Can any one help me understand how much current is created when they pull water for power generation? Or should I say at what release rates seem to be the best for positioning fish on ledges? This has been baffling me for a number of years and I know it is key for success when targeting a school of fish and I've heard so many different stories that I would like to print it out and keep it in my wallet for good. I am sure this will help alot of guys like me trying to understand.
