Bulletin No. 71 - Carrying Capacities of Irrigation Canals

During the summer of 1897 the writer was enabled to make, with the help of his assistants, T. H. Humpherys, A. P. Stover, and W. D. Beers, a number of experiments on the carrying capacities of irrigation ditches and canals. The funds necessary to carry on these investigations were provided by the U. S. Geological Survey and the Agricultural Experiment Station of Utah. Shortly after the field work was completed the writer resigned his position with the College to accept that of chief engineer and superintendent of the Ogden Water Works and the Bear River Canal System, and his time has been so fully occupied since with other duties that he has not had, until now, an opportunity to compile the information collected two and one-half years ago and put it in shape for publication. About sixty experiments were made on irrigation channels, which varied in size from the small ditch carrying a few miner\u27s inches to the large canal carrying 225 second feet
