Galloway 1999 Open-File Report 99-602 Rapid City, SD U.S. Geological Survey This dataset describes springs in the Black Hills area that were used to create potentiometric surface maps for the Inyan Kara, Minnekahta, Minnelusa, Madison, and Deadwood aquifers. This data set was created as part of the Black Hills Hydrology Study (BHHS). The BHHS is a long-term investigation that was initiated in 1990 as a cooperative effort between the U.S. Geological Survey (USGS), the South Dakota Department of Environment and Natural Resources (DENR), and the West Dakota Water Development District. West Dakota represents various local and county cooperators. The purpose of the study is to assess the quantity, quality, and distribution of surface and ground water in the Black Hills area of western South Dakota (Driscoll, 1992). The study area includes parts of Butte, Custer, Fall River, Lawrence, Meade, and Pennington counties in South Dakota. 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. The reviewers checked the metadata and a_readme.1st files for completeness and accuracy. Related_Spatial_and_Tabular_Data_Sets: Potentiometric contours for the Deadwood, Madison, Minnelusa, Minnekahta, and Inyan Kara aquifers (ddwdpcon, mdsnpcon, mnlspcon, mnktpcon, inkrpcon) and data set of wells with water-level information for each aquifer (ddwdpwpt, mnlspwpt, mdsnpwpt, mnktpwpt, inkrpwpt). Also, surficial hydrogeology in the Black Hills study area (hydrogeo).

Rapid City South Dakota 57702 USA 1-888-275-8747 (605) 355-4523 (jgallowa@usgs.gov) Compilation of this data set and the associated metadata was funded in cooperation with the South Dakota Department of Environment and Natural Resources and the West Dakota Water Development District. SunOS, 5.6, sun4u UNIX ARC/INFO version 8.0.1 Multiple visual checks were done to verify that the attribute data was coincident with the original source information. Point features present. This data set consists of spring locations for the Inyan Kara, Minnekahta, Minnelusa, Madison, and Deadwood aquifers in the Black Hills, South Dakota. Points were plotted on mylar and checked for accuracy using 1:24,000 topographic maps.

Initial latitude and longitude for each spring were obtained through location plotting on and interpolation from USGS 1:24,000 topographic maps. 19980724 Coordinates for each site were used as data input for creating a point coverage in ARC/INFO. Attribute information was then added to the point coverage. 19980724 First draft of metadata created by gjarrell using FGDCMETA.AML ver. 1.33 07/15/99 on ARC/INFO data set /home/student/gja/meta/spngppt 20000424 Point Point 108 Universal Transverse Mercator 13 0.9996 -105.00 0.00000 500,000 0.0000 coordinate pair 1.0 1.0 Meters North American Datum of 1927 Clarke 1866 6378206.4 294.98 > >SPNGPPT.PAT: > >COLUMN ITEM NAME WIDTH OUTPUT TYPE N.DEC ALTERNATE NAME > 1 AREA 8 18 F 5 > 9 PERIMETER 8 18 F 5 > 17 SPNGPPT# 4 5 B - > 21 SPNGPPT-ID 4 5 B - > 25 SITE_ID 15 15 C - > 40 LOCAL 13 13 C - > 53 ALTITUDE 4 4 I - > 57 DISCHARGE 8 8 F 2 > 65 AQUIFER 7 7 C - All of these items were retrieved from the USGS Ground Water Site Inventory data base, except for AREA, PERIMETER, <COV>#, <COV)-ID. ------------------------------------------------------------ AREA: Area of the point (assigned zero). PERIMETER: Perimeter of the point (assigned zero). SPNGPPT#: An ARC/INFO generated internal feature identity number. SPNGPT-ID: User-assigned feature identity number. SITEID: This is a unique number given to each well. SITEID is a combination of the latitude and longitude of the well, plus a sequence number for wells located at the same latitude and longitude. (Note: The latitudes or longitudes originally assigned to sites in GWSI occasionally are determined to be incorrect. In these cases, the latitude or longitude is corrected, but the station identification number generally remains unchanged. Thus, the latitude or longitude for an occasional site may not correspond exactly with the station identification number). LOCAL This is a unique number based on the Federal land-survey system for western South Dakota. LOCAL consists of the township number followed by "N" or "S" (north or south of the Black Hills Baseline), the range number followed by "E" or "W" (east or west of the Black Hills Meridian), and the section number, followed by a maximum of four uppercase letters that indicate, respectively, the 160-, 40-, 10-, and 2.5-acre tract in which the site is located. These letters are assigned in a counterclockwise direction beginning with the letter "A" for the northeast quarter. A serial number following the last letter is used to distinguish between wells located in the same 2.5-acre tract. ALTITUDE: This is the elevation of the spring in feet above sea level. DISCHARGE: This is the volumetric discharge of the spring in gallons per minute. A negative value of -99.99 is used when discharge is unknown. AQUIFER: This is a code identifying the principal hydrologic unit that is contributing ground-water flow to the spring. The codes are as follows. When a spring has multiple aquifer sources, it is included under each. > AQUIFER hydrologic unit > > INKR Inyan Kara Aquifer > MNKT Minnekahta Aquifer > MNLS Minnelusa Aquifer > MDSN Madison Aquifer > DDWD Deadwood Aquifer none U.S. Geological Survey Ask USGS - Water Webserver Team mailing
