Green Speed

Putting greens are not all of the same quality. The finest-quality greens are well-kept so that a ball will roll smoothly over the closely mowed grass. Golfers describe a green as fast if a light stroke on the ball makes it roll a long distance; conversely, on a slow green a stronger stroke is necessary to roll the ball the same distance. The exact speed of a green can be determined with a stimpmeter. The stimpmeter is a device used to measure the speed of a golf course putting green by applying a known force to a golf ball and measuring the distance traveled in feet.

The USGA following recommendations:[1]

 Speed Length
Slow 4.5 feet (1.4 m) 
Medium 6.5 feet (2.0 m) 
Fast 8.5 feet (2.6 m) 

Tri Mountain Golf Course will average around 9.5 until the first weekend in July. July through mid-September green speeds will increase and average around 10.5. Green Speed will be the center of discussion over the next month with the 2015 US Open visiting us here in Washington the week of June 15th - 21st.
