Independently verified. Mast has led on the EAA Reservoir for nearly a decade: he introduced the Everglades FIRST (Flow Increases Rely on Storage and Treatment) Act in May 2017, which explicitly directs the Army Corps to expedite the EAA Storage Reservoir and related CERP projects, and he has repeatedly driven Everglades appropriations (member-day remarks, bipartisan letters, the FY2026 $461M Energy & Water package). In April 2026 he appeared at the announcement (with Gov. DeSantis and the Army Corps) of more than $2 billion in federal funding executing all contracts to complete the EAA Reservoir by 2029 — five years ahead of the original 2034 timeline — so Lake Okeechobee water is stored and sent south rather than discharged to the coasts. This is far beyond a single supporting vote (sustained sponsorship + leadership), which meets CHAMPIONED. It is not FULL because the reservoir is not yet physically complete (targeted 2029). The fairness test holds: a member of either party with a decade of named-bill sponsorship, repeated appropriations pushes, and presence at the funding milestone would earn CHAMPIONED.
