Title 43 › CHAPTER 12 — RECLAMATION AND IRRIGATION OF LANDS BY FEDERAL GOVERNMENT › SUBCHAPTER I — GENERAL PROVISIONS › § 390
Starting December 22, 1944, if the Secretary of the Army, after the Secretary of the Interior recommends it, finds that an Army‑operated dam or reservoir can be used for irrigation, the Secretary of the Interior may build, operate, and maintain extra irrigation works under the Federal reclamation laws (Act of June 17, 1902). Those irrigation works can only begin after the Interior Secretary files the required report and findings under those reclamation laws and after Congress gives specific approval. The report can assign part of the cost of shared structures to irrigation as long as water users can repay their share. This does not change lawful uses already in place and does not apply to Army projects already built that provide irrigation storage. For reservoirs the Corps of Engineers built or runs, the Secretary of the Army may temporarily use water set aside for municipal and industrial supply (if it is not under contract) for irrigation for reasonable periods until it is needed for those supplies. Any interim contracts for that water must not significantly affect existing uses.
