MAYBE Flies on the cumberland!!

:rolleyes:MAYBE it's TIME....Water level in the river is down and I have not fished the Cumberland tailwaters for trout this year....BUT do have an OLD, I mean OLD fly rod which I purchased when I was in my teens, i.e. around 1955 (Guess you call those the "good old days"). MAYBE I should dig out the waders and head on down below the dam or to Helms(sp) landing....MAYBE I could use a little help on the what to tie on, etc...Any advice? What type of flies work best this time of the year? I have heard the term "match the hatch", but what is the hatch in late July/early August?:confused:
