Drainage next to #10 green

Recently we noticed the area behind and to the left of #10 green was getting very wet and muddy. This was a red flag since there had been no rainfall in over a week. We searched the area for clues as to where there was a possible irrigation or drainage issue, and found a small trickle of water coming up through the turf behind the green. 

We used the hose you see in the photo to try to clean out the exit line from the drain box shown at the bottom of the photo. No such luck. We ran a snake down the exit line and it got stuck about 25 feet from the box. Time to start digging. We dug a hole behind the green, found the line, and kept digging along the pipe until we found a section that was crushed. 

The pipe was installed twenty years ago when the green was built. It's amazing that it was able to run water all that time. Why did it get backed up now? We dug up the crushed section and put a snake in it and found the line crushed again another thee feet down.

 It was time to dig from the box all the way out and across the cart path behind #10 green. 

We also added a new section of drain line along the hill into the box. A new line was also installed from the box across the path discharging over the back of the road. We'll closely monitor this area to make sure it's working over the next several months.
