This may be old news but here goes: Early in the mornings the mature skipjack are in the fast water below Lock and Dam 16 (Webbers Falls). They are caught with long rods casting a string of three large 5/0 flies tied on dropper loops with a 4oz or 5oz sinker at the end of the line. There are scads of the smaller ones available all day long on tiny 1/32 jigs again tied in a string of three on dropper loops with a 1/4 or 3/8 oz sinker at the end.. Preferred colors include blue, yellow and multicolor jigs. The same conditions exist below most hydroelectric dams including Eufaula, all of the L&D's and some lakes that drain into the Arkansas River.
