U.S. Geological Survey 2009 vector digital data http://water.usgs.gov/lookup/getspatial?sim2993_water_table Janet M. Carter and Allen J. Heakin 2008 map Scientific Investigations Map 2993 Reston, VA U.S. Geological Survey http://pubs.usgs.gov/sim/2993/ This data set describes the water-table contours that were used to create a map of the generalized potentiometric surface of the Arikaree aquifer in the Pine Ridge Indian Reservation and Bennett County. The contours were based on water levels in wells completed in the Arikaree aquifer that were measured between 1929 and 2006. This data set was created as part of a project to map the potentiometric surface of the Arikaree aquifer in the Pine Ridge Indian Reservation and Bennett County. In 1998, the U.S. Geological Survey began working in cooperation with the Oglala Sioux Tribe to develop a potentiometric map of the Arikaree aquifer in Jackson and Shannon counties. In 2003, the study area was expanded to include Bennett County. This data set was subjected to the same review standard that applies to all U.S. Geological Survey publications. Reviewers were asked to check the topological consistency, tolerances, attribute frequencies and statistics, projection, and geographic extent. The reviewers checked the metadata files for completeness and accuracy. Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in nonproprietary form, as well as in ARC/INFO format, this metadata file may include some ESRI ArcInfo Coverage specific terminology. 1929 2006 ground condition Complete None planned -102.785798 -101.191684 43.662501 42.964815 None Arikaree aquifer water table potentiometric surface hydraulic head inlandWaters None Pine Ridge Indian Reservation Bennett County Shannon County Jackson County South Dakota None Arikaree Formation None Tertiary None These data should not be used at scales larger than 1:125,000.

Public Unclassified None Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 3; ESRI ArcCatalog 9.3.1.1850 Chain-node topology present. Multiple visual checks were done to verify that the attribute data were coincident with the original source map (SIM 2993). A visual check of the contours was made against the original source map.

STEP 1: Hydraulic heads available from wells and springs were plotted on a mylar sheet and hand contoured. STEP 2: The mylar map containing the hand-drawn contours was scanned and the image file was registered. STEP 3: Line work was extracted using image processing techniques and verified and edited using the rectified image file as the background. 20090223 Janet Carter U.S. Geological Survey Hydrologist mailing and physical address
