Cosby or Indian creeks are good that time of year as well. Had a stellar trip last year second weekend of March. Flashback olive hares ears, tellicos, and by mid morning we were using#16 black, tan, and lime caddis. Lots of little stones, and caddis out. Not many mayflies saw maybe adozen or so Quill Gordons all weekend. Water temps were in the 40ies managed one temp reading of 50.2 Sun morning. Water temps will be cool but brookies are very tolerant of the cold.
On a really good note we had all the campsites and water to ourselves.
