Hey Rich,
Considering your lake has a large quanity of bass, wouldn't it be prudent to remove the bass first before stocking with more trout? Being that bass just love little trout and anything else they can grab. It would be a shame to spend a sizable amount of money on your trout just to have the bass eat em all. Not an expert here. Just know that a lot of very good trout lakes have been destroyed because bass were introduced to them. Either way good luck. I thought having a farm pond would be cool. You have a lake! Too cool!
