Could easily come from a “sleeper lake”. While many are ancient history look at the huge bass that showed up on lakes not necessarily know as a state record contender. Possum Kingdom, Pinkston, Austin, Mill Creek, Sam Rayburn, Conroe..... while “smaller bass” remember Monticello and Welsh each had the state record at one time....in the 80’s. John Alexander broke the state record twice in a couple weeks on private Lake Echo. Have to agree though that Caddo has as good a chance as any lake....including Fork. It has turned out some giants in a more recent history. While not that big of a reservoir there are places on Caddo that big fish can remain out of touch from the fishing population for long periods of time. Here’s the Texas Top 50 bass list: https://tpwd.texas.gov/fishboat/fish/programs/fishrecords/freshwater/top50_largemouth.phtml

Nachoniche will be taken over by salvania in 3 years. I have never seen so much.

some of those fish secretly came from fork but was lied about.

Actually Senko I heard the opposite. Some of the teenagers from Fork were rumored to have come from other lakes close to Fork and brought over for various reasons. The change around 1993 was the run on killing out invasive grasses such as hydrilla by the state and spraying began along with aging lakes, increased pressure, and development around lakes like Fork.
