Title 16 › CHAPTER 5A — PROTECTION AND CONSERVATION OF WILDLIFE › SUBCHAPTER I — GAME, FUR-BEARING ANIMALS, AND FISH › § 662
Federal agencies must talk with the U.S. Fish and Wildlife Service and the state wildlife agency before they build or change dams, divert water, deepen channels, or otherwise alter streams or other bodies of water for any reason. The Interior Department and the state must do surveys and give specific reports about how the project could hurt wildlife and what steps would prevent or fix the harm and help wildlife improve. Federal project reports to Congress or to officials who approve projects must include and consider those recommendations and add reasonable wildlife measures to the plans. Money to plan, build, or maintain those wildlife measures counts as part of the project cost, but only for land buys, specific facilities recommended in reports, project changes, and changes in operations — not for running wildlife facilities. Federal builders can give funds to the Fish and Wildlife Service to carry out investigations. Project reports must estimate wildlife benefits or losses, the costs for wildlife measures, how much of joint facilities is for wildlife, and any part to be repaid by non-Federal parties. The rules apply to projects authorized before or after the law unless a project is already substantially completed (60% or more of estimated construction cost obligated). The rules do not apply to impoundments smaller than 10 acres or to federal land-management programs on federal lands.
