I used to live over that way and fished around the cove alot after work. (Single and no kids then) The cove gets alot of BIG carp when the Willow Flies are hatching and its a good place to sightfish them.
Try throwing buggers for them when you see them rooting in the mud. I've done it from the ramp.
Go down to Friendsville to the boat launch and little campground ( can't remember the name of it) and
fish around the floating dock at the ramp. I used to sometimes eat lunch there and get in a few minutes of casting. If the wind is blowing in, the shad bait balls will get close enough to cast a small streamer around and the white bass and small largemouths will usually be actively chasing the minnows out of the water. Lots of fun! I got a few laughs and snears from the Bass fishermen in the $40K boats until I hooked a 4 pd Largemouth in front of them on a flyrod fishing from the bank!
