Probably one of your best midday fishing options these days, and the morning and evening fishing is very good.  Like the Blackfoot, Rock Creek has more riffles and faster water than the ‘root or Clark Fork allowing the fish more protection from direct sunlight (fish do sunburn you know!) and predators.  The hatches are good up here and the fish are looking.  With a flow of 489 near Clinton this morning, conditions are ideal for wading the creek top to bottom.  PMDs and smaller attractors and caddis patterns have been effective for us.  Rusty spinners in the evening have been out -fishing the caddis for us lately even though there will be WAY more caddis on the water.  Rock Creek will treat you right today.
