The objective of this research was to determine the conduction efficiency and water losses affecting the main canal of the Cumbaza irrigation system. Data collection was carried out in September 2020, through direct observation (of a set of evidences and external signs of the structural components of the canal under study). The thin-walled weir method was used to measure inflow and outflow and empirical formulas were used to calculate water losses due to infiltration. The average conduction efficiency of the canal was determined in two sections, the lined canal section and the unlined canal section, obtaining a conduction efficiency of 83.55% and 71.00% respectively, which is considered low since it presents seepage along the canal, which is below the values established for conduction efficiencies in lined and unlined canals. It was determined that the irrigation canal underwent deterioration due to the faults found in the study section, which is due to poor maintenance of the main canal, allowing the greatest loss of water from the canal to occur through infiltration. The infiltration value was calculated using the Davis empirical formulas for the lined canal sections and the Moritz formula for the unlined canal sections, obtaining an average loss of 0.068 l/sec and 2.476 l/sec, which is considered as high.
