How dry is it?

The California Department of Water Resources has three graphs showing the water content of snow in California (northern, central, and southern) - here's the southern graph:
Snow pack water content - southern California - 2012
(click to see all three graphs)
The solid pink line creeping along near the bottom is the current water content. The broken brown line near it is the dry winter of 1976-77. The green line is last winter. The dotted black line smoothly arcing through the middle is the average - of all years, I suppose. The vertical scale is percentage, using the average water content on April 1 as 100%.
