One more thing I would like to add on the subject for everyone to ponder over. 30-40 years ago Biologists and Sport Fisherman alike said that the Kenai River in Alaska would never be fishable because there is too much glacier silt in the water. Due to the murky water fish could not possibly see a lure to hit it. Today it is one of the most world famous salmon and trout fisheries in the world...Morale of the story is never overlook any body of water.
