Another System

Once again Mother Nature blew through a powerful system.  Rain came down hard and fast washing out bunker edges and creating standing water throughout the course.  Today is spent on debris cleanup like pumping bunkers, skimming soil off the top of bunker sand, and raking washed debris.  These are the days that throw wrinkles into our plan but it is the nature of the beast.  Some good that comes out of these times is it gives us good ideas where we are having issues with our already existing drainage but also where we need to look into the addition or upgrading the drainage.  The drainage work that we've been doing is paying off.  Greens drainage is working like a charm, lake overflow on 3 pond is running right through and we no longer have water coming up through the fairway, and the replaced drainage on 10 is pumping water right into the lake.  It's always very encouraging to see projects turn out the success you hope for.  More pictures will come this afternoon, charging the battery at this moment.  For the meantime here are some photos collected this morning.

Left green side bunker on 16.  Shows the sand that gets washed down from the edge and the soil becomes exposed.  Hard not to notice the amount of water still standing in the bunker.  Heavy rain was finished by 9pm the night prior so this is roughly 12 hours after the rain had stopped.  Water should be gone.

Bunker behind 16 green.  Here shows again the sand that gets washed down from the edge and the soil being exposed.

Right side greens bunker number 12.  This bunker always gives us fits in heavy rain.  Lots of things contribute to this problem.  1.) The tiling system that comes to the bunker.  This is along a long stretch of main tile from behind 2 green and goes all the way to the rightside of 17.  Tile size behind 2 is 10", that is then reduced to a 6" tile across 7 fairway and right next to the bunker where it enters a catch basin, that then is reduced to a 4" line that runs under the bunker.  With the reduction of tile size the water backs up and floods next to the bunker.  2.) When that water floods the area next to the bunker the bunker edge is to low and allows that forced water up through the catch basin to then run right through the bunker.  Fixes will be upgrading tile size or retrenching a line around the bunker to take the heavy flow away as well as raising the right side of this bunker to divert the water around the sand trap and down into the fairway where there is a series of catch basins.

This is a tile the comes out the back of 16 green and just opens up to the low area behind the green down by 13 tee.  This pipe should be connected to the underground system.  All this does is flood that area, see picture below.

Area affected by the tile in the above photo.  This needs to be trenched down to the catch basin along the cart path between 13 and 17 tees.
