Real-Time Lake Storage Sites

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

Field measured streamflow and lake sites - Periodic manual measurements of streamflow and gage height at streamflow and lake sites. These measurements are often used to supplement and (or) verify the accuracy of the time-series measurements. The last value available is shown in the pop-up bubble for each site. Additional data for surface-water sites.

Data are provisional and subject to revision.
