The Colorado River basin is suffering from an extended hydrologic drought, which has led to record low flows on the Colorado River. Discussions have been centred on reducing yearly irrigation amounts to the golf course industry to a value below 1.8m per year, leading to deficit irrigation. An on-going 5-year study of golf courses that are preparing to change water supply to reuse water found that:- (1) long-term (>30 years) use of reuse water will increase rhizosphere soil salinity as high as 40 dS/m; (2) spatial distribution of salts is closely linked to irrigation uniformity and the spatial distribution of soil moisture; (3) average leaching fractions on fairways are estimated to be 0.05 and on greens 0.20; (4) for bermuda-grass on reuse courses only very little change has been observed in parameters such as leaf water potential, canopy temperature and tissue moisture content, compared to fresh-water courses.
