This weekend’s atmospheric river brought record-breaking amounts of rain to drought-plagued California. But they didn’t give the state’s water supply much of a boost, data shows.

The state Department of Water Resources compared the amount of water in select reservoirs across the state as of midnight Oct. 25 to the capacity of each reservoir and to historic levels for the same date. The data shows that, even after all of Sunday and Monday’s rainfall, many of California’s largest reservoirs are still holding less water than the historic level for this time of year.
