Pasture and hay acreage were taken from the Census of,Aqriculturs, which is published every five years. This section used Census data for the year 1969, published in 1972. The changes in the data on pasture and hay between 1969-1974 are insignificant for purposes of this analysis. All other acreage data are from the Colorado State Aqricultural Statistics and are constant for the year 1974 regardless of the year of their most. recent publi.cation. The changes in land use patterns between 1974 and the present only serve to reinforce the Projections for Expansion made in this table. Thus, picking another base year and recomputing land use relative to it would be a useless exercise, since the important variables for computing I~creaqe of New Development" are the npercentage Projection for Expansion" and the "Weighted Average Water Depletion per Acre.n b. Water Depletion equals the sum of consumptive use and incidental loss under current technology and management. c. Equivalent full irrigation based on available water of zero acre-feet for the likely estimate and 35,700 acre-feet for the high estimate. (See Tables 1 and 2.)
