Bulletin No. 240 - Effect Of Feed, Water, And Shelter Upon Fleeces Of Utah Ewes, A. C. Esplin

UAES Bulletins

Fleeces from range-bred ewes wintered on desert ranges are compared in this bulletin with fleeces taken from ewes of the same breeding wintered under farm conditions, involving regular feeding, shelter, and free access to water. Four hundred and sixty-two fleeces are included in the comparison.

Bulletin No. 183 - Water-Holding Capacity Of Irrigated Soils, Orson W. Israelsen, Frank L. West

UAES Bulletins

All information that will 'enable the irrigator to use water economically is valuable to arid-climate agriculture. In many arid-climate regions, including the western part of the United States, excessive waste of water occurs in the irrigation of highland porous soil areas, as a result of lack of information concerning the capacity of the soil to hold water. Following the waste of water on the uplands by excessive percolation through open soils, vast lowland areas are rendered partially or wholly nonproductive by water-logging. To illustrate, a gravelly bench soil four feet deep, if underlain by a coarse open gravel to a …

Bulletin No. 181 - Duty-Of-Water Investigations On Coal Creek, Utah, Arthur Fife

UAES Bulletins

Coal Creek flows from the west slope of the part of the Wasatch Mountain range which is located in the southeast part of Iron County, Utah. Its drainage area is almost 100 square miles.

Seasonal and daily stream-flow fluctuations are very pronounced. During the high water of spring the flow has reached more than 600 second-feet. At the time of high water, the daily fluctuations are the greatest. During the low water season in July and August, the flow has dropped as low as 12 second-feet since 1917, when accurate records were first kept; and, from the accounts of early …

Bulletin No. 182 - The Net Duty Of Water In Sevier Valley, Orson W. Israelsen, Luther M. Winsor

UAES Bulletins

The Sevier River is one of the most important sources of irrigation water in Utah. It rises in two main branches. The south fork rises in Kane County and flows almost due north to Junction in Piute County, where it joins the east fork, which rises partly in Garfield County and partly in Sevier County. The Garfield County branch of the east fork flows north, and the Sevier County Branch flows south to Coyote where the two tributaries join and flow westward into Junction. From Junction, the river flows northward past Marysvale, Sevier, Richfield, Salina, Gunnison, and Mills, where it …

Bulletin No. 173 - The Duty Of Water In Cache Valley, Utah, F. S. Harris

UAES Bulletins

The greater part of this bulletin is devoted to a report of experiments on the relation of the amount of irrigation water applied to the yield of crops. As the agriculture of Utah develops, it becomes more obvious each year that the chief factors limiting the production of crops is irrigation water. It is desirable, therefore, to have available all possible information on the subject. Water is so scarce that none should be wasted either directly or by attempting to spread it over so much land that it is not economically applied. Wasteful extravagance on the one hand and undue …

Circular No. 36 - Practical Information On The Measurement Of Irrigation Water, O. W. Israelsen

UAES Circulars

The economical use of water in irrigation depends primarily on water measurement. That significant advantages, public and private, attend the measurement of water delivered to individual irrigators has long been recognized in older irrigated countries. The rapidly increasing utilization of Utah's available water supply, the consequent increase in its value, and the tendency on the newer canal systems to base the annual irrigation charges on the amount of water used make an understanding of the methods of water measurement an absolute necessity. Furthermore, many irrigators now realize that the vast store of information concerning the relations of water, soils, and …

Bulletin No. 26 - Sub-Irrigation Vs. Surface Irrigation And Water For Irrigation, J. W. Sanborn, Samuel Fortier

UAES Bulletins

It has long been held that irrigation water applied beneath the surface is better than surface irrigation, in relation to the amount used, the temperature of the soil, the amount of evaporation, washing of soil and yield of crop, including quality of crop received. Though philosophically there would seem to be little doubt that the propositions are well taken, sub-irrigation as an economical process has been over-pres ed by some as a mean of very greatly curtailing the amount of water used . There are those who have asserted that only one-tenth of the water applied by sub-irrigation would be …
