The Vamoosa-Ada aquifer is an important source of water that underlies about 2,320-square miles of parts of Osage, Pawnee, Payne, Creek, Lincoln, Okfuskee, and Seminole Counties. Approximately 75 percent of the water withdrawn from the Vamoosa-Ada aquifer is for municipal use. Rural domestic use and water for stock animals account for most of the remaining water withdrawn. The Vamoosa-Ada aquifer is defined in a ground-water report as consisting principally of the rocks of the Late Pennsylvanian-age Vamoosa Formation and overlying Ada Group. The Vamoosa-Ada aquifer consists of a complex sequence of fine- to very fine-grained sandstone, siltstone, shale, and conglomerate interbedded with very thin limestones. The water-yielding capabilities of the aquifer are generally controlled by lateral and vertical distribution of the sandstone beds and their physical characteristics. The Vamoosa-Ada aquifer is unconfined where it outcrops in about an 1,700-square-mile area. The water-level elevation contours were digitized from a mylar map, at a scale of 1:250,000, used to publish a plate in a ground-water report about the Vamoosa-Ada aquifer. The water-level elevation contours in this data set extend west of the aquifer outcrop to areas where Vanoss Group rocks overlie the Ada Group. The data set also includes a water-level elevation contour for a terrace deposit east of the aquifer outcrop near the North Canadian River. Water-level elevations range from 800 to 1,000 feet above sea level for the Vamoosa-Ada aquifer. This data set was created for a project to develop data sets to support ground-water vulnerability analysis. The objective was to create and document a digital geospatial data set from a published report or map, or existing digital geospatial data sets that could be used in ground-water vulnerability analysis. Introduction -- This data set consists of digitized water-level elevation contours for the Vamoosa-Ada aquifer in east-central Oklahoma. The Vamoosa-Ada aquifer is an important source of water that underlies about 2,320-square miles of parts of Osage, Pawnee, Payne, Creek, Lincoln, Okfuskee, and Seminole Counties. Approximately 75 percent of the water withdrawn from the Vamoosa-Ada aquifer is for municipal use. Rural domestic use and water for stock animals account for most of the remaining water withdrawn. The Vamoosa-Ada aquifer is defined in a ground-water report as consisting principally of the rocks of the Late Pennsylvanian-age Vamoosa Formation and overlying Ada Group. The Vamoosa-Ada aquifer consists of a complex sequence of fine- to very fine-grained sandstone, siltstone, shale, and conglomerate interbedded with very thin limestones. The water-yielding capabilities of the aquifer are generally controlled by lateral and vertical distribution of the sandstone beds and their physical characteristics. The Vamoosa-Ada aquifer is unconfined where it outcrops in about an 1,700-square-mile area (D'Lugosz and others, 1986). The Vamoosa Formation is underlain by the Tallant and Barnsdall Formations in the northern part of the aquifer and the Hilltop and Belle City Formations in the southern part of the aquifer. The Ada Group in overlain by the Vanoss Group. The Vamoosa-Ada aquifer is overlain by alluvial and terrace deposits in some parts of the aquifer (Cederstrand, 1996a, 1996b, 1996c). In this report, elevation refers to distance above sea level and sea level refers to the National Gedodetic Vertical Datum of 1929 (NGVD29)--a geodetic datum derived from a general adjustment of the first-order level nets of both the United States and Canada, formerly called Sea Level Datum of 1929. The water-level elevation contours in this data set were digitized from a mylar map used to publish plate 3, "Map-A, Water-Table Surface in Unconfined Part of Aquifer," by D'Lugosz and others (1986), at a scale of 1:250,000. The water-level elevation contours in this data set extend west of the aquifer outcrop to areas where Vanoss Group rocks overlie the Ada Group. The data set also includes a water-level elevation contour for a terrace deposit east of the aquifer outcrop near the North Canadian River. Water-level elevations range from 800 to 1,000 feet above sea level for the Vamoosa-Ada aquifer. Reviews Applied to Data -- This electronic report was subjected to the same review standard that applies to all U.S. Geological Survey reports. Reviewers were asked to check the topological consistency, tolerances, attribute frequencies and statistics, projection, and geographic extent. Reviewers were given digital data sets and paper plots for checking against the source maps to verify the linework and attributes. The reviewers checked the metadata and a_readme.1st files for completeness and accuracy. Related Spatial and Tabular Data Sets -- This data set is one of four digital map data sets being published together for this aquifer. The four data sets are: > aqbound - aquifer boundaries > cond - hydraulic conductivity > recharg - aquifer recharge > wlelev - water-level elevation contours Digital map data sets of the Oklahoma surficial geology digitized from 1:250,000-scale maps (or 1:125,000-scale maps for the three Oklahoma panhandle counties) are published separately.

Water-level elevation contours represented at this scale are indicative of broad, regional trends and should not be interpreted as site specific. The water-level elevation contours were digitized from a mylar map (40 inches by 13 inches) with a maximum registration root-mean-squared error (RMSE) of 0.012 map inches (0.030 map centimeters) or 243 feet (74 meters) ground distance.

This data set includes all of the water-level elevation contours published by D'Lugosz and others (1986), plate 3, Map-A. D'Lugosz and others (1986) included areas near the eastern edge of the Vamoosa Formation that may be hydraulically connected with the aquifer. One such area in T. 11 N., R. 08 E. has an elevation value of 900 feet (D'Lugosz and others, 1986) and is east of outcrops of the Vamoosa Formation and Ada Group (Cederstrand, 1996c). D'Lugosz and others (1986) included water-level elevation contours for areas west of the outcrop area of the Vamoosa-Ada aquifer where Ada Group rocks are overlain by the Vanoss Group. None 64 meters Resolution as reported None. The map showing the water-level elevation contours in the Vamoosa-Ada aquifer was digitized from a mylar map, at a scale of 1:250,000, in a Transverse Mercator map projection with a central meridian of 97 degrees west longitude (D'Lugosz and others, 1986, plate 3, Map-A). The 1:250,000-scale U.S. Geological Survey quadrangle maps: Ardmore, 1967; Enid, 1965; and Oklahoma City, 1968; were used to register the water-level map with nine tics located across the center of the aquifer outcrop with a maximum root mean square error (RMSE) of 0.012 map inches (0.030 centimeters) or 243 feet (74 meters) ground distance. The water-table elevation contours west of the aquifer outcrop were included in this data set as shown in D'Lugosz and others (1986, plate 3, Map-A). 1996 Vector Point String 74 GT-polygon composed of chains Albers Conical Equal Area 29.5 45.5 -96 23 0.0 0.0 coordinate pair 64 meters 64 meters METERS North American Datum of 1983 Geodetic Reference System 80 6378137 298.257 WLELEV.AAT Arc attribute table ARC/INFO - Arc attribute table ARC/INFO - n/a n/a FNODE# Internal number of from-node Computed Sequential unique positive integer n/a n/a TNODE# Internal number of to-node Computed Sequential unique positive integer n/a n/a LPOLY# Internal number of polygon to left of arc Computed Sequential unique positive integer n/a n/a RPOLY# Internal number of polygon to right of arc Computed Sequential unique positive integer n/a n/a LENGTH Length of arc in coverage units Computed Positive real numbers n/a n/a WLELEV# Internal feature number Computed Sequential unique positive integer n/a n/a WLELEV-ID User-assigned feature number User-defined Integer n/a n/a ELEV Water-surface elevation in feet above NGVD29 'D''Lugosz and others (1986)' 800 1,000 LTYPE Line type 'D''Lugosz and others (1986)' 1 1 = solid line n/a MAJOR1 Water-surface elevation in feet above NGVD29 'D''Lugosz and others (1986)' 800 1,000 MINOR1 Line type 'D''Lugosz and others (1986)' 1 1 = solid line n/a Two attributes are associated with each line in this digital data set. The first attribute, ELEV, contains the elevation of the water-level contour, expressed in feet above the National Geodetic Vertical Datum of 1929 (NGVD29). The second attribute, LTYPE, contains the code, 1, indicating the line is solid on the source map. ELEV is stored in the first major code (MAJOR1) for lines, and LTYPE is stored in the first minor (MINOR1) code in the Digital Line Graph (DLG) version of this data set. See overview.
