Here's the deal. Trout are the money maker. You better believe the WDFW makes a whole lot more through licensing of trout fishers than it loses through planting!

Warmwater fish (will refrain from using my usual name for them) don't have the appeal to fishermen that trout do. Yes, people fish for other lake dwellers, however the bulk of lake fishing is done for one species: Trout.

It would be foolish and cost the WDFW to turn away from stocking trout and their policy creating lake conditions (periodic lake kills) which are favorable to trout.
