I don't know but...
Sponserd by "Southwestern Energy", checking to see what kind of real water capacity ??? I will say this, if you wish to really mess up a good fishery build a dam and start generating power. The cold water, taken off the bottom of the lake, ruins the warm water fishery downstream and the continual flucuation of the lake level due to discharges while generating power messes with plant growth and fishing in the lake. Study Lake Greeson if you do not believe it.
