Real-Time Ground-water Sites

Real-time sites - Current-conditions data transmitted from selected ground-water sites. Values in pop-up bubbles are updated hourly. Additional data for real-time sites.

Field water-level measurements - Manual measurements of depth to water in wells. These measurements are often used to supplement and (or) verify the accuracy of the instantaneous measurements. Selected sites with at least 10 measurements are included in these maps. The last value available is shown in the pop-up bubble for each site. Because of the large number of sites available the sites have been broken up into three regions. All of California is available but not recommended for slower internet connections. Addtional data for ground-water sites.
