Water levels in California's reservoirs have jumped from 28% of capacity to 58% of capacity in the span of one year (July 2015 - July 2016). While the 104% spike is a large gain, the State remains at little over half of full capacity.
Pictured below: July 2015 to July 2016 difference in CA Reservoir Water Storage as measured and reported by CA Department of Water Resources (DWR).
On the right is a map with the reservoirs reported on by DWR. The circles represent where each reservoir is located throughout the state. The size of the circle represents that size of the reservoir's capacity. The color represents that % of capacity of the reservoir for each month. The months can be filtered by using the Month, Year on the left side of the dashboard.
In the center is the average % of capacity of all reservoirs within each river basin. The thickness of the bar indicates the total capacity within the river basin and similar to the reservoir map, the color represents the average % of capacity within each river basin.
You can also filter by reservoir or river basin by using the filters on the left OR by clicking on an individual reservoir or river basin in visualization.
