Hydraulic leak on #16 green

I was mowing greens this morning in preparation for our outing that was going off at 11:00 a.m. when we experienced a hydraulic leak on #16 green.  The leak occurred on the top tier about 15' long and possibly a foot wide the way it sprayed onto the turf.  We scrubbed the area with soap but more than likely will be losing some turf.  We will be monitoring it over the next few days and will replace the area as necessary.
