Hey Z, are we talkin rainbows? Was the water clear?
My boss's father fished it years ago and always did very well and caught large trout.
MIKINAAK, they were al rainbows, fished close to dam next to outlet. Water was about 8' deep and very clear.
Lake did have large trout years ago, but went dry about 3 years ago during the drought. Water was pretty low last year. Might want to check water level if you go.
