Fig. 4. Annual areal weighted irrigation volumes for managed turf (tees, greens, and fairways) at Morris Williams Municipal Golf Course (MWMGC). Boxes are bound by 25th and 75th percentile values; line in the box represents the median. Monthly volumes were calculated from applied volume multiplied by fractional area: volume applied to greens x 0.025 + volume applied to tees x 0.01 + volume applied to fairways x 0.284.
