"Was CV stocked in the same manner? with millions of fry? "

Would pretty much guarantee it. as mentioned before, the number used for Pine Coulee was actually pretty conservative. Survival of fry is very low, and walleye are rarely reared at hatchery to greater size due to their predatory nature at young age (try to eat each other). Initial plans included stocking over more years to diversify age class in PCR, pretty incredible how succesful the stocking was.
