On-Demand Irrigation

TID pioneered the concept of an on-demand water delivery system so farmers could avoid long waits between irrigations. With the exception of a small area in the Delhi area, all irrigation water is delivered via gravity through a system of canals and laterals between La Grange Dam on the Tuolumne River on the east and the San Joaquin River at the far western edge of the irrigation service area.
