Hi adamsquad.
It's been many many years since I fished LOPT, but when I did, I caught a few rockbass near the rocky shore line of the Roblin bridge.
I caught them on small curly tail grubs, but I think worms would be even better.
Try asking on the Manitoba form also, there is a bit more action on there, and probably some updates on how to fish for rockbass at
LOTP.
Good luck and welcome to my fishfinder.
