- 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 county‐level 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 33°C (one degree day) reduces biomass yield by 3%, with a value in 2007 of about $10 per acre.
