Evaluation of irrigation systems in the Snake River Fan, Jefferson County, Idaho Item Info

A study was conducted to evaluate the present irrigation systems in the Snake River Fan, Jefferson County, Idaho. The study was made during the 1973 irrigation season. Representative fields were selected for measuring water application efficiencies; and, within these fields, specific furrows and border strips were chosen for description and analysis in order to evaluate the performance of the existing irrigation systems. Results of water application efficiency tests show an average efficiency of 24 percent for border irrigation, and 51 percent for furrow irrigation. Since there was no surface runoff, 76 percent of the water applied was lost to deep percolation from the border-irrigated fields and 49 percent was lost from furrow-irrigated fields. The average labor input far the area was 0.51 hour per acre per irrigation for border irrigation and 0.45 hour per acre per irrigation for furrow irrigation. The labor input did not appear to have a significant effect on water application efficiencies in the study area. The dominant factors that caused low water application efficiencies were long durations of irrigation for high intake rate soils and long irrigation runs.
