Overview of Agricultural Water Use in the Colorado River Basin: Insights from 2009 Meeting

This document summarizes the findings on agricultural water use in the Colorado River Basin, presented during the March 23, 2009, meeting by regional specialists Denis Reich and Rod Sharp from CSU Extension. Key data reveal consumptive use in agriculture, highlighting 88% of the in-basin consumptive use with detailed statistics on irrigated acres and total consumptive use by water district as of 1990 and 2004. Relevant comparisons and economic impacts are discussed, emphasizing the need for sustainable practices in agriculture amidst changing water availability.
