What is your target species? If targeting bass then clear water rocky structure where spawning beds can be seen is the best. That would be main channel/main canyon rocky outcroppings any where from Bullfrog to lower Good Hope or Escalante to Bullfrog. Lots of places. Bass fishing is really good right now in clear water in the afternoons.
Stripers - best recent reports were trolling in the back of Bullfrog Bay. I would also try bays in Halls Creek, Lake Canyon, Slick Rock and Iceberg. My reports are second hand uplake as I have not personally fished up there this spring.
