Aquifer Boundary of the Wood River Valley Aquifer System, South-Central Idaho

This dataset contains the boundary of the Wood River Valley aquifer system as modified and expanded from that defined by Skinner and others (2007): It has been extended farther up several tributary canyons, extended up the Big Wood River to include a number of wells near the mouth of Baker Creek, expanded to include the western side of the Poverty Flat area, and extended slightly downstream of Stanton Crossing and Picabo. Although most of the boundary delineated by Skinner and others (2007) has been retained here, modifications were made in places to include information from additional wells that penetrated bedrock below alluvium.This dataset was created in support of the third phase of a continuing U.S. Geological Survey (USGS) study to assess the groundwater resources of the Wood River Valley, south-central Idaho. The first phase was documented in "Water-resource trends and comparisons between partial development and October 2006 hydrologic conditions, Wood River Valley, south-central Idaho" (Skinner and others, 2007), and the second phase was documented in "Ground-water budgets for the Wood River Valley aquifer system, south-central Idaho"(Bartolino, 2009). The third phase is a description of the hydrogeologic framework of the Wood River Valley aquifer system. The Wood River Valley contains most of the population of Blaine County and the cities of Sun Valley, Ketchum, Hailey, and Bellevue. This mountain valley is underlain by the alluvial Wood River Valley aquifer system. The entire population of the area depends on groundwater for domestic supply and rapid population growth since the 1970s has caused concern about the long-term sustainability of the groundwater resource.

本数据集包含基于Skinner等人（2007）划定的边界经修改与扩展的伍德河谷（Wood River Valley）含水层系统边界。本次扩展内容包括：向多条支流峡谷上游延伸范围、沿大伍德河（Big Wood River）向上延伸以纳入贝克溪（Baker Creek）河口附近的多口井、扩展至覆盖贫困平原（Poverty Flat）区域西侧，以及略微向斯坦顿渡口（Stanton Crossing）与皮卡博（Picabo）下游方向延展。尽管本数据集保留了Skinner等人（2007）划定的绝大多数边界，但在部分区域纳入了穿透冲积层下伏基岩的额外钻井数据以完成修订。

本数据集为支持美国地质调查局（U.S. Geological Survey, USGS）正在持续开展的爱达荷州中南部伍德河谷地下水资源评估研究的第三阶段而构建。该研究的第一阶段成果记载于《爱达荷州中南部伍德河谷部分开发与2006年10月水文条件间的水资源趋势与对比》（Skinner等人，2007），第二阶段成果记载于《爱达荷州中南部伍德河谷含水层系统地下水均衡》（Bartolino, 2009）。第三阶段的研究内容为伍德河谷含水层系统的水文地质框架描述。

伍德河谷涵盖了布莱恩县（Blaine County）的大部分人口以及太阳谷（Sun Valley）、凯彻姆（Ketchum）、海利（Hailey）与贝尔维尤（Bellevue）等城镇。该山间河谷的地下赋存冲积成因的伍德河谷含水层系统。本区域全体人口均依赖地下水作为生活供水来源，而自20世纪70年代以来的快速人口增长已引发了人们对地下水资源长期可持续性的担忧。
