The Cal Poly Irrigation Training & Research Center, working under a technical services agreement with the United States Bureau of Reclamation Mid-Pacific Region, has undertaken review of the procedure and materials used to create estimates for Irrigation Allowance Index evaluations and Crop Water Requirements for the growers in Stockton East Water District. These values will be used to create a real-time irrigation scheduling tool for the growers as well as a simple evaluation of total water use at the end of the irrigation season.
