Watershed management opportunities in the west (Abstract only)

A discussion is presented relative to the conservation of water producing areas of the State of California, to meet the anticipated needs of expanding population, agriculture and industrial development. The water producing areas of the state are divided into 4 zones: (1) the brushland belt occupying 17.5% of the state's area and producing 12.0% of the water supply, (2) the timber belt below the snow line 3,500 to 5,000 feet elevation comprising 12.5% of the state area and supplying 33% of the state's water supply, (3) the timber belt zone in the snowpack area with 9.0% of the state's areas and produces 38.0% of the water supply, (4) the alpine zone covering 3.0% of the state's area produces 14% of the water supply. Conservation practices are outlined for water and snowpack management in these zoned areas for planning more economical use of the products of water supply.
