Summary

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.

Any entryman on an unpatented farm unit on a Federal irrigation project which shall be found by the Secretary of the Interior, pursuant to a land classification, to be insufficient to support a family shall be entitled, upon timely application to the Secretary to exchange his farm unit for another farm unit of unentered public land within the same or any other such project, or, upon terms and conditions satisfactory to the Secretary, for any other available farm unit on the same or any other such project. He shall be given credit under the homestead laws for residence, improvement, and cultivation made or performed upon the original entry, and if satisfactory final proof of residence, improvement, and cultivation has been made on the original entry it shall not be necessary to submit such proof upon the lieu entry. Rights under this subchapter shall not be assignable.
