! 🙏

Patty Gonzalez commented on Chris' post
Patty Gonzalez: This was the river just last week. Bone dry. I was there visiting family and we were walking the river bed. I’m praying my uncle‘s house doesn’t get flooded.

Chris' photo shows that the river was close to touching the bottom of the TX-16 Bridge that is in the background of this view of Louise Hays Park. Obviously, most, if not all, of the park was under water.

Needless to say, this celebration was cancelled because during the morning of July 4, that pavilion was under water.

This reel contains a time lapse of the water rising to swallow that pavilion. Fortunately, it would have been designed to withstand floods and probably just needs a good pressure washing.

This reel provides the river level information. The river had been less than 20cfs. Would that even get your shoes wet?

As I mentioned, and Patty's photo above illustrates, the area had been suffering a serious drought. (I'm avoiding the official terms of severe and extreme because different places in this area had different levels of serious drought.) The good news is that the reservoir lakes are low, and they should be able to handle the rush of water. The bad news is that the drought has dried out and backed the soil so that it doesn't absorb the rainfall. This reel provides some information on the drought. I think Canyon Lake is the first one downstream of this deluge.

This reel summarizes the flood down in San Antonio, and I can skip all of the previous reels I saw about San Antonio.

The Llano River also received a lot of rain.

The rest of these notes are about the flooding along the Guadalupe River.


I really wished they had indicated which bridge this was taken from. And I wonder if the water later went over the bridge.

Later, he zoomed out and you could see that the water was close to the bottom of "this bridge." I determined that "this bridge" was the Veterans Memorial Highway Bridge. The houses in the video would be on the left side of this excerpt.

As the camera turned to the right, it appears that the water used to be on this side of a building near the bridge.

Judging by the debris on the bridge, this is after the river went down a few feet.

This is Centerpoint bridge right off of 27 which no one ever thought would flood after they built it much higher than the previous bridge!!

Another view of the debris on that bridge. It was up over the banks.

More OMGs. I think I would have turned off the windshield wipers. Note at the bottom of the screenshot that the water is up to the steering wheel.

The reporter in the following reel says that the owner said that there were 33 RVs and mobile homes parked in this facility, and they all got swept away.

That RV wrapped around the tree is from an upstream RV park.
There was no clue of a problem at 2:30, but at "3:30 they were hit by a 24' [7m] high wall of water."

Where I live, "air raid" sirens now mean a tornado warning. In Comfort, they mean you should evacuate because the river is rising.

I saw a few reels of this home floating downstream with people still inside. At the beginning of this video you can see people standing in the doorway.

Man, it is bad enough to watch cars float down a river, but to watch houses move is unreal.

It was daylight by the time the water reached Comfort, TX. I presume this view is from the I-10 Bridge.

It is a good thing that bridge is bluff-to-bluff over a large flood plain because it needed all of that height and breadth to pass the flood waters.

San Angelo also got hit hard even though both rivers through town have dams on the upstream side of town.

The above bridge caught my eye because the downstream river level is so much lower than the upstream level. The small opening in this view explains the difference between the water levels --- the "bridge" is effectively a dam.

The water level was the same in an Aug 2019 view, but we see more of the opening in this view.

I had noticed there were other camps close to rivers when I was looking for Camp Mystic: Camp Honey Creek For GirlsCamp Stewart For Boys and Camp La Junta. The floating cabin was from Camp La Junta.
In fact, there are 18 camps in the area. [reel]

They had at least 14 helicopters searching for people and rather soon at least one girl was pulled out of a tree.

But it took quite a bit longer to find these girls.
