PGA Tour Set Up
I had the great pleasure of helping out on the maintenance crew at Silverado last week for the PGA Tour's Safeway Open. Working for former Sonoma Golf Club Superintendent Mat Dunmeyer is always a treat and last week was no different. I especially enjoyed seeing old friends and making new ones from all around the turf industry. My job assignment for the week was Back 9 bunker crew and I wanted to share an "inside the ropes" view of PGA Tour bunker preparations.
The vast majority of course preparations are spent in the weeks and months leading up to the event. Once tournament week arrives, the course is expected to be prepped and ready so the crew can get out and perform routine course set up without skipping a beat. When we arrived early in the week it was obvious the staff at Silverado had done well to meet their goals. The course was in fantastic condition and more than ready. This was especially true in the bunkers. Edges were crisp. Sand depths perfect. Ready for the big show. Then, leave it to Mother Nature and her ability to change even the best of plans. Rain fell Tuesday and while totals were low, it was enough to wet the bunkers and change conditions somewhat. Thankfully the rain let up early in the week leading to sun and perfect Napa weather. By the weekend, winds had picked up resulting in very dry bunker conditions and lots of debris clean up. My point here is...
The bunkers were prepared perfectly throughout the week and yet still, perfect consistency day to day and bunker to bunker was an impossibility. The preparation of bunkers was consistent each morning. The bunkers looked and played beautifully but conditions differed. A snapshot of reality for the tour and for day to day set up at every golf course. Please take a look at the below article from the USGA on bunker consistency.
Bunker Consistency - FIVE reasons why bunkers are not consistent - by the USGA
Despite the best efforts of any agronomic team, maintaining perfectly
consistent playing conditions in every bunker is not possible.
Although
golf course maintenance teams may spend more labor hours attending to bunkers
than greens, golfers will still find that bunkers are inconsistent. Maintaining
totally consistent playing conditions in bunkers is not achievable, nor is it
necessarily desirable. Here are five reasons why the playing conditions in
bunkers will never be perfectly consistent:
1. Sand
depth –
The depth of sand on the bunker floor has a profound impact on playability. If
the sand is too shallow, bunkers may be wet and firm. However, too much sand
yields soft conditions that increase the probability of buried lies.
Inconsistencies in bunker sand depth develop on a daily basis from events such
as normal play, raking and wind exposure. The recommended depth for bunker sand
is 4-6 inches but varies depending on factors such as the physical
characteristics of the sand and the properties of the underlying material.
2. Sun
exposure –
Bunkers that receive more sunlight will dry faster and play softer than those
that receive less sunlight. For example, east- and southeast-facing bunkers dry
faster in the morning than bunkers oriented to the west or the north, causing
them to play softer.
3. Wind
exposure –
Bunkers facing the predominant wind direction will dry faster and play softer
than bunkers that are shielded from the wind or face the opposite direction.
4. Play
volume –
Bunkers that receive more play will be softer and less consistent than bunkers
with very little play. Why? Golf shots, foot traffic and raking disturb bunker
sand and soften conditions.
5. Irrigation – Many golfers
wonder if irrigation systems can be designed to avoid adding water to bunkers.
Unfortunately, such a design is impractical due to the shape and strategic
location of many bunkers. Uniformly irrigating irregularly shaped playing
surfaces such as greens, green surrounds and even fairways often places adjacent
bunkers in the line of fire of sprinklers. If bunker sand is shallow, contains
fine materials such as fine sand, silt and clay, or has been contaminated with
organic matter, bunkers will retain moisture. Wet sand plays firmer than dry
sand, so bunkers that receive more irrigation and retain more moisture will
likely play firmer than those that are well drained and out of the way of
irrigation. In the Southwest, where there is little rain and high water demand
during summer, bunkers are often wet and firm due to frequent irrigation.
The
bottom line is that golf is an outdoor game with inherent variability. For
example, no two lies in the rough are exactly the same and, like it or not, the
wind blows on some days while other days are calm. Sometimes the wind even
blows from one direction in the morning and the opposite direction in the
afternoon. Golfers are encouraged to embrace variability in the bunkers and
throughout the golf course as a welcome challenge. Remember the wise words of
the late Payne Stewart, "A bad attitude is worse than a bad swing."

Section Collection, “Managing Bunkers,” or contact a USGA agronomist.
Fall Maintenance
This fall our maintenance routine has changed from years past. A sure sign that the work we have accomplished over the years has paid off. Greens were aerated with a solid tine and given a medium amount of sand topdressing. Fairways and approaches were slit-seeded with blend of Fine Fescue seed. Tees were aerated with a deep tine. No cores pulled. Less surface disruption and less impact on play. This work was complete in just over a week despite a few equipment breakdowns and being a bit short on staff. As always we do everything we can to minimize disruption to the membership while performing these important "preventative maintenance" tasks. With the first rains of the season falling last week the greens are growing at a good pace and we should be back in shape come this time next week.
My hat is off to the staff in the Turf Department for their efforts this season. Their work over the year and especially the last few weeks will ensure a strong finish to 2018 and will no doubt set us up for a fantastic 2019. We hope you enjoy the golf course this fall and we appreciate all the support in doing what is right for the health of the golf course.
