Show Great Variations Found To Exist In Ground Water A recent summary of groundwater ground-water conditions in Utah was made by G. H. Taylor and H. E. Thomas, of the United States geological survey, department of the interior, in cooperation with the state engineer of Utah. During 1936 about 2,300 periodic measurements cf wate- levels were made in 3o0 observation wells, and about 1,400 measurements were made in 500 miscellaneous wells. This summary indicates that ground-water levels in most of the more notable ground-water areas stood higher in the fall and winter of 1936 than in the corresponding period of 1935. The average rise in groundwater ground-water levels was greatest in areas along the western base of the Wasatch mountains. The rise in the Utah Lake valley averaged 5.0 feet, and in tihe Juab valley, Davis county, the eastern part of Box-elder Box-elder county, and the Ogden, Cache and Sanpete valleys it was between be-tween 3.9 and 4.6 feet. The water level declined in a few wells in some of these areas, but the decline de-cline was generally restrioted to wells rather distant from areas of ground-water recharge. The average ave-rage rise of ground-water in the Jordan river valley was 2 feet; in the lower part of Weber county, 1 foot; in the central Sevier valley, 0.8 foot; in the upper Sevier valley, val-ley, 0.4; in the Pavant valley, 3 feet; and in the Beaver valley, 2 feet. The rise in water levels in 12 observation wells in the Milford pumping district, Beaver county, average 0.7 foot. Only in the Cedar City valley, Iron county, did the water level in all observation wells decline. The average decline in 9 wells was 1.8 feet, and the greatest individual decline was 3.1 feet. In the Tooele valley the water levels in 11 wells declined an average of 0.6 foot. In the Escalante valley, Iron and Washington counties, including the Beryl district, 12 wells declined an average of 0.1 foot. Water levels i in wells in the Parowan valley district stood about the same in 1936 as in 1935. The water levels in 10 widely distributed wells in the Uinta basin rose an average of 3 feet. J Fluctuations of water levels in ' these wells ranged from a net rise cf 16.4 feet to a net decline of 0.4 foot. In the Sevier desert, in the vicinity of Delta, 12 wells showed : an average rise of 0.1 foot. The rather general rise in i ground-water levels indicates that j recharge to ground-water basins j in L"tah, most of which are artesian, arte-sian, has been greater during the past year than the discharge. This has been caused in part by increas-i increas-i ed precipitation and in part by the ' adoption of conservation measures j consisting chiefly of the control of i waste water from artesian wells. t n |
