Ogallala formation

The Ogallala formation of Pliocene age, which under lies most of the upland, yields moderate quantities of water to wells in an area west of the city of Cheyenne. East of Cheyenne, the saturated thickness of the Ogallala forma tion is not sufficient for that formation to yield large quantities of water to wells, but ...What remains in the Ogallala formation is mostly fossil water drawn from the Rockies long ago. There is no massive and perpetual recharge (today it is a paltry inch-a-year trickle down) for most recent geological history. The High Plains aquifer is like a flat, sandy beach where the tide has recently gone out; no new water comes in at the upper ...

Oct 20, 2023 · Ogallala formation. Calcareous grit or soft limestone, sandy clay, and sand, with basal conglomerate at many places. Of late Tertiary (Pliocene?) age. Thickness 150 to 300 feet. Unconformably underlies EQUUS beds and unconformably overlies Arikaree formation. Extends from Kansas and Colorado far into Nebraska. Rests (usually conformably) on Gering formation, where that formation is present; where Gering is absent, on Brule clay. There is possibility upper member of Gering formation may be basal part of Arikaree formation. The Arikaree enters Nebraska from Wyoming, and thins out beneath Ogallala formation in eastern part of Banner County.general and also what is known about the Ogallala specifically in the southern Nebraska Panhandle and adjacent areas where N.H.

The Ogallala Formation, Pleistocene deposits, and alluvium combine to form the High Plains aquifer. Water Resources in the High Plains Aquifer. Usable water in the High Plains aquifer is in the pore spaces between particles of sand and gravel. This water (called groundwater) accumulated slowly--in some of the deeper parts of the aquifer, over ...Pliocene Ogallala Formation of Trego County, Kansas may be referable to Regina.

Groundwater depletion, a term often defined as long-term water-level declines caused by sustained groundwater pumping, is a key issue associated with groundwater use. Many areas of the United States are experiencing groundwater depletion.The Ogallala Formation is the primary aquifer in the High Plains Aquifer system.
