  <dc:description>&lt;p&gt;The High Plains aquifer in Oklahoma is part of a region~l aquifer&lt;br&gt;system extending from South Dakota on the north through Wyoming, Colorado,&lt;br&gt;Nebraska, Kansas, and Oklahoma to Texas and New Mexico o~ the south.&lt;br&gt;(index map). The principal aquifer, the Ogallala F?rmat1on of :ert1ary&lt;br&gt;age, is hydraulically connected with other unconsolidated ~eposits, .&lt;br&gt;principally of Quaternary age. Alluvium and terrace dep?sits htdrau]ically&lt;br&gt;connected with the Ogallala are included in the High Pla1ns.aqu1fer in&lt;br&gt;Oklahoma. Parts of the underlying bedrock also are hydraul 1cally connected&lt;br&gt;with the Ogallala. The High Plai ns aquifer in Oklahoma has been&lt;br&gt;removed by erosion on the west exposing underlying rocks of Cretaceous&lt;br&gt;age and on the east exposing rocks of Permian age.&lt;/p&gt;</dc:description>
