<br /> 1,573,297 This represents 85% of the Basin population. Based on this %, an additional 11,200 acre 74,800
<br /> feet or more, may need to be added to the 74,800 AF already identified to meet demands
<br /> throughout the entire basin.
<br />Projections are 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 from the estimated 2030 Water Demands values.
<br />Compact Requirements:
<br />Colorado has the right to fully use the waters of the South Platte between October 15 and April 1. Between April 1 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.
