Dynamo is not far away from Bodie, I think it is a man made lake used to provide power to Bodie. Bank then they thought electricity could only travel in a straight line so there is a straight shot from Dynamo to Bodie. If memory serves me correct some of the old power poles are still erect.
Just looked it up on Google Maps and realized I've fished there! Me and a buddy found it by accident on time and gave it a shot. I remember that wood dam because we tried fishing off of it. Think we got skunked.
