Everglades Agricultural Area Reservoir

Sending the water south

No project matters more to ending the toxic discharges on the Treasure Coast. Here is how the EAA Reservoir went from a fight on the House floor to construction running ahead of schedule.

The goal78 billion gallons of clean water, flowing south by 2029

Legislative action On the ground The goal

Phase One — Authorization

2018

May 29, 2018

A commitment to build, won in committee

Rep. Mast secured a commitment from Transportation & Infrastructure leadership to authorize the EAA Reservoir in 2018's water infrastructure development bill — and passed his own amendments to develop algae-filtration technology and re-evaluate the Lake Okeechobee discharge schedule.

Bicameral momentum

Mast worked with then-Sen. Marco Rubio and former Sen. Bill Nelson to draft language authorizing the reservoir, lining up support on the Senate side.

Oct. 10, 2018

Through Congress

The Water Resources Development Act — America's Water Infrastructure Act of 2018 — cleared Congress with the reservoir authorization intact and headed to the President's desk.

Signed into law

President Trump signed the bill (P.L. 115-270). For the first time, the EAA Reservoir — the single most important project for ending discharges to the St. Lucie — was federally authorized.

Phase Two — The Fight to Build

2019 – 2022

Oct. 23, 2019

Holding the Corps to the law

One year to the day after authorization, with the Army Corps behind on a required report, Mast and Rubio called the delays "simply unacceptable" and demanded the Corps stop stalling the project.

Clearing the "new start" roadblock

When the Corps tried to slow the project by labeling it a "new start," Mast secured language clarifying that no such designation was needed for construction to begin.

Prioritize and expedite — by law

WRDA 2022 carried Mast's report language directing the Army Corps to prioritize and expedite completion of the reservoir, alongside his $100M Northern Estuaries Restoration Plan.

Phase Three — Shovels in the Ground

2024 – 2026

January 2024 Milestone

The treatment marsh is finished

Florida completed the 6,500-acre stormwater treatment area beside the reservoir — the wetland that cleans the water before it heads south.

July 18, 2025 Milestone

Five years cut from the clock

A landmark agreement between Florida and the U.S. Army moved the reservoir's completion date from 2034 to 2029 by letting the state lead construction of key components.

Sept. 10, 2025 Milestone

Blue Shanty Flow Way breaks ground

Crews began removing ten miles of berm along the Tamiami Trail — the "last mile" that lets clean water flow south into Everglades National Park and Florida Bay.

The pumps that move the water

Groundbreaking on the inflow pump station — nine pumps built to move roughly 3 billion gallons of Lake Okeechobee water into the reservoir each day.

Every federal contract, executed

All federally funded contracts for the reservoir were finalized with more than $2 billion secured — locking in the accelerated, five-years-ahead schedule.

2029 The goal

Water flowing south

When complete, the reservoir will hold 78 billion gallons, clean it, and send it south — restoring natural flow and easing the toxic discharges that have battered the Treasure Coast for generations.

"That's the day one promise, and I intend to keep it. We will get the job done."
