1957 Lake Arlington Dam and Pumping Station

Lake: (Satellite)
Dam: (Satellite, it has a morning glory spillway)
Pumping Station: (Satellite)

There are buildings between Pioneer Parkway and the dam so one can catch just glimpses of the earth dam. Using the scale on Google Map, the dam is right at a mile long.

The $21 million capital improvement project will deliver tap water for more than 500,000 residents across North Texas. The updated facility contains pumping operations for the City of Arlington and Trinity River Authority of Texas. The project consisted of removing and installing new pumps, electrical gear, and instrumentation. The pump station consists of six vertical turbine pumps. Three of them that will serve for City of Arlington, and the other three will serve for Trinity River Authority. All pumps are capable of running at the same time during peak demand. Two, separate 60-inch pipes feed water to each providers' water treatment facility. Improvements also included the expanding the electrical building to house all the new electrical gear and a containment structure for a new copper sulfate tank. The 10' diameter tank is capable of holding about 7,050 gallons. The copper sulfate is injected into the 60" discharge pipe in the pump station and wet well to combat zebra mussels.
[I knew the Great Lakes got zebra mussels from the ballast of ocean going ships. I wonder how this land locked lake got them.]

I presume this shows four of the six vertical turbine pumps.

[Is this road the concrete crest of the emergency spillway?]
At 550' it holds 38,800 acre-feet and at 564' it holds 70,900. [rating-curve]

The dam is on Village Creek. The creek was dry on most of the images on Google Earth. Here is the most recent with some water going through the morning glory spillway. Note the spillway in the lower-left corner.

And here is the wettest one I found.
