Golf course irrigation demand, like drinking water, is highly weather dependent. A roughly constant flow of wastewater must be stored and apportioned onto the golf course so that the storage pond neither overflows nor goes dry.
Over the past 20 years golf course irrigation demand has ranged from about 39 MG during a wet year to 161 MG during a dry year. Average annual use appears to be around 97 MG. Refer to Appendix 5 for historical usage.
