I woke up this morning to a welcome sight. The rain gauge at the shop showed that we had received a little over 2" overnight. To say that a large rain event like this was needed is a huge understatement. We hadn't had any rain over 1" since June 4th! To make matters worse, during the month of July and first half of August, we were evaporating moisture out of the ground at a rate of .25" per day. This means that even though last nights rain is very helpful, and much needed, we are still over 13" behind schedule on our annual rainfall. We need several more big rain storms like this to make a meaningful impact on our subsoil moisture. This recent rain will however, have a big impact on the golf course turf and home lawns throughout the region.
The most noticeable thing that the rain did for us was give us some more irrigation water. Our irrigation supply is tied into two ponds on the course. The small pond on #4 is our primary irrigation pond and the larger lake down on #17 is our reserve. We can pull water from the lake up to the irrigation pond to meet demand. As you might have noticed, over the past 6 weeks or so, the lake on #17 has been very low. We have had to severely ration our water supply to ensure we could water the greens and not run out.
Over the next few days, you should be able to notice a big growth response from the turf now that a large amount of moisture is in the soil.
