All three cited sources are reachable, support the outcome, and contain the quoted text verbatim. (1) govinfo.gov (PRIMARY) confirms H.R. 4094 / Public Law No. 118-169, Great Salt Lake Stewardship Act, approved December 23, 2024 — verifying enactment. (2) curtis.senate.gov (PRIMARY) contains the exact quote "Incorporates the Great Salt Lake into ongoing Colorado River conservation efforts." and frames the measure as a Curtis-sponsored bill. (3) TownLift (REPUTABLE_SECONDARY) confirms Curtis "introduced legislation aimed at protecting the Great Salt Lake, which was successfully passed by the U.S. House" and that the bill "would include the Great Salt Lake in the ongoing conservation initiatives within the Colorado River Water Conservation Program," and separately confirms unused Central Utah Act budget authority would fund conservation — matching the promise's "unused Utah funds" element. The CHAMPIONED bar (genuine leadership + full success) is satisfied: Curtis was the lead sponsor/introducer (two independent sources describe him introducing/sponsoring the bill, not merely voting), and the bill was enacted into law as Public Law 118-169. The bill's substance matches the promise precisely. The rating does not overstate the evidence.
