Yes, you could be right.
It is either Moncisco or Gallegos, it seems to me.
According to literature I've been able to find on line, Gallegos was to feed the "Burnham Lateral Canal," and Monciso was to feed "Burnham Lateral Stage II."
The NIIS is divided into blocks. You can see the blocks quite clearly in the Google map image of the area.
There are three groups of center-pivot irrigation farms. The western one contains blocks 1, 2, 3, 6, 7 and 8. The (large) north-eastern one contains blocks 4 and 5.
The small one that's south of the pumping station is Block 9. There are to be two more large blocks - Block 10 and Block 11 - still farther south of Block 9. These will be fed by the "Burnham Lateral Stage II," which is to receive water from the Moncisco pumping station.
This is why I think the one I was asking about is Gallegos.
The map I'm referring to is on page 6 of this document.
I think you’re right. That’s a good map.
