During the course of the seasons, the SOAR target area varied in size, but for the purpose of this report, the target area coverage of 5.048 million acres is assumed throughout the seeding season.
Assuming the SOAR target area at 5.048 million acres and Yoakum county covering an area of 511808 acres and cost sharing an amount of $20000 towards the SOAR operational costs, an average cost per acre foot of water produced by cloud seeding can be mathematically calculated using the 2002 and 2003 results.
Therefore, the cost for cloud seeding in Yoakum County in 2003, based on average total values of rainfall increases of seeded clouds versus matching non-seeded clouds can be assumed at a maximum value of 79.4 cents per acre foot of water produced by cloud seeding.
