Title 43 › CHAPTER 12 — RECLAMATION AND IRRIGATION OF LANDS BY FEDERAL GOVERNMENT › SUBCHAPTER VII — EXCHANGE AND AMENDMENT OF FARM UNITS › § 451
If a person holds a farm unit on a federal irrigation project that the Secretary of the Interior finds too small to support a family, that person can apply on time to swap that unit for another unclaimed public-land farm unit in the same or another project, or for another available farm unit elsewhere if the Secretary agrees to the terms. The person gets credit under the homestead laws for the time they lived on, improved, and farmed the original unit. If they already gave final proof of those facts for the first unit, they do not have to give that proof again for the new unit. The right to make these exchanges cannot be transferred or assigned to someone else.
