The Everglades restoration effort is building momentum. Projects are finishing, new infrastructure is moving ahead and state and federal agencies are coordinating better. But the National Academies’ latest independent review says the program still lacks a reliable way to show which investments are producing which ecological results.
That gap matters. South Florida’s restoration is measured not only in construction milestones, but in whether water reaches the right places, at the right times and with the right quality to sustain wetlands, wildlife and coastal estuaries.
The National Academies’ Eleventh Biennial Review, completed in September and released Oct. 22, examines progress on the Comprehensive Everglades Restoration Plan, or CERP, during 2024–2026. Congress required periodic independent reviews when it authorized the plan in 2000. On Nov. 2, WGCU’s Tom Bayles summarized the findings.
The takeaway is a qualified one: restoration is moving faster, but a clearer, shared system for assessing outcomes is still needed.
Faster progress, with conditions attached
The National Academies report says record state and federal funding has accelerated CERP implementation. Seven projects or major components are complete, and four are fully operational. Monitoring has also recorded encouraging signs, including increased water flows and the return of wetland vegetation in some areas.
Those are meaningful advances, but they do not establish, by themselves, that the restoration is achieving all its intended ecological goals.
The report says momentum depends on continued funding and enough staff to manage permits, project reviews and requirements under the Endangered Species Act. Agencies should explain what happens if supplemental funding falls, the committee says. A construction schedule can move quickly while critical environmental reviews or ongoing operations remain constrained by staffing.
The 15-member committee includes doctoral-level experts in fields including ecology, hydrology, engineering, chemistry, statistics, economics and wildlife biology. Its central challenge to the agencies is straightforward: make it possible to assess results across projects and distinguish the effects of restoration from outside influences, including weather variability.
The accountability gap: activity is not the same as impact
The CERP agencies collect substantial monitoring data. The problem identified by the Academies is that those data do not yet consistently add up to a clear, program-wide account of outcomes.
A wetland may get more water after a project is completed. But was that change caused by the project, rainfall, another water-management decision or a combination of factors? Without stronger analysis, the report says, it can be difficult to know. That makes it harder for the public and Congress to judge whether a project is meeting its goals, and where management should change.
The Academies call for stronger monitoring, modeling and data analysis, along with clearer definitions of what success should look like under today’s conditions. They also urge better communication about trade-offs. Restoring flows for one part of the system can affect water levels, timing and needs elsewhere.
The original Everglades cannot be recreated as it was. As WGCU reported, about half of the historic ecosystem was lost to development and agriculture; what remains is roughly the size of New Jersey. That reality does not make restoration pointless. It means agencies need to be candid about achievable goals and show how progress toward them is measured.
A sparrow in need of emergency protection
The review’s most urgent wildlife warning concerns the endangered Cape Sable seaside sparrow. Water-management plans have not adequately protected the bird, according to the committee, which calls for emergency conservation measures, including moving birds to suitable habitat and accelerating captive breeding.
The recommendation signals a hard limit of relying on water infrastructure alone: rebuilding hydrology may not be enough to protect every species facing immediate risks. The committee says managers need to consider additional interventions alongside restoration projects.
Water quality remains another major challenge. WGCU’s account of the review says nutrient pollution limits are not being met, while the Academies flag risks around phosphorus and the potential for changing flows and canal-to-marsh interactions to mobilize it.
There is an important regulatory distinction. The South Florida Water Management District’s latest STA update says the current Water Quality Based Effluent Limit took effect May 1, 2026, and that no Stormwater Treatment Area is currently out of compliance. The district’s update reports that in Water Year 2026, four of five treatment areas recorded annual phosphorus concentrations at or below 19 parts per billion, while one reached 13 ppb. Those figures describe treatment-area performance; they should not be mistaken for proof that the broader Everglades nutrient problem is solved, or for a finding of current regulatory noncompliance.
The South Florida Water Management District says Stormwater Treatment Areas are designed to reduce nutrient pollution before water enters the Everglades.
Lake Okeechobee puts the system in sharp focus
The lake’s latest numbers offer a real-time reminder of why timing and measurement matter. The U.S. Army Corps of Engineers’ preliminary report ending Nov. 2 put Lake Okeechobee at 13.39 feet, up 0.37 feet from the previous day and still below the 1965–2007 period-of-record average of 15.03 feet. The same report recorded inflows of 22,011 cubic feet per second.
The outflow figures require care. The lake report says it could not calculate a total outflow because data for S-77 or S-308 were missing; it lists S-77 flow at zero. A separate Corps daily-status update lists 186 cfs in total outflow. These are different preliminary reporting products, and the available reports do not reconcile the difference. The 186-cfs figure should not be presented as a confirmed direct release through S-77.
Meanwhile, the Palm Beach Post reported that record El Niño-season rain could force substantial releases toward the St. Lucie and Caloosahatchee estuaries in coming months. That is a concern about what may become necessary, not evidence that major lake releases are already occurring.
As of Nov. 3, the National Hurricane Center reported no active Atlantic tropical cyclone; a western Atlantic low had a 10% chance of subtropical development in 48 hours and 30% in seven days, with no Florida threat. The rainfall is non-tropical.
The EAA reservoir: a project milestone, not proof of results
The Everglades Agricultural Area A-2 Reservoir illustrates the difference between construction progress and demonstrated ecological outcomes. The project is a major part of the wider restoration plan, designed to store water south of Lake Okeechobee and support flows toward the Everglades.
The Corps’ initial-fill comment window closed Monday night, Nov. 2. That process concerned planning how the reservoir would be filled safely; it was not a start date for filling. The South Florida Water Management District’s project page describes the reservoir as a 10,500-acre project, with construction accelerated toward a 2029 completion target.
That makes the project a useful example of what the Academies’ scorecard does, and does not, measure. A reservoir advancing through construction is evidence of implementation pace. Whether it delivers the intended water-quality and ecological benefits will require ongoing monitoring and clear reporting after operations begin.
What the scorecard says
The latest review does not dismiss progress. It documents faster implementation, completed work and encouraging early signals. But the report also makes clear that a list of projects is not enough to establish what is working across the whole Everglades.
The next test is whether agencies can sustain funding and staffing, protect species such as the Cape Sable seaside sparrow, address nutrient pollution, and publish a more coherent account of results, including where outcomes fall short and why.
For South Florida residents, the key question is not simply how many projects are built. It is whether the restored system is becoming healthier, and whether the evidence is strong enough to show it.
