While we've had a couple of years of OK rainfall, California appears to be heading into fairly extreme drought conditions, and the long term forecasts are currently bad. You can check out the US Drought Monitor, which includes a Long Term Drought Prediction graphic. There's also the California Department of Water Resources, which manages a page of California Reservoir Graphs. Looking at the page, you can see that most major reservoirs are well below average capacity. If you click on the reservoir names, you'll get a detail graph for that location -- for instance, click here for the Lake Shasta graph. You'll see that the levels are low and are still falling fast. There have been no calls for conservation, but if we don't get some rain, they'll be coming soon.
