There was a big difference back then. WDF utilized "local" stocks. They did transfer stuff around but then used the returns to maintain the program. WDG used the mothership model which was much more economical.

For trout and various lakes (high and low) they maintained a variety of stocks rather than a single one-size fits all which is (again) cheaper.

My point was that, in the past at least, WDFW used local stocks which are less economical than a mothership operation which is why the agency, back then anyway, was certain that their operations were, overall, better for the State economically than just going cheap and buying the fish from private growers.
