Blue Ridge uses no chlorinated city water in their grow ponds. It all comes from a nearby natural river. In fact, you wouldn't believe the size pumps that are used to pump the water into the lakes. Rick has the ability to know what is happening to each pond's water quality by the color of the water. He didn't worry about a few we saw that were in trouble.
Predators can be a big problem at a fish hatchery.
Blue Ridge has a great defense against them. I think her name is Shine. She's a bird dog specially trained to defend the lakes. She was not satisfied by all the pictures I took of her. She had to get into others.
