<br /> 1,573,297 Thi~ represents 85% of the Ba~in pi>pulation. Ba~ed on this %, an additional 11.200 acre 74,800
<br /> feet or more, may nced to be added to the 74,800 AF already identified to meet demands
<br /> throughout the entire basin.

<br />
<br />Projections are as the entitles reported them to the Farm Bureau. Not all entities have done long term projections.
<br />*Additional Watcr Needs wcre calculated by subtracting the smallcr of the existing yield numbers from the estimated 2030 Water Demands values.
<br />
<br />Compact Requirements:
<br />
<br />Colorado has the right to fully use the waters of the Soulh Platte between October 15 and April I. Between April I and October
<br />15, if the mean flow of the South Platte at Julesburg drops below 120 cfs, water rights on the South Platte in Colorado between
<br />the western boundary of Washington County and the state line (Lower Section) with priority dates junior to June 14, 1897 are
<br />curtailed, Colorado reserves the right to develop 35.000 acre-feet of storage in the Lower Section. but only in the event that the
<br />Perkins County Canal in Nebraska is built. That canal would divert flow from the South Platte near the town of Ovid into
<br />Nebraska.
