资源简介：
This data set describes ground-water regions in the United
States defined by the U.S. Geological Survey. These
ground-water regions are useful for dividing the United States
into areas of roughly similar hydrologic characterstics and
water-use patterns. These regions are very generalized and
were developed from a illustration published at a scale of
approximately 1:20 million.
本数据集描述了由美国地质调查局（U.S. Geological Survey）划定的美国境内地下水区域。此类地下水区域可用于将美国划分为水文特征与用水模式大致相似的多个分区。该类区域属于高度概化的划分结果，其编制依据为一幅比例尺约为1:2000万的公开图示。
