Making snow takes energy. (Basically, you need to spray a mist at high pressure, which includes pumping both water and air.)

Dams don't use energy once they're built. Hydropower is renewable and carbon-free.

Furthermore, if you're making snow to store water, you can't control when it melts, and you need to collect the water as it melts, most likely behind some kind of a dam!

Interesting. So the dammed water grows more algae than a moving river which leads to methane release (from the decaying algae?)

" “We were surprised to find that the biological productivity of the reservoir (i.e. how many 'nutrients' like nitrogen and phosphorus the reservoir receives and the associated degree of algae growth) is a better predictor of emissions than is latitude. So, the most biologically productive reservoirs are producing the most methane,” writes Bridget Deemer, the study’s first author "
