Back home, I went on google maps to see what amount of water was actually left. Surprisingly, on google maps, the lake looked 100 percent full.
And here it is, real roads under virtual water. The deal is, if people are going to be able to launch their boats, you're going to have to build roads up to the edge of where the water actually is, that is several tens of feet below the surface of the virtual lake.
So map makers past fake water on top of the dry lake bed.
Curiously, in this particular case, the surface of the virtual water had a cool vortex right in the middle of one of the bays.
I was intrigued and curious if Google followed the same policy of topping off reservoirs with virtual water all around the state of California. I moved over to San Luis Reservoir just west of Los Banos. This reservoir was also way down the last time I drove by it.
The long view again showed a lake topped off to the brim.
But the closeups showed an un-doctored view, bathtub rings showing previous lake levels and trees growing on former lake bottom.
Research on this topic is continuing.
