I feel like the photos are always dramatic, but it's really hard to interpret. For one thing its not clear the photos are from the same time of year. But even with photos from the same time of year, we visualize surface area and visibility of "bathtub ring", not volume.
Actual data is here: https://cdec.water.ca.gov/resapp/RescondMain https://cdec.water.ca.gov/resapp/RescondMain. It seems Lake Oroville, the resevoir featured in the article, and Cachuma are the only ones that are well above historical average.

- surfpel 4y agoI find this* graph most helpful. In one graph it displays all of Californias reservoirs with their current level, their historical average, and their level 1 year ago vs their capacity. It also shows the relative sizes to one another. The reservoir from the article (Oroville) is one of the only ones to have made such a recovery. * - https://engaging-data.com/ca-reservoir-dashboard/ https://engaging-data.com/ca-reservoir-dashboard/
- s1artibartfast 4y agoWhat a beautiful and rich data visualization!
- jabo 4y agoI second this. Thank you for sharing! I wonder if this is a custom visualization pattern, or if there is general a name for this type of visualization. Does any one know?
- mikeyouse 4y agoThe author talks about them a bit below the chart in that link. Apparently it’s called a marimekko visualization or a mosaic plot: https://datavizcatalogue.com/methods/marimekko_chart.html https://datavizcatalogue.com/methods/marimekko_chart.html
- xmddmx 4y agoThis one shows reservoirs + snowpack (which I think is ultimately what matters most): https://engaging-data.com/california-reservoirs-and-snowpack/ https://engaging-data.com/california-reservoirs-and-snowpack...
- WillPostForFood 4y agoIt seems Lake Oroville, the resevoir featured in the article, and Cachuma are the only ones that are well above historical average. Lake Oroville is at 115%. New Bullards is at 120%, Pine Flat is at 121%, Folsom and Camanche at 111%.
