That fly brings back memories of lake fishing with the ol' man.
We would flat-line troll propeller flies like that....typical color was a Cardinal red.
Also on a calm evening a flat-lined Muddler pattern would work well.
They make a nice little wake......and then wham !!

I've also had good luck drowning a dry fly pattern using the same flat-line trolling method.

The small size Flatfish in Michael Jackson is yet another flat-line trout whacker.

The pulsation of rowing, I think adds an advantage over motor trolling.

Flat-line = no weight.....tie directly to your bug and get it out 100' or so.

One more thing.....
Don't let them take your rod away....they WILL try to take your rod away.

Good luck !

Edit:
If this represents those shiners, then a Thomas Buoyant spoon will whack them very, very well.
I would add a split ring (or snap swivel) to the nose of Thomas and also continue with the flat-line method.
