Before shutdown in the fall, we check and open every surface drain and mark it with a flag. By removing the caps on small surface inlets we provide an easy channel for water to escape. The quicker we can remove surface water the smaller chance of ice buildup, and we have discussed the dangers of prolonged ice cover on turf.
Most of the South Course surface drains ultimately move water to either the pond on #16 or the pond on #7. All of this water exists the property through the creek on #5 out to Lahser Road.
In the spring, Copper Sulfate is added to some of the drains to reduce root encroachment from nearby trees. Or as Dr. Vargas calls them .... "weeds that got hard".
