  1. Presence of Golf Course Holding Ponds in the Coastal Environment Phil Rogers Coastal Management Fall 2001

  2. Purpose • The purpose of a holding pond on a golf course is to trap run-off coming from various locations on the course mainly the tees, fairways, and greens. • Trapping this run-off allows for the primary breakdown of many harm-full chemicals that are applied to these courses before they can enter into the Coastal environment.

  5. Why is this important • The number of golf courses in the coastal environment is huge and ever growing. • These courses apply immense amounts of chemicals including herbicides, pesticides, and fertilizers. • example: In 1999 30 tons of fertilizer and 800 gallons of pesticides were applied to the Wilmington City golf course

  6. Sensitive environment • The Coastal environment is home to many organisms that are very sensitive to chemical insults especially those in stages of early development. • Also the sandy nature of the soil in a coastal environment allows for many chemicals to migrate.

  7. Effectiveness • The holding pond system has proven to be an effective way in treating many chemicals applied to the course before they can get off site. • However they are not full proof, but with the amount of chemicals being applied they can not be.

  8. Problems • Problems arise with the holding pond system during large rain events that cause the pond to overload and breech. • Small rain events can cause problems if the chemicals are applied just prior to the rain event. • Over application of chemicals

  9. Solutions • A tiered system of ponds is being used in some areas which allows for greater amounts of run-off to be trapped for longer periods of time. Added time in the ponds gives the chemicals longer periods to breakdown before they enter the coastal environment. • Chemicals must be applied at the correct times. This includes both time of year and rain events. • Application rates must be logged and monitored.
