~ . . Draft Water and Storage Needs Assessment SECWCD/Assessment Enterprise ii September 23, 1998 3. For the high growth scenario (159,000 af of additional water demand), the total additional water supply need is estimated to be 68,000 af, as shown in the table below, primarily in Colorado Springs, the other Fountain Valley entities, and several towns west of Pueblo. The Colorado SpringslFV A demands represent 97 percent of this potential water supply need. The supply/demand comparisons have assumed that the Fry-Ark Project yield is 80,400 af per year. Historical yield has been closer to 60,000 af per year. As municipal demand increases, municipal entities will begin using greater amounts of Fry-Ark Project water. Under the forecast, municipal entities will begin to use their Fry- Ark supplies more heavily, approaching their 51 percent allocation by the year 2020. This will impact current uses of Project water by agricultural entities for supplemental irrigation and replacement supplies for well depletions, '..,.."..."......."'..'...'....

Deficits assumed to be met by Fry-Ark Project water by year 2010. 4, Most of the municipal water supply entities have water rights to meet their 2040 needs, However, storage capacity is needed to provide firm yield and to facilitate water exchanges and management of imported water reuse, i 5, Average annual agricultural water use in the District is estimated to be 825,000 af(for ' I ditches and canals between Pueblo and John Martin reservoirs), Agriculture relies heavily on "supplemental" sources including transmountain water, Fry-Ark water, Winter Water, storage reservoirs, and ground water. (Direct flow water accounts of 86 percent of agricultural use in a "wet" year, but only 65 percent in a "dry" year), 6. Storage needs in the District are projected to range from 75,000 to 125,000 affor the base and high municipal demand forecasts, This storage need includes dedicated Project storage capacity for Winter Water.
