<br />. <br /> <br />002534 <br /> <br />. <br /> <br />SECTION VI <br /> <br />ARKANSAS RIVER SUPPLY <br /> <br />Most of the hydrologic data analyzed and presented by <br />both states covered the period from 1950 through 1985. 1950 <br />corresponds to the first year after the approval of the compact, <br />and 1985 is the last year before commencement of this action. This <br />period of time was also used by Kansas in its hydrologic- <br />institutional model and by Colorado in its water budget analysis. <br />However, certain older reports that included river flow data from <br />earlier years were also submitted into evidence, particularly with <br />respect to the mainstream inflow at Canon City before Pueblo <br />Reservoir was constructed, and the river flows at the Stateline. <br /> <br />Both states used measurements just downstream from Pueblo <br /> <br /> <br />Reservoir to represent the supply of the mainstream. These data <br /> <br /> <br />included some transmountain imports, and in more recent years also <br /> <br /> <br />reflected the impact of storing winter flows in Pueblo Reservoir <br /> <br /> <br />for later release. However, the total amount of water available <br /> <br /> <br />for downstream use includes more than just the mainstream inflow at <br /> <br /> <br />Pueblo. Tributary inflow, releases from other downstream <br /> <br /> <br />reservoirs, groundwater, precipitation, and return flows from <br /> <br /> <br />stream diversions and groundwater pumping all add to the total <br /> <br /> <br />water supply available in Colorado. <br /> <br />136672 <br /> <br />-54- <br />
