Wasn’t there a ‘super scooper’ that did just this this weekend?
Also, I heard California won’t allow lakes to be used for a water source for wildfires. I haven’t verified.
It might be hard to get the big tanker planes down into some of those lakes. There have been multiple references from various news channels to the choppers drawing from the lakes, however. Maybe that only applies to some lakes?
The “scooper” planes can draw from the ocean if it is not too rough. How rough that is, I don’t know. Sucking up water would work in rough seas, but I’m sure it is much slower.
