would try Ft Loudon lake, per a map I have, it says Turkey Creek, Little Turkey Creek, Sinking Creek and Prater Flats. I've fished Prater Flats years ago, but that was 25 yrs ago. Map/book also says Concord park, Poland Creek and Ish Creek/Prater Flat area. There is a bait shop near concord park that may have some current info ya. Douglas is an hour northeast, better fishing in all probability, maybe someone from the Dandridge area will chime in.
GO BIG ORANGE !
I meant to behave, but there were just way too many other options available at the time.
