Ground-water resources of the Paintrock irrigation project, Wyoming, with a section on the quality of the water
The ground-water conditions of the area covered by the Paintrock irrigation project, in north-central Wyoming, were investigated during the summer of 1947. The purpose of the study was to obtain a general evaluation of ground-water recharge, discharge, and storage in the area now irrigated and in the adjacent areas where additional lands are to be irrigated. Much of the area covered by this report consists of flat to gently sloping stream terraces and alluvial-bottoms along Nowood, Paintrock, and Medicine Lodge Creeks. The stream-terrace materials consist of fluviatile sand, clay, and gravel. The alluvium is very fine grained and in general has low permeability. The materials underlying the stream terraces and the bottomlands became progressively finer grained and less permeable downstream. The bedrock formations underlying the area studied range from the Madison limestone of Mississippian age to the Fort Union formation of Paleocene age. Beds have been folded into several prominent structures which trend northwest-southeast across the area. Several of the formations exposed in the area serve as aquifers and yield water to domestic and stock wells. The most important bedrock aquifers are the Fort Union, Lance, Meeteetee, Mesaverde, Frontier, Cloverly and Morrison formations , the Tensleep sandstone, the Amsden formation, and the Madison limestone. More than 7,000 feet of strata are exposed in the area, the older beds being exposed on the western flank of the Big Horn Range near the eastern end of the area. The quality of the water in the project ranges within wide limits. The concentration of dissolved solids in seven samples of ground water ranges from 279 parts per million for a water in the Tensleep sandstone to 4,590 parts per million for a water in the Morrison formation. The hardness as calcium carbonate (CaCO 3 ) ranges from 13 to 1,680 parts per million. Limited data on the quality of water in Nowood and Paintrock Creeks indicate that these waters are suitable for irrigation. The water in Paintrock Creek near Tensleep is higher in mineral content and hardness than the water upstream at Hyattville as a result of return flow of the irrigation water that is applied to farm lands above Tensleep.

Geology and ground-water hydrology of the Heart River irrigation project and the Dickinson area, North Dakota
The Heart River irrigation project, in southwestern North Dakota, lies in the Missouri Plateau section of the Great Plains physiographic province, which extends from the Missouri escarpment to and beyond the western border of the State. The area ranges in altitude from 1,620 to 2,275 feet and locally has strong relief. The floor of the Heart River Valley is underlain by alluvial deposits of Quaternary age. In the westernmost part of the areas the Fort Union formation of Paleocene (Tertiary) age forms the valley sides, but in a downstream direction the Cannonball and Ludlow formations, here undifferentiated, also of Paleocene age, crop out in the valley sides and underlie progressively broader areas of the upland surface. The Hell Creek formation of Upper Cretaceous age appears above stream level only in the stretch of the valley between the center of T. 136 N., R. 85 W., and the northeastern part of T.. 137 N., R. 84 W. Glacial Drift, which once covered the whole area, now has been almost entirely removed by erosion except for .scattered boulders on the uplands. The Cannonball and Ludlow unit and the Fort Union formation yield, moderate supplies of ground water, and the river alluvium yields more abundant supplies. At the present rate of withdrawal and with normal precipitation there is little danger of seriously depleting the supply. In 1946 the average depth to water in observation wells in the Heart River Valley was 19 feet, whereas the depth to water in observation wells in the upland averaged 30 feet. The Dickinson area is small and is about 45 miles upstream from the Heart River irrigation project. Ground-water levels in the Dickinson municipal well field have declined considerably within recent years, but the impounding of Heart River water is expected to insure a more adequate water supply for the town. Samples of ground water from four wells in the lower Heart River Valley were analyzed to determine the present mineral character of the waters in this region. Waters from shallow and deep wells in the Dickinson area were analyzed to assist in determining the practicability of further utilization of ground water as a public supply. A map showing areas of the least-mineralized ground water in the Dickinson area is presented and the need of further exploratory work is discussed.

Progress report: chemical character of surface waters in the Devils Lake Basin, North Dakota
Devils Lake in northeastern North Dakota was at one time the most popular summer resort in the state. With decline in lake level the lake has become a shallow body pf vary saline water, which scenic value and recreational appeal completely destroyed. Under the Missouri River development program, it is proposed to restore the lake level to an altitude of 1,425 feet by diversion of Missouri River water. The chemical character of the water in Devils Lake and in other surface bodies in Devils Lake Basin is determined from the analyses of 95 samples. The physical and chemical properties of lake bed deposits are also shown. Lake water in the basin vary considerable in both concentration and composition, ranging from fresh bicarbonate waters of 300 parts per million dissolved solids to sulfate waters of over 100,000 parts per million of soluble salts. Twenty-four samples indicates the chemical character of water in the Red River of the North and its tributaries. The probable concentration of dissolved solids in water of Devils Lake at altitude 1,425 feet has been estimated as ranging from 3,000 to 7,600 parts per million. Final concentration will largely depend upon the percentage of deposited salts reentering solution and the quality of the inflow water. The possible effects of lake effluents on downstream developments, with particular reference to sanitation and pollution problems, are also discussed in this report.

Progress report on the geology and ground-water hydrology of the lower Platte River Valley, Nebraska, with a section on the chemical quality of the ground water
The occurrence of abundant ground-water supplies in the lower Platte River Valley has made possible the present agricultural and industrial economy of the area. Likewise, the future development of the area is dependent on the wise use of this important resource. The current investigation, on which this report is based, is a necessary step in the planning for the greatest ultimate utilization of the water resources in the lower Platte River Valley. The area covered by this study is the floor of the lower Platte River Valley between North Platte and Fremont and embraces about 2,500 square miles. The entire valley floor is underlain by unconsolidated Pleistocene sediments which consist of clay, silt, sand and gravel and range in thickness from less than 20 feet to nearly 200 feet. Westward from Cozad these sediments were deposited in a valley entrenched in bedrock, but east of Cozad they are continuous with similar deposits which underlie the adjacent uplands. Bedrock formations of Tertiary age are in contact with the basal Pleistocene sediments from the west end of the area to about Central City. From Central City eastward, formations of Cretaceous age immediately underlie the Pleistocene deposits. The Pleistocene sediments and underlying pervious formations are water saturated below depths which range from less than 1 foot to about 90 feet below the surface. In general, the configuration of the water table is similar to the topography of the land surface, but the relief on the water table is considerably less by comparison. Movement of ground water is either toward the river or parallel to it. Based on present information, movement of ground water out of the valley is not indicated but additional water-level control is needed south of the valley between Grand Island and Columbus to determine the possibility of ground-water loss in this stretch of the valley. Periodic observations of water-table fluctuations have constituted an important phase of ground-water studies in the lower Platte River Valley. Examination of water-level data collected by the Geological Survey in cooperation with the Conservation and Survey Division of the University of Nebraska indicates that water levels throughout most of the valley between Gothenburg and Grand Island declined during the 9-year period, December 1930 to December 1939. The maximum net declines observed during this period were a little greater than 4 feet. During the period December 1939 to December 1946, water levels recovered throughout much of the same area; in local areas on the south side of the Platte River between North Platte and Overton water levels rose in excess of 10 feet as a result of seepage losses tram canals and irrigated lands. However, north of Wood River in western Hall County water levels continued to decline to the extent that in at least 3 observation wells water levels in December 1946 were more than 5 feet lower than in December 1930. Water levels were measured monthly in 1946 and bimonthly in 1947 in observation wells located throughout the area covered by this report. During this period water levels fluctuated through a range of about 3 feet, the lowest levels being reached in September 1946 and the highest levels being reached in July 1947. Average fluctuations between successive measurements were a little less than 0.4 foot. The amount of ground-water discharge in the summer months of 1947 was approximately double that of the previous summer. However, replenishment to groundwater storage during the fall of 1946 and the spring of 1947 was sufficiently great that the amount of water in storage in the valley as a whole at the end of the 2-year period was essentially equal to the amount in storage at the beginning of the period. At the end of 1947 the Dawson and Buffalo County areas showed gains to storage whereas the remainder of the valley suffered vary slight losses during the same 2 years. The quantity of ground water that a water-bearing material will yield is dependent upon the hydrologic properties of the material. Two hydrologic properties of greatest importance are permeability and specific yield. During the course of the present investigation 5 pumping tests were conducted to determine the coefficients of permeability and storage of the Pleistocene deposits. The values of the former range from 955 to 4,925 and the latter tram 0.007. to 0.236 attar 24 hours of pumping. The mineral character of the ground water has been determined from analyses of samples, of which 15 represented municipal supplies and 3 were irrigation waters. Ground waters analyzed for this report contained variable amounts of dissolved solids ranging from 240 to 1,060 parts per million, with hardness values above limits considered desirable tor public supplies. The increased concentration of dissolved solids for ground waters in the western part of the valley as a result of return flow conditions, is noted. Ground waters in the valley are discussed as to suitability for municipal and irrigation uses, and analyses of samples do not reveal any serious condition that would adversely affect the use of these waters for the purposes intended. As irrigation increases, periodic chemical analyses of ground waters in this area will be required to evaluate the effects of the re-use of drainage waters and to provide information for salinity control. Ground-water supplies are drawn upon extensively for irrigation purposes, for municipal supplies, and for rural, domestic and stock supplies. Nearly 4,000 irrigation wells are known to exist in the area, the greatest concentrations of these being in Dawson, Buffalo, and Hall Counties.

Geology and ground-water hydrology of the Angostura irrigation project, South Dakota, with a section on the mineral quality of the waters
The lands to be irrigated from water stored in the Angostura Reservoir are situated on the lover of two terraces along the southeast side of the Cheyenne River in northeastern Fall River County and on the terrace known as Harrison Plat in southeastern Custer County, S. Dak. The terrace deposits are composed of relatively permeable sands and gravels that rest on a shale bedrock platform. The terrace surfaces are mantled in part by slope wash derived from higher shale slopes and by wind-blown sand. Ground water occurs under water-table conditions in the river alluvium and in terraces above the river. Although the zone of saturation in the terrace deposits is 6enerally thin, it is essentially continuous in the area southeast of the river, and the water issues as springs in the terrace faces along the inner valley of the river and along the valleys of tributary streams cuttin6 back into the terraces. A zone of saturation is present only in part of the Harrison Plat area, and it extends to the terrace face only along Cottonwood Creek. Wells in the unconsolidated mantle rock supply water for domestic and stock purposes, but yields are small. Abundant supplies of artesian water are available at depths ranging up to 3,000 feet but are not now utilized except at the extreme western end of the area where the bedrock aquifer is close below the surface. The effect of applying irrigation water on the terrace lands will depend on the character of the underlying material and on the measures taken to forestall waterlogging and other undesirable effects. Terrace areas that are mantled by slope wash will be especially susceptible to waterlogging, as will valley-bottom areas mantled by colluvium that are adjacent to irrigated terracea. Periodic measurements of water levels in observation wells will give warning of potential waterlogging in time to permit taking preventive measures. Analyses of samples of both ground water and surface water indicate a high mineral content. In general, samples from the Cheyenne River are higher in total dissolved solids and lower in percent sodium than the ground water.
