Show UPPER VALLEYS IRRIGATION. When Done Early in the Season It Increases In-creases the Stiver's Flow in the Lower Valley Other Important Information, Useful to Farmers, The Utah Experiment station, Logan, Lo-gan, Utah, has issued bulletin No. 38 on "Seepage Waters and the Underflow Under-flow of Rivers." During the summer of 1894 m&vy me: aarements were made of the cana s and tributaries of the Ogden and Weber livers to determine, if po sible,whether water could be diverted ajd applied to the surface of cultivated areas in the upper yalleys without iDjurv to the priority users in the lower valleys. The prelininary investigation s.which extended through July and August a period much too brief in which to base accurate results seemed to demonstrate demon-strate the accuracy ot the following results: 1 : That the tfi vers ion of water from a stream and its application to the soil in the upper valleys in the early part of the irrigation season when water is abundant, increases the available supply sup-ply to the irrigators of the lower valleys val-leys in the latter part of the season. 2:-In most cases a time is reached, usually about midsummer, when no portion of the water diverted from the stream in the upper valleys reaches the lower irrigators in time to benefit them1) Such diversions and use damage the irrigators ir-rigators of the lower valleys. 8: In some instances the outflow from the upper valleys during July and August was much greater than the inflow, in-flow, although a laige part of the inflow in-flow was used for irrigation purposee. 4: The behavior of irrigation waters in any drainage system can be determined deter-mined only after a series of carefully made measurements extending oyer a period of years, and that much ill-feeling, trouble and litigation would be avoided if the state would collect the necessary data. This bulletin is now in press, and may be obtained on application to the office of the Experiment station,Logan, Utah. |
