Abstract
This study provides an estimate of the gross value of irrigation water from the U.S. High Plains
Aquifer. We estimate a yield function for aggregated crop biomass production, based on countylevel
observations for 1960–2007. This study found that irrigation increases total biomass yield in this
region by an average of 51%. We estimate the average gross annual value of irrigation as of 2007 to
be $196 per acre, for a total of about $3 billion across the aquifer. We also estimate that on average
across the aquifer, exposure to 24 hours of temperatures above 33C (one degree day) reduces biomass
yield by 3%, with a value in 2007 of about $10 per acre.
