Tried another spot. Water still murky, but enough current and depth to hopefully get something.
I used a larger bucktail fly (can't remember name) that floats really well (used as strike indicator) and added a 18" dropper to a beadhead nymph.
Caught four white perch in the current seem.
I changed the bead head for something more creature looking, maybe slightly larger, and caught nothing.
Went back to the beadhead and caught the 5th white perch and packed it in.
Learned something. How picky they can be and the spot they came out of.
