Every time drought returns, golf finds itself back in the water debate.
The images are powerful: green fairways surrounded by dry landscapes, sprinklers operating while households face restrictions, golf courses maintaining turf while farmers, businesses and local authorities are being asked to conserve water.
The criticism raises a legitimate question. But it also tends to produce misleading comparisons.
How much water does golf actually use? Where does that water come from? How much has consumption changed? And perhaps most importantly, does a national average tell us anything meaningful about the pressure created by a particular golf course during a drought?
In 2026, those questions became particularly relevant in Britain. In August, The R&A reported that England had received just 5.6 mm of rain in July — 8% of its long-term monthly average. Wales received 7.9 mm, also around 8% of average, while Southern England experienced its driest month since records began in 1836.
Water is no longer simply an environmental issue for golf. Increasingly, it is an operational one.
In the United States, golf is using 31% less water than in 2005
The United States provides some of the most comprehensive long-term data available.
The latest Golf Course Environmental Profile survey, conducted by the Golf Course Superintendents Association of America and partly funded by the USGA, collected responses from almost 1,700 golf facilities.
Its conclusion is significant: American golf courses applied 31.2% less water in 2024 than in 2005.
Total water applied fell from approximately 2.38 million acre-feet in 2005 to 1.63 million acre-feet in 2024, equivalent to roughly 2 billion cubic metres. Since 2020 alone, consumption has fallen by another 3.2%.
There is an important qualification.
Part of that reduction comes from having fewer golf facilities. According to the study, however, approximately two-thirds of the overall decline is likely to have resulted from operating golf facilities using water more efficiently. Median water use per acre was 15.4% lower in 2024 than in 2005.
That distinction matters. Golf has not reduced water use simply by closing courses.
Existing courses are using less water too.
Where does the water come from?
The same American study provides another piece of information often missing from discussions about golf and water: its source.
In 2024, the most common irrigation sources on US golf courses were wells at 32%, lakes and ponds at 27%, and recycled water at 19%.
That matters because one cubic metre of water is not necessarily environmentally equivalent to another.
Potable mains water, groundwater from an aquifer under stress, captured rainfall, recycled wastewater and water stored in an on-site reservoir may all appear as water consumption in a golf course’s accounts. But the pressure each places on local water resources can be very different.
This is where national comparisons begin to lose some of their meaning.
The USGA estimates that golf courses account for approximately 1.3% of irrigation water use in the United States. That puts golf’s national footprint into perspective, but it does not establish whether a specific withdrawal is sustainable in Arizona, Nevada or another water-stressed location at a particular time of year.
The important question is therefore not simply how much water golf uses, but what water it uses, where it uses it and when.
Britain discovered in 2026 that water scarcity is not only a southern European problem
The same principle applies in a very different climate.
Golf in Britain has traditionally been associated with rainfall rather than water scarcity. But that assumption is becoming increasingly unreliable.
In November 2025, the Environment Agency warned that a dry winter could significantly restrict irrigation capacity during spring 2026. Its assessment specifically identified golf courses, noting that many clubs depend either on mains water or abstraction without sufficient storage. Restrictions could therefore threaten turf survival on greens and tees. GOV.UK
Those concerns were followed by an exceptionally dry summer.
By July 2026, water companies in parts of England were implementing or preparing temporary use bans as low river flows and increased demand put pressure on supplies. Government drought reports specifically recorded water companies contacting golf clubs as part of efforts to reduce demand.
Then came the extraordinary July rainfall figures: 5.6 mm across England and 7.9 mm in Wales.
The R&A responded by urging golf courses to use its Golf Course 2030 Water Portal to assess their vulnerability and develop longer-term water management strategies.
This is an important change in the debate.
Water resilience is no longer something only desert golf courses need to think about.
Golf has become increasingly dependent on irrigation
The R&A identifies a structural problem behind this vulnerability.
Over the past 40 to 50 years, golf courses have become increasingly reliant on artificial irrigation to maintain and improve turf quality. The organisation argues that courses now need sustainable and secure long-term water sourcing strategies rather than assuming that sufficient water will always be available.
That dependency is partly technical, but it is also cultural.
Golfers became accustomed to increasingly consistent playing surfaces and, in many markets, to an aesthetic in which green became synonymous with good conditioning.
Water scarcity challenges that expectation.
A course can remain playable without being uniformly green. In fact, maintaining turf under drier conditions is already among the water-management practices increasingly adopted by American superintendents.
That may require golfers to reconsider what a well-maintained course actually looks like.
The biggest savings may come from irrigating less land
There is no single technology capable of solving golf’s water problem.
The USGA’s Water Conservation Playbook, published in 2025 following a 15-year, $30 million investment in water conservation, identifies nine strategies ranging from basic irrigation maintenance to soil-moisture monitoring, drought-tolerant grasses, subsurface drip irrigation, recycled water and reducing the total acreage requiring irrigation.
Some solutions are deceptively simple.
Broken sprinkler heads, worn nozzles, incorrect sprinkler arcs and poor system pressure can send water where it is not required. Regular maintenance can therefore reduce waste while simultaneously improving playing conditions.
More sophisticated systems use weather stations, soil-moisture sensors and remote sensing to determine where water is actually required instead of irrigating according to a fixed schedule.
But one strategy stands above the others in terms of theoretical savings: stop irrigating areas that do not need to be irrigated.
The USGA states that no strategy saves more water over a given area than eliminating irrigated turf, provided the replacement landscape can survive with little or no supplemental water. It also warns that turf conversion is neither free nor simple: alternative landscapes require planning, establishment and ongoing maintenance.
This is an important distinction. Water conservation does not mean simply turning off sprinklers.
It means redesigning how a golf course uses water.
Recycled water helps, but it does not make water consumption irrelevant
Recycled wastewater is frequently presented as one of golf’s most promising alternatives to potable or freshwater irrigation.
The USGA explicitly includes recycled water among its nine principal conservation strategies and recommends connecting courses to recycled supplies where they are available and technically appropriate.
The 2024 GCSAA survey shows that recycled water already represents 19% of irrigation sources at American golf facilities.
But recycled water is not a universal answer.
Infrastructure has to exist. Transporting water can require pipes and pumping. Water quality can create agronomic issues. Storage may be necessary, and the economics vary considerably from one course to another.
The objective should therefore not simply be to replace one water source with another while maintaining unlimited demand.
The stronger strategy is twofold: reduce the amount of water required and improve the sustainability of the water that remains necessary.
France has introduced an interesting experiment in transparency
France provides a useful European example of what regulation could look like when water becomes scarce.
Under national drought guidance amended in July 2026, golf irrigation becomes progressively restricted as drought levels increase. At the highest crisis level, irrigation is limited to greens, capped at 350 cubic metres per week for each nine holes, and must take place at night. Courses subject to restrictions must also report the volumes they withdraw to the authorities every week.
The French model is interesting beyond France because of that final requirement.
It moves the debate from promises to measurements.
If a golf course says it has reduced its water use by 40%, there should ultimately be a number behind the claim.
And that leads to one of the biggest weaknesses in the international golf-and-water debate: despite increasingly sophisticated sustainability messaging, comparable course-level data remain surprisingly difficult for golfers and the general public to access.
When does sustainability become greenwashing?
Golf clubs increasingly communicate about biodiversity, drought-resistant grasses, reduced pesticide use, irrigation technology, habitat creation and sustainability certifications.
Many of these programmes are worthwhile.
But none automatically tells us how much water a golf course actually uses.
For a meaningful assessment of water performance, five basic pieces of information would already tell us far more: annual water use, the source of that water, the acreage actually irrigated, water use per irrigated acre over several years, and whether those figures have been independently verified.
Without measurements, a photograph of a reservoir, a new irrigation system or a sustainability logo tells us very little.
The same standard should apply to criticism of golf.
An image of sprinklers operating during drought may look shocking, but it does not tell us whether the water is potable, recycled or stored rainfall, whether irrigation is permitted, how much water is being applied or what part of the course is being protected.
Evidence has to work both ways.
Golf will not win the water debate by pointing at bigger users
There is a temptation within golf to respond to criticism by identifying industries that use more water.
At national level, those comparisons can be useful. The USGA’s estimate that golf represents about 1.3% of American irrigation water use, for example, provides necessary perspective.
But it does not settle the argument.
Water is fundamentally a local resource.
A relatively small national user can still create pressure in a stressed catchment at the wrong time. Equally, a golf course using recycled water or captured rainfall may have a very different impact from another course consuming a smaller absolute volume from a vulnerable freshwater source.
The evidence also suggests that golf has substantial room to adapt. American facilities have reduced total water use by 31% since 2005 and water applied per acre by more than 15%. New technologies can make irrigation increasingly precise, while reducing irrigated acreage and changing turfgrass strategies can lower demand further.
The question therefore should no longer be whether golf uses more or less water than agriculture, industry or data centres.
It should be what water each golf course uses, where it comes from, when it is used and what the facility is demonstrably doing to use less of it.
For decades, uniformly green turf was treated as a visual shorthand for golf course quality. In a world of less predictable rainfall and increasing competition for water, that expectation may have to change.
The future of sustainable golf may not always be green.
And perhaps the most revealing number to watch over the next decade will not be how much water golf uses today, but how much it can prove it no longer needs tomorrow.
