The Rio Grande around Espanola NM barely flows enough to float an innertube or raft. Maybe during melt-off season it cascades pretty deeply, but by Summer you can walk most of it barely knee deep.

NM is pretty bleak agriculturally speaking. Large cattle ranches go very cheaply outside of the tourist and town areas because it takes 50 acres or many times more to support one cow. Southern NM has best growing season. Eastern Colorado is good for agriculture, OK, KS, Neb but get into the Rockies and you lose soil and growing season. Pretty cold at night at any elevation much over 3000'. NM is a bleak place to live and worse to choose deliberately for survivalist relocation.

Eastern OK, AR, TN, Southern Missouri, Eastern TX, Louisiana and the rest of the South are best choices for climate, growing season, soils, water, and hardwood timber resources. With 5 or 10 acres in E. TX you could raise a cow or two, an acre of food crops, have some timber for firewood and likely find water fairly close to surface. Those kind of assets make making a life possible if you work at it and have enough gear to get established.
