Title 16 › CHAPTER 5A — PROTECTION AND CONSERVATION OF WILDLIFE › SUBCHAPTER I — GAME, FUR-BEARING ANIMALS, AND FISH › § 663
When a U.S. agency dams, diverts, deepens, or otherwise changes a stream or body of water for any reason, it must make sure the area and any nearby federal land or water it owns are used so wildlife and their habitats are protected and improved, as allowed under section 662. How those lands and waters are used must follow a plan agreed to by the agency doing the work, the Secretary of the Interior, and the head of the state wildlife agency. If the work helps state wildlife (not migratory birds), the state may manage the area without charging an administration fee. If the area helps the national migratory bird program, the Secretary of the Interior may manage it. Federal construction agencies can buy lands or water rights for wildlife needs when allowed by the Act and by reports under section 662, but they must tell Congress how much they plan to buy, and for some already-authorized projects they need Congress to approve new purchases. Lands bought for wildlife must keep that use and not be traded away in a way that defeats the purpose. Federal lands set aside for water projects and given for wildlife use are covered by this Act. Lands bought inside a national forest become part of that forest and follow laws tied to the Act of March 1, 1911, unless they are for the National Migratory Bird Management Program.
