Minimum Depth to Groundwater for the Coastal San Francisco Bay Area

This dataset shows estimated values for minimum depth to groundwater in the coastal Bay Area. The estimation is based on an interpolation that uses ground elevation data and minimum depth to water values measured at monitoring wells in the nine Bay Area counties over the past 20 years.

NOTE: The most recently uploaded data file (August 24, 2018) has the highest accuracy in the interpolation. Please use this file rather than the older versions.

本数据集涵盖沿海湾区地下水位最小埋深的估算结果。本次估算采用插值方法，数据源为近20年间湾区9个县内监测井采集的地面高程数据与实测地下水最小埋深值。

注意：2018年8月24日上传的最新数据文件插值精度最优，请优先使用该文件而非旧版本。
