  "description": "This data set consists of digital polygons of a constant\nrecharge value for the alluvial and terrace deposits along the\nNorth Canadian River from Canton Lake to Lake Overholser in\ncentral Oklahoma. Ground water in approximately 400 square miles\nof Quaternary-age alluvial and terrace aquifer is an important\nsource of water for irrigation, industrial, municipal, stock,\nand domestic supplies. The aquifer consists of clay, silt,\nsand, and gravel. Sand-sized sediments dominate the poorly\nsorted, fine to coarse, unconsolidated quartz grains in the\naquifer. The hydraulically connected alluvial and terrace\ndeposits unconformably overlie Permian-age formations. The\naquifer is overlain by a layer of wind-blown sand in parts of\nthe area.\nA uniform recharge rate of 1 inch per year was used as input to\nthe ground-water flow model for the aquifer and is used in this\ndata set.\nThe features representing boundaries along geological contacts\nwere extracted from published digital surficial geology data\nsets based on a scale of 1:250,000. The northwest and southeast\ngeographic limits of the aquifer and were digitized from a\nfolded paper map in a ground-water modeling report, at a scale\nof 1:250,000\nGround-water flow models are numerical representations that\nsimplify and aggregate natural systems. Models are not unique;\ndifferent combinations of aquifer characteristics may produce\nsimilar results. Therefore, values of recharge used in the\nmodel and presented in this data set are not precise, but are\nwithin a reasonable range when compared to independently\ncollected data.",
