Any homestead entryman under the Act of June seventeenth, nineteen hundred and two, known as the reclamation Act, including entrymen on ceded Indian lands, may, at any time after having complied with the provisions of law applicable to such lands as to residence reclamation, and cultivation, submit proof of such residence, reclamation, and cultivation, which proof, if found regular and satisfactory, shall entitle the entryman to a patent, and all purchasers of water-right certificates on reclamation projects shall be entitled to a final water-right certificate upon proof of the cultivation and reclamation of the land to which the certificate applies, to the extent required by the reclamation Act for homestead entrymen: Provided, That no such patent or final water-right certificate shall issue until after the payment of all sums due the United States on account of such land or water right at the time of the submission of proof entitling the homestead or desert-land entryman to such patent or the purchaser to such final water-right certificate.

Every patent and water-right certificate issued under this subchapter shall expressly reserve to the United States a prior lien on the land patented or for which water right is certified, together with all water rights appurtenant or belonging thereto, superior to all other liens, claims, or demands whatsoever for the payment of all sums due or to become due to the United States or its successors in control of the irrigation project in connection with such lands and water rights.

Upon default of payment of any amount so due title to the land shall pass to the United States free of all encumbrance, subject to the right of the defaulting debtor or any mortgagee, lien holder, judgment debtor, or subsequent purchaser to redeem the land within one year after the notice of such default shall have been given by payment of all moneys due, with 8 per centum interest and cost. And the United States, at its option, acting through the Secretary of the Interior, may cause land to be sold at any time after such failure to redeem, and from the proceeds of the sale there shall be paid into the reclamation fund all moneys due, with interest as herein provided, and costs. The balance of the proceeds, if any, shall be the property of the defaulting debtor or his assignee: Provided, That in case of sale after failure to redeem under this section the United States shall be authorized to bid in such land at not more than the amount in default, including interest and costs.

Upon full and final payment being made of all amounts due on account of the building and betterment charges to the United States or its successors in control of the project, the United States or its successors, as the case may be, shall issue upon request a certificate certifying that payment of the building and betterment charges in full has been made and that the lien upon the land has been so far satisfied and is no longer of any force or effect except the lien for annual charges for operation and maintenance.

No person shall at any one time or in any manner, except as hereinafter otherwise provided, acquire, own, or hold irrigable land for which entry or water-right application shall have been made under the said reclamation Act of June 17, 1902 and Acts supplementary thereto and amendatory thereof, before final payment in full of all installments of building and betterment charges shall have been made on account of such land in excess of one farm unit as fixed by the Secretary of the Interior as the limit of area per entry of public land or per single ownership of private land for which a water right may be purchased respectively, nor in any case in excess of one hundred and sixty acres, nor shall water be furnished under said Acts nor a water right sold or recognized for such excess; but any such excess land acquired by foreclosure or other process of law, by conveyance in satisfaction of mortgages, by inheritance, or by devise, may be held for five years and no longer after its acquisition, and water may be temporarily furnished during that time; and every excess holding prohibited as aforesaid shall be forfeited to the United States by proceedings instituted by the Attorney General for that purpose in any court of competent jurisdiction. The above provision shall be recited in every patent and water-right certificate issued by the United States under the provisions of this subchapter.

Jurisdiction of suits by the United States for the enforcement of the provisions of this subchapter is conferred on the United States district courts of the districts in which the lands are situated.

Any desert-land entryman whose desert-land entry has been embraced within the exterior limits of any land withdrawal or irrigation project under the Act of June 17, 1902, known as the reclamation Act, and who may have obtained a water supply for the land embraced in any such desert-land entry from the reclamation project by the purchase of a water-right certificate, may at any time after having complied with the provisions of the law applicable to such lands and upon proof of the cultivation and reclamation of the land to the extent required by the reclamation Act for homestead entrymen, submit proof of such compliance, which proof, if found regular and satisfactory, shall entitle the entryman to a patent and a final water-right certificate under the same terms and conditions as required of homestead entrymen under the Act entitled “An Act providing for patents on reclamation entries, and for other purposes, approved August ninth, nineteen hundred and twelve [43 U.S.C. 541 et seq.].” 1
