Book excerpt: Excerpt from Report of Irrigation Investigations for 1900 Under the Supervision of Elwood Mead, Expert in Charge of Irrigation Investigations In this connection the studies of seepage and evaporation have proven to be of especial value. The losses in distribution are more serious than has heretofore been estimated by writers on this subject or was realized by canal owners or managers. The studies Of the amount and influence of sediment have also thrown light on some Of the most perplexing problems with which the proprietors of reservoirs and ditches have to deal. While these investigations are designed primarily to aid farmers already engaged in the reclamation of the arid lands in the W'est, they have a vital importance to the country at large. Should Congress in the near future, extend aid in some form in the construction of irrigation works of too great magnitude and cost for private enterprise, the works so built should be based on accurate knowledge of what is necessary to give them enduring value. In constructing reservoirs it is as necessary to know whether they will be filled in a few years by silt as to know that the dam rests on a solid foundation; and it is as desirable to provide some means for the removal Of this sedimentary accumulation as it is to provide an adequate wasteway for floods. III planning diversion works it is as necessary to know how much water it takes to irrigate an acre of land as to know how much water is available for such irrigation. The work that the Office of Experiment Stations is doing in showing where and how water can be used to best advantage forms a complement to the work of other departments in showing where and how it can be secured.
