Section 1. Short title

This Act may be cited as the Lower Yellowstone River Native Fish Conservation Act.

Section 2. Findings

Congress finds that—

(1) the Lower Yellowstone Fish Bypass Channel—

(A) was authorized under section 3109 of the Water Resources Development Act of 2007 (Public Law 110–114; 121 Stat. 1135) as a Federal mitigation measure for impacts on the pallid sturgeon (Scaphirhynchus albus) under the Endangered Species Act of 1973 (16 U.S.C. 1531 et seq.);

(B) was designed and constructed by the Corps of Engineers and the Bureau of Reclamation using funds from the Missouri River Recovery Program and other Federal appropriations specifically allocated for ecosystem restoration and endangered species mitigation; and

(C) is located outside the physical and operational boundaries of the Lower Yellowstone Irrigation Project and the Lower Yellowstone Irrigation District;

(2) the Bureau of Reclamation retains sole ownership, operational jurisdiction, and maintenance responsibilities for the Lower Yellowstone Fish Bypass Channel and related infrastructure;

(3) the Lower Yellowstone Irrigation Project was federally authorized in 1904 under the Act of June 17, 1902 (32 Stat. 388, chapter 1093), to provide irrigation water to agricultural land in eastern Montana and western North Dakota;

(4) the Lower Yellowstone Irrigation District, established under Montana and North Dakota State laws, has never had ownership, operational responsibility, or maintenance obligations relating to the Lower Yellowstone Fish Bypass Channel;

(5) the Endangered Species Act of 1973 (16 U.S.C. 1531 et seq.) mandates Federal protection and recovery actions for listed species, including the pallid sturgeon (Scaphirhynchus albus);

(6) endangered species recovery, including construction of the Lower Yellowstone Fish Bypass Channel, is solely a Federal responsibility;

(7) the Bureau of Reclamation opted to construct the Lower Yellowstone Fish Bypass Channel to comply with the Endangered Species Act of 1973 (16 U.S.C. 1531 et seq.) because the Intake Diversion Dam is federally owned and operated, rather than owned or operated by the Lower Yellowstone Irrigation District or the Lower Yellowstone Irrigation Project;

(8) the Lower Yellowstone Irrigation District or the Lower Yellowstone Irrigation Project cannot and should not be burdened with financial or operational responsibility for a federally mandated environmental mitigation project;

(9) the Lower Yellowstone Fish Bypass Channel is legally separate and distinct from the Lower Yellowstone Irrigation Project and the Lower Yellowstone Irrigation District; and

(10) without legislative clarity, future administrative actions could inappropriately attempt to shift the burden of operations and maintenance costs of the Lower Yellowstone Fish Bypass Channel onto the Lower Yellowstone Irrigation District, which is a scenario that contradicts the original intent of the authorization for the Lower Yellowstone Fish Bypass Channel under the Water Resources Development Act of 2007 (Public Law 110–114; 121 Stat. 1041).

Section 3. Definitions

In this Act:

(1) Lower Yellowstone Fish Bypass Channel
