Little to no predation or harvest, pristine spawning habitat and conditions, and abundant food. The perfect recipe for trout to grow plentiful and large.

There are several other lakes close by with very similar conditions in which trout were planted as well, but for some reason none have exploded the way Strobel has. The locals say it is all due to the food source, but I think the recipe is a little more complex than that. I've heard some say water temps and mineral/nutrient content play a role.

I've read a number of places that the rainbows transported to Argentina, Strobel included, came from the McCloud in, CA.

This book has some good background in addition to the usual where, when, what info:
