<br /> 379,688 This represents 47% of the basin population. Based on this % an additional 10,000 At least
<br /> acre-feet or more may need to be added to the 22,000 AF already identified to meet 22,000
<br /> demands throughout the entire basin.
<br />Projections go out as far as the entities reported them to the Farm Bureau. Not all entities have done long term projections.
<br />~Additional Water Needs were calculated by subtracting the smaller of the existing yield numbers (where available) from the estimated 2030 Water Demands
<br />values.
<br />Arkansas River Compact of 1948:
<br />The compact apportions the water of the Arkansas River between Colorado (60%) and Kansas (40%). It provides
<br />for storage accounts in John Martin Reservoir (JMR) and the release of water from those accounts for Colorado and
<br />Kansas water users. If the conservation pool in the reservoir is depleted, Colorado is required to administer water
<br />right priorities downstream of JMR. During those periods, Kansas is not entitled to water flowing into the
<br />reservoir.
