There are at least seven major aquifer systems in Nebraska. By far, the High Plains/Ogallala aquifer is the largest in terms of volume of water in storage and withdrawals for irrigation. Several secondary aquifers exist in areas outside of the High Plains aquifer, providing water for irrigation, municipal supplies, and domestic use in parts of far western and far eastern Nebraska.The Ogallala Aquifer is a massive underground reservoir that lies beneath much of the High Plains region. The aquifer extends 175,000 square miles across eight states, including parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas and Wyoming. In many instances, the aquifer is the main source of water for both ...Graphic sections of the Ogallala Formation, Ellis, Roooks Counties, Kansas Available as an Acrobat PDF file, 1.2 MB Please Note.

One of the best vertically continuous exposures is in the west side of the roadcut at the ridge called Devils Backbone, which is located in the NW¼, NE¼, Sec.25, T.16S., R.32W.

We use the stable isotopes of oxygen (δ18O) as preserved in authigenic carbonates hosted within the abundant paleosol and fluvial successions that comprise the Ogallala Formation as a record of ...These calcareous soils form the hard and durable caprock horizons that cover much of the Southern High Plains. Geologists have included these deposits within the Ogallala Formation or Group. These strata comprise the majority of sediments in the High Plains aquifer, the primary source of groundwater in the Southern and Central Great Plains."The Ogallala formation is believed to be a stratigraphic unit and to be continuous from the type locality near Ogallala station in western Nebraska .. ." Elias (1931, p. 135) remeasured the beds outcropping northeast of Ogallala, Nebraska, and gave corrected footages. Hibbard (1933) and Hesse (1935) were first to report the oc- ...The Ogallala formation is the main rock unit of the High Plains Aquifer and is named after the town of Ogallala in southwestern Nebraska where the rock is exposed at the surface. It is comprised of clay, silt, sand and gravel that were deposited in streams that drained from the Rocky Mountains during the late Tertiary geologic time period ...

The formation of the Ogallala Aquifer started 24 million years ago, and ended 1.8 million years ago, according to an MIT Mission 2012 Clean Water report. This happened as sand and gravel that had eroded from the Rocky Mountains were carried eastwards by large rivers, and these sediments ended up covering the Great Plains landscape.The southern High Plains of Colorado, an area of about 2,800 square miles in the southeastern part of the state, is underlain by the Ogallala Formation of late Tertiary age, The southern High Plains of Colorado extend from the Colorado State line on the east and the ans south to the edge of the Ogallala Formation on the north and west. The Ogallala Formation is an unconsolidated or partly ... ….

The silicified rocks of the Ogallala formation are grouped, on the basis of their texture, color, degree of cementation, and predominant lithology of the original deposit, into two major categories--here termed quartzite and chert--and several special types of minor extent and importance. ... The Ogallala quartzite in the region north of Texas ...Dec 28, 2006 · The northern boundary of the Raton section is placed somewhat indefinitely at the northern limit of the area injected by igneous dikes. The eastern boundary of the Raton section is at the eastern margin of the lavas of Mesa de Maya and adjoining mesas, where lava-capped outliers of Ogallala Formation are separated from the Ogallala of the High Plains only by the canyon of Carrizo Creek.

The Loup Fork formation of Hayden, Leidy, Marsh, Cope and in part of Scott, Hatcher arid Osborn, may be regarded as corresponding to the Ogallala of Darton. To this formation, also, belongs the Republican river formation of Osborn (1910, p. 348) and part of the Snake creek formation of Cook and Matthew (1924).Ogallala Formation, and locally it is as much as 27 thick. The eolian sedinents generally are finer grained to the northeast, indicating that they were derivedOgallala formation often sits directly on top of consolidated sediments, which are more than 250 million years old. In Cimarron and western Texas counties, a younger formation of shale and sandstone called the Dockum group overlies the redbed. Other formations, including the Dakota Sandstone and Morrison Formation, also are found in the Oklahoma

The Kimball Clayton South …The Ogallala Formation consists mostly of coarse sedimentary rocks in its deeper sections, which transition upward into finer-grained material. The water-saturated thickness of the Ogallala Formation ranges from a few feet to more than 1,000 feet. Its deepest part is 1200 ft. (300 m) and is generally greater in the Northern Plains. [10] small boats for sale on craigslistoya symbol The Ogallala Formation has a thickness from 0 to approximately 800 feet, with an average saturated thickness of 95 feet . Throughout most of the Ogallala Aquifer area, withdrawal of water has exceeded the recharge rate. Water levels have declined in excess of 300 feet in the last 50 to 60 years. The use of groundwater from the Ogallala is ...The Oklahoma Panhandle and adjacent areas in Texas, Kansas, Colorado, and New Mexico have prospered because of the development of supplies of fresh water and of oil and gas. The Ogallala and, in places, Cretaceous rocks produce fresh water for irrigation, public supply, and domestic and stock use through approximately 9,000 irrigation and public supply wells and a large but undetermined number ... nsp zelda tears of the kingdom outcrops of the Ogallala Formation, which is an important underground aquifer throughout the High Plains. Here at Scott Lake, the Ogallala crops out at the surface as hard, dense sandstones cemented with calcium carbonate, known locally as mortar beds.
