Never have fished Fork but it is one lake on my bucket list. Fork is known for it's trophy bass. Where ever you have a nice population of trophy bass you are going to have a nice population of trophy Bluegill/Sunfish. I have seen past post on other sections of this forum showing nice Bluegill and Crappie caught on Fork.
Side Note: Would love to see a Bluegill catch or post off of Fork !
