Abstract: The Imperial Irrigation District (IID) in southern California has an interest in water conservation measures. These measures depend on the quantification of water flows at various sites within the district. In this study, the random and systematic error components for individual flow measurements at five key sites into and exiting IID were determined. From these individual error components, an estimate of the uncer-tainty for the annual volume that passes through these sites was determined. This in-formation is expected to be used to identify opportunities for further improving water management practices within the district. The 95% confidence interval for the annual volume at 4 of the 5 study sites was±2.25%. The fifth site had a 95% confidence in-terval for the annual volume of±3.50%. Very little systematic error (bias) could be identified and most of the random error is compensated because of the large number of current meterings IID performs each year.
