Sink Hole on #18

When it rains it pours and as of today, we have had 30 plus inches of rain this year.  That rain has highlighted some deficiencies on the course, most notably rusted steel culverts.  While we have replaced most of the steel culverts, there are some that remain such as the one that travels across the fairway on #18.

After our last major rain event, we were welcomed by a large sink hole in the middle of the fairway on #18.  At the surface was what looked to be about a 5 foot hole, but upon further inspection, there was a much larger cavity below the sod.  We immediately closed the hole for safety reasons.  It did not take long to figure out what the problem was, a rusted 18 inch steel culvert.

Since the pipe was too deep for our staff to safely replace, we solicited bids to have the pipe replaced with double wall plastic pipe.  This pipe will last for well over 50 years.  While the job seems simple enough, there are electrical wires and irrigation pipes that have to be avoided.  Additionally, all subsurface drain lines need to be connected to new pipe.  With good weather, I expect this work to be completed by the end of this week.
New pipe extends all the way to the lake.
