Upper Clearfork. Low and clear, partly sunny. All brown trout caught and released on a #16 prince nymph, using 5x flourocarbon tippet. Wind came up so switched to #8 olive wooly bugger, stripped in slow water below swimming hole. No browns were tempted but 2 sunfish were hungry. Had to leave before dark so missed any surface action, unfortunately. Got try out my new Orvis Clearwater 5 wgt. Will be back.
