Irrigation Priorities

We are currently experiencing exceptionally dry weather conditions. Since 1st March our weather station has recorded only 32mm of rainfall, which represents less than 25% of the average for this period. These dry conditions have very often been accompanied by sunny and breezy weather, this has meant that we have been heavily reliant on our irrigation system to deliver the water required to keep the turf healthy.

We have been losing between 20 and 30mm of moisture from the turf each week from a process called evapo-transpiration. Although this does not sound too bad, to replace 25mm of water across the whole course means that we must apply around 1 million gallons of water. Consequently, we have been abstracting large quantities of water from our boreholes to replenish the water pumped from our reservoir.

In recent days it has been noted that the yield from the boreholes has decreased to the extent that we have been pumping water out of the reservoir and onto the golf course faster than we have been able to replace it. You may have noticed the low water levels in the reservoir recently whilst standing on the 14th tee. This is obviously an unsustainable situation and as we are still in the first half of the season with potentially a lot more dry weather ahead of us, we must now adjust our irrigation output to a sustainable level.

Currently two thirds of the water we apply is to fairways so clearly this is the area where the greatest savings can be made. It makes sense to prioritise the watering of greens, tees and approaches whilst reducing the amount of water the fairways receive. Instead of watering fairways every night, from now and until the next significant rainfall, we will water these areas on 2 or 3 occasions each week. This will ensure we will have enough water for the priority areas for the remainder of what could be an extraordinarily dry season.

Hello Ollie,
Hope you're well. Yes, we've had a massive 11mm in the past 36hrs! Still, that nearly equals the rainfall for April and May combined!

159 washed out bunkers......You'll be as fit as a fiddle! unfortunately, I wont make it to Sandwich in July but I'm sure there will be a few from here make the trip.
