The Second Management Plan, adopted in 1989, is the second in a series of five management plans required by the 1980 Groundwater Management Code. The plan guided water management efforts in the Active Management Areas during the last decade of the 20th century. The conservation programs for agricultural, municipal and industrial waters users, introduced in the First Management Plan, have been strengthened; and the water resources analysis of the Active Management Areas have been revised. With the addition of two new programs - water quality assessment and management, and water supply augmentation and reuse - the Second Management Plan presents a more comprehensive water management strategy. The plan's requirements are designed to bring water users another step closer to achieving the water management objectives for the Active Management Areas.
