Golf courses account for approximately 3.2% of the turf. The primary objective of this research effort was to assess the watershed scale hydrologic and surface water quality impact from two well managed golf courses. Surface water hydrology and nutrient concentrations were measured for 5 years at Morris Williams Municipal Golf Course, Austin, TX and 2.5 years at Northland Country Club, Duluth, MN. A range of nutrient concentrations were detected in the surface water. Nitrogen and phosphorus loadings from these courses are generally greater than similar losses from native prairies and forest but less than loadings reported for agriculture.
