From my friends at the USGA. |
Here are some interesting figures to keep in mind as you watch the U.S. Open: 11 to 12: The target green speed measured by a USGA Stimpmeter. 0.45: The approximate mowing height of the fairways in inches. 40: The acres of rough turf removed during the 2010 restoration project, reducing maintained turf to 50 acres. 650: The number of irrigation heads removed during restoration project. Total water usage was reduced 70%. 70: Number of plant species found in the sandy wiregrass areas. |
