Laguna Irrigation District was formed in February 1920 under Irrigation District Law to deliver water to farmers and landowners within the District. The development of irrigated agriculture around the LID area began with the development of facilities by the Fresno Canal and Irrigation Company whose successor, the Fresno Canal and Land Corporation, sold the system to LID in 1921. The District service are includes a substantial portion of the historic Laguna de Tache Land Grant.

Laguna delivers agricultural surface water through approximately fifty miles of canals and a similar mileage of pipelines. We provide surface water to an area of southern Fresno County and Northern Kings County southwest of Kingsburg and south, southeast, and southwest of Riverdale with the southerly boundary generally along the South Fork of the Kings River or the Kings County line, and multiple points of diversion from the Kings River that supply the District conveyance system - Grant Canal, A Ditch, Island Canal, and Summit Lake Ditch.
