New Research Questions Hydroelectric Emissions

So what?

Hydro helps conserve petroleum for more useful purposes.

I wonder how much methane the reservoirs contribute to the atmosphere compared to the vast wetlands and rivers and other naturally occuring sources of methane?

In the big scheme of things, it probably isn't statistically significant.

Surely carbon rich material will travel to the sea where the flow slows and deposits it there instead, just fill the damed thing with cat fish and sturgeon they will soon eat it all up.
