Jacksonville’s lawns are wet, its sprinklers are mostly idle and cooler weather is approaching. Yet an appointed water-management board continues its “Extreme” restrictions while approving additional groundwater for growth and pursuing costly projects intended to offset future pumping.

It has been raining again in Jacksonville. Lawns are wet. Afternoon thunderstorms have returned. Many homeowners have little reason to run their irrigation systems because nature is already doing the job.

Soon, temperatures will fall. St. Augustine grass will grow more slowly and may enter winter dormancy. Residential irrigation demand will decline whether government orders it to or not.

Yet Jacksonville remains under a Phase III Extreme Water Shortage order limiting landscape irrigation to one day per week. The order increasingly tells people not to do something many are not doing anyway.

That raises a more important question than which day residents may turn on their sprinklers:

Is Phase III the St. Johns River Water Management District’s plan for repairing Northeast Florida’s water supply—or merely the most visible Band-Aid covering a much larger problem?

Watering restrictions can reduce discretionary demand. They cannot recharge an aquifer, construct an alternative supply or reconcile continued population growth with a groundwater source the district already says cannot safely meet projected demand.

SJRWMD does have a larger plan. But it is scattered across water-supply plans, groundwater models, utility permits, recovery strategies and construction projects. The public-facing message remains much simpler: Don’t water. The aquifer has not recovered. Keep waiting.

More Rain, Less Evapotranspiration and a Worse Aquifer Index

SJRWMD reported that its districtwide groundwater index stood at the 15th percentile in July, within the “low” range. August brought more rain. The district averaged 6.84 inches, while evapotranspiration—the water returned to the atmosphere through evaporation and plant use—averaged nearly five inches. Rainfall therefore exceeded evapotranspiration by approximately 1.8 inches.

Yet the Upper Floridan aquifer index fell from the 15th percentile to the ninth, moving into the “very low” range. The district’s July report and August report document the change.

At first glance, that seems backward. Rainfall exceeded atmospheric water loss. Residents remained under Phase III. Frequent rain reduced irrigation further. Why did the groundwater indicator deteriorate?

There are scientifically plausible explanations. Rain first replenishes dry soil and shallow groundwater. Some becomes runoff. Some falls where the geology limits movement into the Upper Floridan aquifer. Recharge may lag rainfall by weeks or months.

Pumping also continues when sprinklers stop. People still bathe, wash, cook and flush. Businesses, utilities, power facilities and agricultural operations continue using water. Recharge can occur while pumping and natural groundwater discharge still exceed it.

But the public report does not say which explanation controlled the August result.

It does not disclose whether absolute groundwater levels rose or fell, the average change in feet at the wells used, whether the same wells were included both months or how they were weighted.

A percentile compares current measurements with historical conditions for a particular time and place. Falling from the 15th to ninth percentile does not mean six percent of the aquifer disappeared. It may mean groundwater rose, but less than it normally rises during August.

The district possesses the individual well readings. The public receives only the index.

Why Isn’t There One Aquifer Gauge?

Many residents understandably imagine the aquifer as an enormous underground tank: insert an electronic gauge, measure the water depth and report whether it went up or down.

The Upper Floridan aquifer is more complicated. It consists of water moving through porous and fractured limestone beneath a large multistate area. Pressure and water levels vary with location, geology, rainfall, pumping and connections within the groundwater system.

SJRWMD does operate monitoring wells, including electronically monitored stations. It also uses the North Florida–Southeast Georgia groundwater-flow model for water planning, minimum-flow assessments and permit reviews. The model documentation says it incorporates water-use conditions used in the regional plan.

A groundwater model is not a direct meter. It combines well measurements with estimates of recharge, pumping, geology and underground water movement.

That complexity makes public explanation more important—not less. Residents should not have to accept a single percentile without knowing what physical change produced it.

Renewable Does Not Mean Unlimited

The aquifer is renewable because rainfall and groundwater movement replenish it. Renewable does not mean inexhaustible. A forest can be cut faster than it regrows. An aquifer can receive rain every year while people pump water faster than it can safely recover. The simplified balance is: Recharge and groundwater inflow – pumping and natural discharge = change in aquifer storage

Natural discharge sustains springs, rivers, lakes and wetlands. Excessive pumping can cause environmental harm long before an aquifer runs dry. SJRWMD Executive Director Mike Register put the principle plainly in 2026: “Florida’s water resources are abundant, but they are not unlimited.” His published commentary connected conservation with growth, aquifer protection and the rising cost of new supplies.

If the resource is limited, how much usable capacity remains after protecting natural systems? How much has been committed to development already approved but not fully built?

Phase III does not answer those questions.

The District Already Knows Groundwater Alone Is Not Enough

In December 2023, the Governing Board approved the North Florida Regional Water Supply Plan through 2045. Its central finding was unmistakable: traditional groundwater alone cannot meet the projected 135-million-gallon-per-day increase in demand while protecting water resources and ecosystems.

The plan identifies more than 160 million gallons per day of conservation, supply and resource-development projects intended to close that gap. SJRWMD published that conclusion.

That is effectively a carrying-capacity finding. The limit can change with conservation, reclaimed water, recharge projects and other supplies. But the district has already determined that projected demand exceeds what traditional groundwater can safely provide.

Today’s drought sits on top of that known long-term problem.

While Phase III Continued, the Board Approved More Pumping

The district’s May 12, 2026 meeting illustrates the competing policies.

Staff updated the board on water-shortage declarations. During the same meeting, the board increased the Upper Floridan allocation for the J.R. Kelly Generating Station from 0.693 million to 0.871 million gallons per day through 2046 because of increased power generation.

It also increased Lake Utility Services’ Floridan allocation from 5.32 million to 7.85 million gallons per day “due to population growth in order to meet projected potable water demands.” Chair Rob Bradley then requested a future discussion of alternative supplies. The meeting minutes document those actions.

On Aug. 11, while Phase III remained in force, the board renewed St. Johns County Utilities’ permit at 21.58 million gallons per day. The allocation may increase to 27.11 million through 2045 if the utility satisfies conditions involving a project to offset effects on the Lower Santa Fe and Ichetucknee rivers. The official minutes record the permit.

Those permits may meet every legal and scientific requirement, and an allocation is not necessarily current pumping. But the policy contrast remains: residents face emergency restrictions while the board authorizes additional long-term groundwater use for power and population growth.

The district’s answer is not necessarily to limit growth. It is to offset its effects.

What Is the Actual Recovery Plan?

Two projects are central to North Florida’s strategy.

The Black Creek project diverts excess high-flow water from the South Fork of Black Creek, treats it and sends it through Alligator Creek and Lake Brooklyn to support aquifer recharge. It can divert up to 10 million gallons per day, but only when creek flows are sufficient. The district says low-flow conditions prevent diversion approximately 25 percent of the time. Its current estimated cost is $118.7 million. SJRWMD describes the project and limitations.

Black Creek is a substantive response, not another request to reset irrigation timers. But its maximum contribution is only about 7 percent of the region’s projected 135-million-gallon daily demand increase—and it cannot operate at maximum capacity every day.

Water First North Florida proposes moving approximately 40 million gallons per day of highly treated reclaimed water from the Jacksonville area through additional natural treatment and back into the Floridan system. Its goals include restoring river flows and supporting communities and future economic activity.

In November 2025, the board approved a recovery strategy and authorized negotiations for up to $2.17 million in engineering work for site investigation and conceptual design. The meeting minutes document those votes.

Water First may become an important solution. It remains a developing project, not an immediate remedy for today’s Phase III conditions.

What Did Phase III Actually Save?

Outdoor irrigation is a legitimate conservation target. Drinking-quality groundwater should not be wasted through broken equipment, runoff or automatic systems operating during rain.

But Phase III has created a revealing test. Residents were limited to one irrigation day, and frequent rain eliminated much of the need to use it. If lawn watering is a principal source of stress, utility demand should show a measurable response.

SJRWMD should publish monthly withdrawals before and after Phase III, estimated irrigation savings, pumping by major user category, aquifer changes in feet, recharge lag at the controlling wells and the remaining deficit after conservation.

If Phase III produced major savings, that strengthens the district’s case. If outdoor demand collapsed while the aquifer indicator worsened, it does not prove irrigation is irrelevant. It proves the problem cannot be explained—or repaired—through lawn watering alone.

Give the Public One Understandable Water Balance

The fair criticism is not that SJRWMD has no plan. It has monitoring wells, groundwater models, conservation programs, permit conditions, Black Creek and Water First.

The problem is that its plan is fragmented while its public message remains centered on sprinklers and waiting.

Residents need one regularly updated North Florida water balance showing:

• Available supply after protecting natural systems

• Actual withdrawals by user category

• Aquifer levels and monthly changes in feet

• Estimated recharge

• Demand already committed to approved growth

• Water contributed or saved by each project

• Project schedules, costs and funding status

• The remaining surplus or deficit

• Exact benchmarks for ending Phase III

Jacksonville residents understood emergency conservation when rainfall collapsed. What is harder to understand is an “Extreme” order continuing through frequent rain and into a season of naturally declining irrigation—with no expiration date or measurable exit point.

Phase III may still be scientifically justified. If so, the district should publish the measurements and prove it.

But Phase III cannot become the plan.

SJRWMD has the science, models and authority. What it has not provided is the simplest thing: one understandable accounting of how much water North Florida can safely supply, how much it uses, how much additional demand government has authorized and when its proposed solutions will close the difference.

Until then, Phase III will continue to look less like a recovery plan than a Band-Aid—one left in place even after the lawn underneath it is already wet.
