Total employment would in- <br />~ crease from 0.4 million to 1,3 million for the same period. Total <br />~ personal income would increase from about $3 billion to over $40 billion <br />in 2020 and gross regional product from $3.3 billion to $50 billion. <br /> <br />Projected agricultural production consists principally of livestock <br />feeds and meat production, The harvest from an additional 65,000 acres <br />of irrigated land would be required. <br /> <br />Water and Related Resource Requirements <br /> <br />Annual water withdrawals would increase about 2.3 MAF and <br />depletions 1,5 MAF by 2020, Irrigated agriculture would remain the pre- <br />dominant use through 2020, although municipal and industrial use would <br />require the largest increase in supply. <br /> <br />Recreation and related land uses show the greatest increase follow- <br />ed by urban and commercial uses. Agricultural uses, principally <br />grazing, would decrease about 2 million acres. Conversion of cropland <br />principally to municipal and industrial use would require development of <br />245,000 acres of new. irrigated land. <br /> <br />Watershed land treatment and management measures would be required <br />on 40 million acres by 2020. About 12 million acres would require <br />intensive treatment measures. <br /> <br />Mineral production is expected to increase from $389 million <br />annually in 1965 to $630 million by 2020, Mineral production is <br />governed by national, rather than regional, requirements. <br /> <br />Flood damages exceeded $5 million in 1965, With planned flood <br />protection facilities and measures, projected damages in 2020 would be <br />reduced from $24 million to $7.8 million annually. <br /> <br />Total annual outdoor recreation demands would increase from 31 <br />million recreation-days in 1965 to 350 million in 2020. Water-based <br />recreation demands would increase from 41,000 to 230,000 surface acres <br />in the same period. <br /> <br />Electric power requirements would increase from 5,500 <br />hours in 1965 to 160,000 gigawatt hours annually in 2020. <br />plants would replace most imports in the last time frame. <br /> <br />gigawatt <br />Nuclear <br /> <br />ii <br /> <br />, <br />, <br />, <br />~ <br />
