As the need to be more efficient users of water, superintendents have used far less water during the past two decades.
According to a survey by the GCSAA and USGA, U.S. golf courses used 31 percent less water in 2024, compared with usage in 2005. The 2025 survey was conducted as part of its Golf Course Environmental Profile program, which began in 2005.
The report states that U.S. golf facilities used 1.63 million acre-feet of water in 2024, representing a 3.2 percent reduction since 2020 and a 31 percent reduction since 2005.
Water use on U.S. golf courses is down by 31 percent in the past 20 years, according to a GCSAA survey.

From 2020 to 2024, the Southwest and Upper West/Mountain regions reported the highest reductions, using 16.9 percent and 7.8 percent less water, respectively.
The survey results from nearly 1,700 golf facilities were collected and independently analyzed by scientists Travis Shaddox, Ph.D., Bluegrass Art and Science LLC., and Bryan Unruh, Ph.D. University of Florida, and the National Golf Foundation. The findings were published for peer review in the HortTechnology Journal in September. The most common sources of golf course irrigation water, according to the report, were wells (32 percent), lakes and ponds (27 percent), and recycled (19 percent).
Much of the reduction in water use can be attributed to the focus on and implementation of BMPs nationwide. The most common water-management practices across the regions include the use of wetting agents, hand-watering and managing turf under drier conditions.
Golf facilities also have been incorporating more technology into watering decisions in the way of hand-held moisture sensors, irrigation scheduling, irrigation audits as well as using ET data from onsite weather stations. New irrigation system components, new nozzles, updated software and master controllers also contribute to greater water-use efficiency.
GCSAA will publish additional national reports related to pesticide use and nutrient management on golf courses over the next year as part of the fourth series of its Golf Course Environmental Profile program.
