If it was a White catfish, it would have to weigh 2lbs or more to be a state record.
Here's the scoop on Guist Creek's record White Catfish --- from 2004 :

.................................................. ..................................
Another record catfish bit this past May. Charlie Crain of Shelbyville still fished a night crawler at Guist Creek Lake on May 3 when an unusual catfish struck his line. It is now the state record white catfish.

Kentucky possesses small populations of white catfish. Native to the Atlantic coastal streams such as the James River in Virginia, a population of white catfish swim in Guist Creek Lake.

Crain’s record white catfish weighed 1.82 pounds. It was 16 inches long with a girth of 8.6 inches. It bested the old record of 1.78 pounds caught by Stephen Daisey from Guist Creek Lake in August, 2002.

Now, with that being said ... KDFWR has netted a 8lb White Catfish, from Guist Creek, back in 2007 (I think) .... so there's still an opportunity to get on the record books.

The state record Bullhead came from there, also ... over FIVE POUNDS.
