These before and after pics offer a comparison of the Californian landscape and show how two reservoirs have been affected. The first photo is the lake at almost 100% capacity and the second photos shows it at only 17%.
Below you can see the current conditions of California's major reservoirs compared to the historical average for Feb 27. Notice how recent rain storms have provided some relief since January, helping to boost Folsom Lake to 30% of its total capacity. But all reservoirs are still in the red compared to what's normal for this date.
