Table 7. Recreational-landscape irrigation water withdrawals by County in Florida, 2015 In 2015, the total amount of water withdrawn for recreational-landscape irrigation uses in Florida was estimated at 398 million gallons per day (Mgal/d). Withdrawals include water used for golf course and public and commercial landscape irrigation (parks, ball fields, highway medians, cemeteries, and other large-scale grass or landscaping areas) that have a consumptive water use permit from the local water management district specifically for golf course or landscape uses. This category does not include individual household lawn irrigation withdrawals. Fresh surface water accounted for 216 Mgal/d of the fresh water withdrawn while 182 Mgal/d was withdrawn from fresh groundwater sources. Palm Beach County accounted...
