Bill D.,
I am about 7 miles NE of El Paso. Just south of the Windmills.
In regard to water supply, I built it as deep as I could with funds available and with pretty steep banks realizing that in times of extreme drought it will essentially be a bathtub. Going to aerate as well. That said, we have a fairly high watertable out here so it will have to be a pretty bad drought. All the ponds out in my area were down in 2012, but most were at least 2/3 full still. Lots of blue clay out in these parts
