January 2019

During the month of January, we received 112.5mm of rainfall and recorded 8 days of rainfall. Most of the rain falling on consecutive days from the 6.1.19-11.1.19.

To reflect on the year that was 2018, it was certainly interesting too say the least, I wouldn’t use the word “stressful” however it was extremely frustrating to see the course deteriorate due to influences outside of my control. Mainly the issues with Sydney water and the Area Health Department in the restrictions imposed on the volume and quality of the water supplied, and it has now been 15 months since the supply was disrupted.

We are in a difficult position where the water supplied is not keeping up to the demand needed for the turf to stay healthy and we are now more reliant on frequent rainfall than we have been in the past when supply was good.

Here is a quick insight to how much water is needed per irrigation cycle across greens, tees and fairways, with a 30-minute runtime on each sprinkler.

Below is the volume of water used across the course in one application.

Greens= 240,000 liters per cycle every second night in hot temperatures

Fairways =495,000 liters per cycle (currently once a week but should be 3 times / week).Tees = 60,000 liters per cycle (currently once a week but should be 3 times a week.)

Now consider; Evapotranspiration is the sum of evaporation and plant transpiration from the earths soil and the oceans surface to the atmosphere.

Evaporation accounts for the movement of water to the air from sources such as soil and plant canopy and water bodies.

A simple equation 30 minutes of irrigation = 6mm of water applied.

A day with temperatures around 20 degrees has an evapotranspiration of 2mm.

A hot windy day of 30 degrees + has an evapotranspiration rate of at least 8-10mm of water loss from the plant, therefore you can now understand how keeping up with the water application can prove difficult and why the health of the turf is compromised.


Green are performing well at the moment with the aim of consistency.

With the temperature on the rise so does our need to irrigate greens, this results in a softer playing surface and less resilience to golf ball damage.

Pitch marks need to be repaired correctly to ensure a quick recovery, a poorly repaired pitch mark can take up to 6 weeks to recover as compared to 24 hours for a correct repair, this is an investment for golfers to play on better greens.

Feel free to chat with any member of the greenstaff to show you the correct way to repair a pitch mark.

Our programs for Disease and insect control are working well and on budget.

Greens are being cut 5-6 times per week.

Greens are the main priority for water usage.


Tees are in good condition with usual un repaired divots!

We cutting tees twice weekly.


The fairways are very dry due to the issues with the volume of water supplied and without consistent rainfall the condition will continue to deteriorate quickly.

Irrigation is not enough to replace the water loss due to the high temperatures.


At this stage all machinery is working well.


We have topped up the bunkers on the front of the 6th green, right hand side of the 11th and both bunkers on the 13th.

General trimming occurs once a month at the moment.

Trees and Gardens

Three medium size dead pines were removed from the area between the 7th and 16th greens.

The next major garden maintenance will be hedge trimming across the course.


General maintenance including the relocation of road base to repair low areas and step ups to tee areas.


No vandalism has been recorded for the month of January.
