Collar Dams

A common reason for ice formation on greens is what we refer to as a Collar Dam.

Over time, top dressing and bunker sand builds up on the collar, creating a roll and trapping water on the green. The water freezes and damage occurs as we see here on the 6th green.

The damaged area was sodded and the area leveled to allow for proper water drainage off the green. Hopefully, this will prevent damage from occurring in this area in the future.
