Water-table contours for the Arikaree aquifer, Pine Ridge Indian Reservation and Bennett County, South Dakota

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. 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.

本数据集发布于美国地质调查局（USGS）《科学数据审核、批准与发布政策》2016年10月1日生效日期之前，该政策详见USGS《调查手册》第502.8章《基础科学实践：科学数据发布的审核与批准》。本数据集收录了用于绘制松岭印第安保留地与贝内特县境内阿里卡里含水层（Arikaree aquifer）广义测压水面图的地下水位等值线。该等值线基于1929年至2006年间，对完钻于阿里卡里含水层的水井所测得的地下水位数据编制而成。
