Welcome to Permies, Kody!
The first question should be "what do you want to grow?" because that will partly determine how much of a
swale you need to put in. Are you interested in pistachio nuts? They are quite suitable for the high desert, and you could either have one long swale with pistachio
trees in a row, or you could make individual catchments for each of them if you wanted to space them out.
Trees like pistachio, almond, mesquite, palo verde, and pomegranate are already fairly drought tolerant, so it will take less of a water catchment to make them thrive than it will for things like stone fruits and apples or pears. Do you want to try some citrus trees? They are possible in your area, if you give them some winter protection. Mulberry is another good desert tree, the fruits are tasty if you can get to them before the birds do, and the leaves are good fodder for animals.
Unless you are right on a seasonal watercourse, I'm not sure a pond would be a good idea. With the high rates of evaporation and the sodic soils in the area, you don't want to be creating an alkali lake bed where you intended to have a pond. How hard is your ground/city/well water? Your
local water utility should be able to give you that information.
