yeah, I tried something like that, but there are 48 reservoirs represented on the graph and so you aren't going to be able to read all of them regardless. I did add the ability to select which reservoirs to show on the graph (in the interactive version) which can let you visualize the smaller reservoirs.

But the overall goal was to show the amount of water in reservoirs so it's not that helpful if a tiny reservoir (amounting to less than 1% of state storage capacity) is full
